We encounter some difficulties at the beginning of our project. Professor Lin Wenxiong helped us a lot when we were looking for a new way out. We made a hardware model , but it was difficult to be used widely, because of the cost. Professor Lin told us that the products we made may not currently make great economic profits in the market, but as long as the products are valuable and can help achieve carbon neutrality, it is a valuable product, and in the future we can continue to carefully study ways to reduce cost. In addition, in the education section, we have planned to enter the campus to lecture and hold academic exchanges , but the forms are rather limited and not interesting enough, and we are worried that it will be difficult to attract public attention. After hearing this, Professor Lin first affirmed that our idea was scientific and he expressed his willingness to help us call on the public to pay attention to the water environment management problem. This gave us great encouragement and confidence.
We were worried that the format of campus lectures and academic lectures were rather rigid and can not effectively shorten the distance between scientific communication with the public. Professor Lin gave us an easy-to-understand example: when watching the cartoons when I was a child, I still remember the characters very clearly. Why is this? Because the animation or cartoon cartoonizes the boring stories, and the interesting conversations make it easier for us to remember. Therefore, when carrying out education and publicity, more scientific knowledge can be personification, which is more conducive to the dissemination. This suggestion helped us open our minds, and we also listened to Professor Lin's advice, and made special hand-painted books to support the reading from primary school to college, and even for adults.
After we finished making the science book and hand-painted book, we contacted Professor Lin to get some guidance and suggestions. Professor Lin admired our science book and hand-drawn book while flipping through them and reaffirmed our approach. After reading them carefully, Professor Lin suggested some changes on the framework to help us further improve the book content, which helped us a lot.
In short, the communication with Wenxiong Lin promoted the progress of the project, and we also got the idea to solve the problem. At the same time, we are very grateful to Professor Wenxiong Lin for his support and encouragement to our project, which is of great significance to put the laboratory results into practical production and application.
On September 29th of this year, we conducted an interview with Prof. Qiang Wang after the Chinese Society of Plant Physiology and Molecular Biology. We benefited a lot from this activity, and through the professor's guidance, we also understood the future plan and prospect of the project development, which is very meaningful.
In this process, we firstly introduced the composition of our team and and the role of each classification to Prof. Qiang Wang. The professor listened carefully to the composition of our team and gave us some suggestions, such as the appropriate division of labor in the team. We also learned that Prof. Wang's research interests are mainly in algal biology, photosynthetic environmental stress response and synthetic biology. We also learned that Prof. Wang's research is focused on photosynthesis, environmental stress response and synthetic biology, and that he has taken photosynthesis research model materials, cyanobacteria and Chlorella, as the research objects, based on photosynthesis and synthetic biology, focusing on environmental problems, and conducting systematic research around scientific problems such as microalgae environmental adaptation, bioenergy and bioreduction, which is closely related to our subject direction and research direction.
Then we introduced our team's research direction to Prof. Qiang Wang, the feasibility of microalgae for wastewater treatment and the feasibility of extracting the high economic value products Phaeodactylum tricornutum,EPA and biodiesel from microalgae for wastewater treatment, Prof. as the research objects, based on photosynthesis and synthetic biology, focusing on environmental problems, and conducting systematic research around scientific problems such as microalgae environmental adaptation, bioenergy and bioreduction, which is closely related to our subject direction and research direction. Then we introduced our team's research direction to Prof. Qiang Wang, the feasibility of microalgae for wastewater treatment and the feasibility of extracting the high economic value products Phaeodactylum tricornutum,EPA and biodiesel from microalgae for wastewater treatment, Prof. Qiang Wang spoke highly of our ideas and gave full affirmation to our ideas, he explained to us that microalgae have fast growth rate, high CO2 fixation efficiency and He explained to us that microalgae have high growth rate, high efficiency of carbon dioxide fixation and photosynthesis, and can absorb and degrade the pollutants in the sewage during the growth process, thus playing a role in purifying the water. In addition, the application of microalgae in wastewater treatment has the following advantages: the use of microalgae biomass for fertilizer production, the recovery of assimilated nitrogen and phosphorus, and the resulting microalgae biomass can be used for the production of biofuels, functional foods, animal feed and pharmaceuticals, etc. In addition, microalgae reoxygenate wastewater through photosynthesis. Based on these advantages, more and more researchers are focusing on the use of microalgae to treat wastewater, leading to the rapid development of this technology and its gradual move towards practical engineering applications. We asked the professor about the advantages of microalgae treatment of sewage and feasible methods, and Professor Qiang Wang explained to us, "Microalgae assimilate and absorb pollutants such as nitrogen, phosphorus, heavy metals and organic matter in sewage during the growth process to purify the water, which greatly reduces the treatment cost and the chance of secondary pollution compared with physical-chemical methods. In future work, the focus should be on the practical application of microalgae treatment of wastewater and biomass production coupling technology to fully exploit the economic potential and environmental benefits of microalgae.
However, there are still some technical problems to be solved for the industrialization of this technology. Firstly, it is necessary to domesticate and screen high quality algae species that effectively purify water and select those with high content of oil or bioactive substances. Secondly, an economical and efficient technology for separating and harvesting microalgae should be developed. Finally, a light reactor suitable for the growth of microalgae and which can be operated on a large scale should be developed."
At the end of the interview, we had a group photo with Prof. Qiang Wang. The use of microalgae to treat wastewater provides an environmentally friendly path to alleviate water pollution. It is believed that with the development and breakthrough of technology, the water purification and biomass production coupling technology based on microalgae culture will have a broader prospect in the future when the shortage of resources and energy is becoming increasingly severe.
We often encounter problems in the course of our experiments that cannot be solved by our team members' discussions, so our team keeps a wide open-minded and inquisitive attitude. Seeking help from some experts and scholars can further expand the team experiments and get more novel ideas at the same time.
Prof. Yanling Zhao is mainly engaged in marine microbial ecology research, and conducts microbial genomics and comparative genomics research with marine dominant bacteria and phages of great ecological significance.
Considering Professor Zhao's area of expertise, we also targeted some questions. Prof. Zhao pointed out that besides purifying the seawater environment and assistant marine carbon balance, we also need to pay attention to the conservation of marine diversity. Therefore, we also consider the fixation of algae strains in the design of the laboratory to prevent them from spreading in the water column and causing pollution. Prof. Yanling Zhao also gave us valuable advice on the genetic recombination of Trichoderma reesei. Prof. Zhao mentioned that we must consider all possibilities when designing experiments, which is a great inspiration for our experiments. Considering the possibility of accidental infection, we will do more biological replicates and repeat sterilization during the operation. When the results of several experiments are inconsistent, we will review the literature to see if the protocol needs to be changed. In the recombinant lab we usually design several protocols to avoid unexpected effects on the results. At the same time, she gave great recognition to our project, "These microorganisms have a huge number and diversity, and what researchers know about them now is just the tip of the iceberg, and it is very meaningful to keep discovering and exploring the value of using microalgae in research to apply them in real life."
"The burden of cultivating a new generation of young talents is not easy, and I often reflect on myself: what do students need? How to guide students well? Is the guidance adequate?" In Prof. Yanling Zhao's view, the primary responsibility as a graduate student mentor is to guide students well, provide them with a platform for research, and stimulate their creative ideas. She always hopes to spare more time to guide students and promote joint progress. When students encounter difficulties in their experiments, she will work with them to find the reasons for their failures, trace every step and process of the experiment, and find solutions to problems from analyzing the source. Prof. Zhao's words also inspired our team to be more creative and to stimulate their interest in learning when the project reaches out to people of all levels. In the subsequent "Blue Carbon" sessions, time was set aside for students to ask questions and organize craft activities to generate interest.
With the industrialization of cities and the improvement of people's living standards, more and more domestic and industrial wastewater is generated. The traditional wastewater treatment process turns the organic carbon and ammonia nitrogen in the wastewater into carbon dioxide and nitrogen gas to the atmosphere through massive aeration and alternating anaerobic and aerobic operation, without recycling in the form of energy or resources. With the depletion of fossil energy and the increasing greenhouse effect, the search for more energy-efficient and environmentally friendly wastewater treatment processes has become very urgent. We hope that Brown Finger Algae Triangle will soon be applied as an effective product for wastewater treatment at a low cost.
We introduced our project principle to president Zeng in the form of a PowerPoint presentation, which intends to use Phaeodactylum tricornutum with multiple iterations of PTCA and other genes to sequester carbon to slow down global warming. We also aim to improve the ability of microalgae to adsorb heavy metal elements to solve the problem of excessive sewage discharge. President Zeng believes that algae are a good entry point to mitigate climate change, as they do not take up arable land and are not harmful to the ecosystem, but it is worth noting how to fix and apply this tiny organism. In response to this currently unsolved problem of algae fixation, President Zeng gave us new ideas. He pointed out that the algal spheres might block the material flow and that muddy materials might be a better choice. The team members also said they would try more here.
In addition, we showed Principal Zeng the activities that the team has already held in the education section, such as environmental walk, tri-
fold distribution, etc. Principal Zeng gave us high praise and said that this is a field worth exploring, which is full of opportunities and possibilities despite the treacherous road.
President Zeng pointed out that our PPT was not clear enough and that we could use the carbon and nitrogen cycle diagrams to analyze the links with high emissions to design experiments more realistically, and we could use videos or animations to explain the project process more clearly and intuitively. When reporting the results, we can also use diagrams to express the purification effect of Phaeodactylum tricornutum.
The affirmation from Principal Zeng gave the team confidence that our efforts would allow more audiences of all ages to learn about this algae that does not take up arable land and produces high value by-products. It also provided us with new ideas for our project presentation, learning a new way of visualizing and persuading the cycle diagram.
Many iGEM projects can eventually be put into actual production applications, especially for us who eventually want to put the technology into practice. To move to actual production based on the theoretical basis of the laboratory, this is definitely not enough for the experiments done in the laboratory, which involves other factors such as economic interests, production efficiency, social needs and so on. And there are many processes and difficulties that we don't understand. That means we need to talk to a business that is actually going into production. There is a company in our local area, Fujian Shenliu Group, which has researched on the production and application of spirulina. On July 3, we decided to go to Fujian Shenliu Group to conduct research and interview Xie Jinjian, the person in charge of the group, in order to understand the company's understanding of pollution control technology and its opinions on microalgae treatment technology. Through this interview and communication, we have learned about the company's views on advanced sewage treatment methods and the development status of local pillar industries, have a deeper understanding of the application of project technology, and have also promoted the practical application of our technology.
Since Fujian Shenliu Group has researched on the production and application of spirulina, we have raised questions about the company's current technical or cost difficulties in treating sewage. We believe that at the technical level, the use of microalgae to treat wastewater is an ecologically sustainable technical method, which can absorb and degrade pollutants in wastewater by exerting the synergistic effect of algae and bacteria. The entire treatment process is not only low in energy consumption, but also promotes the recycling of nutrients such as nitrogen and phosphorus, and at the same time achieve the purpose of controlling greenhouse gas emissions. At the cost level, we believe that the techno-economics are not recognized, so it is necessary to carry out comprehensive development to improve the sustainability of the technology and reduce the cost, and we also consider that the environmental risks are also to be further evaluated. In general, large-scale production and utilization of microalgae remains a technical challenge. Accordingly, Xie Jinjian replied: Different treatment processes will produce different operating effects, and operating costs will also be different. Large-scale sewage treatment plants mostly use traditional activated sludge method and its deformation process, while small-scale sewage treatment plants mostly use oxidation ditch process. However, he believes that microalgae wastewater treatment technology is a green technology with great potential and has broad market prospects. We need to investigate new microalgae wastewater treatment processes from the aspects of pollutant treatment efficiency, process energy requirements and economics, pay attention to product development of algae, propose sustainable treatment technologies, and promote wider application of microalgae wastewater treatment. This may be related to the fact that most of the wastewater treatment technology with microalgae stays in the laboratory stage. For Shenliu Group, the annual expenditure on wastewater treatment is a large amount. Therefore, they do not know much about the cutting-edge sewage treatment technology.
We also raised the question of where to start our research projects if we want to cooperate with companies. Because our project is currently progressing slowly in cooperation with enterprises, in this regard, we would like to have practical cooperation with Fujian Shenliu Group Company. Fortunately, Xie Jinjian believes that school-enterprise cooperation and the combination of production and education are good ways. He said frankly that he hopes to achieve resource sharing and win-win by establishing a work-study practice base. Let the advanced corporate culture enter the campus, enterprise management into the classroom, production management into the base, in this way to help improve the quality of talent training. It is reported that Fujian Shenliu Group has achieved remarkable results in talent training through several years of school-enterprise cooperation, and team members have also gained a deeper understanding of the company's culture through this exchange and practice exchange to promote the actual promotion of our project.
Through this communication with the company, we learned a new observation angle. From the market point of view, it is necessary to investigate the new microalgae wastewater treatment process from the aspects of pollutant treatment efficiency, process energy consumption and engineering economy. In particular, we should pay attention to the product development of microalgae, propose a sustainable development route based on the concept of circular economy, and use the microalgae treatment wastewater technology as the source rather than the terminal of the microalgae product development process, so as to promote the wider application of microalgae wastewater treatment. President Xie Jinjian's introduction to the historical development of Shenliu Group also made us understand the company's views on sewage treatment methods and the development status of local pillar industries, and gained a new understanding of the sewage treatment work carried out in this project.
We are very grateful to have this opportunity to interview the president of Fujian Shenliu Group Xie Jinjian while conducting on-the-spot investigation of Fujian Shenliu Group. Throughout the year, we encourage dialogue with different groups, as we hope to measure the practical significance of our projects. Regarding the suggestion given to us by President Xie Jinjian, we have determined that if we have the opportunity to personally go to the enterprise to practice, the practical application of the project will be greatly improved.
In a meeting summary, one of the team members mentioned that we should go to the field to study the wastewater plant further understand the mainstream of the current market for wastewater treatment, and to find some inspiration for our team project. After tcommunication, we contacted the person in charge of the Jinshan sewage plant, who agreed to visit the plant and answer our questions The person in charge told us that the drainage system of Jinshan Wastewater Plant adopts a split flow system, and adopts a modified process of SBR - ICEAS wastewater treatment process , using the depth treatment process of " high efficiency sedimentation + filter cloth filter tank ", and the wastewater treatment reaches the standard of "urban wastewater treatment plant pollutant discharge standard" in Table 1 of Class A. After the initial understanding, we also told the person in charge of the principle and method of microalgae treatment of sewage. Microalgae have certain treatment effect on harmful sewage containing pesticides, antibiotics, heavy metals, etc., and have the effect of adsorbing toxic and harmful substances such as heavy metals within a certain concentration range. Our project is to modify the ability of microalgae to absorb N and P elements through transgenic technology and play a greater role in sewage treatment. He appreciated our project and mentioned that most of the wastewater plants have not yet used microalgae to treat wastewater, which is mainly due to the fear of high cost, unknown risks of the new technology, etc.
According to the United Nations Sustainable Development Goal No. 6: Everyone should have the right to clean drinking water and water use, in order to ensure that more people understand the knowledge related to water conservation, water love and water protection, and to raise good awareness of resource conservation, our government has also formulated relevant policies to monitor the sewage data testing of factories, enterprises, sewage plants, etc., and adopted a transparent and open system so that the public has the right to know what social institutions have to say about sewage treatment programs. This will help to improve the quality of life of people and the natural ecological environment.
Although the Jinshan sewage plant does not use the technology of microalgae to treat the sewage, the person in charge knows something about the method of microalgae treatment of sewage. After communication, he told us that pesticides, antibiotics, etc. can be degraded or adsorbed within the tolerance limit of microalgae. This point gave us a direction to think about, and for the adsorbed algae, we plan to study it again later to achieve pollution-free treatment through thermal cracking and other forms to further improve the project's treatment system.
Yangkou Town, located in Shunchang County, Nanping City, has a history of more than a thousand years. Currently, is now recycling excrement jointly with enterprises to obtain more additional production value and promote zero-carbon industries. Huang Naigan, Minister of Yangkou Town Government, is an expert in applying environmental governance to practice. We were inspired by the story of the governance environment he conveyed, and his efforts to capture the audience's attention, so we decided to reach out to him for their feedback on the way we present our projects. We hope that through this interview, we can learn about the measures the local government has taken on the governance of the rural ecological environment, so that we can better understand what publicity we need to do to contribute to raising the public's awareness of environmental protection.
In July this year, we interviewed Mr. Huang Naigan, Minister of the Armed Forces of Yangkou Town, Nanping City, at the Yangkou Town Government. The subject of this interview is mainly about how Yuyangkou Town has taken the zero-carbon Shunchang concept as its foothold and realizes a series of innovative measures such as environmental governance and ecological protection. As far as we know, Shunchang County has been working hard for rural environmental governance in recent years. Huang Naigan also proposed: In order to implement the zero-carbon Shunchang concept. Yangkou Town's work on ecological governance has been implemented in all aspects of life, starting from the management of rural domestic waste and in accordance with "reduction first, encourage classification, urban and rural overall planning, and comprehensive management". Our team also thought of this in advance, so we put forward more in-depth discussions on the rural governance environment. After learning about our project, Mr. Huang Naigan now expresses his affirmation. He said that in the early stage of treatment, we were very troubled with sewage treatment. Many villagers would wash clothes by the creek, but the water quality was poor. It took a lot of energy and material resources. He said that our project can, to a certain extent, conduct popular science on water control for the masses. It can be seen from our active discussions on site that the government is very concerned about this aspect. During our communication, we talked about the need to strictly implement a series of measures such as the implementation of the management system in order to control the rural water environment.
We not only exchanged our experience in rural environmental governance with him, but he also gave positive comments on our educational activities over the past year. The focus is on popular science education for people in underdeveloped areas, and we take into account the scientific and environmental aspects of the project, as well as privacy. In his opinion, our interesting popular science propaganda has caught his attention. Regarding the method of popular science education, he strongly suggested that we use the form of art to popularize some incomprehensible synthetic biology knowledge. All in all, this interview brought fun to everyone and gave us new ideas on how to conduct educational activities.
First of all, thank you very much for having this opportunity to communicate with Mr. Huang Naigan.
On October 9th of this year，We carried out a small class to support teaching to children in remote mountainous areas at Guangxi Laibin City Wuxuan County Experimental Junior High School , explaining to them the basic content and knowledge about synthetic biology, giving them an initial enlightenment about biology, which has a significant and far-reaching impact.
We took this opportunity to go into the mountain village and learn about the lack and scarcity of educational resources for the children in the mountainous area, and we also learned that the environment and conditions are very backward due to the geographical location and transportation. After understanding the situation, we wanted to help them learn more with our own power. So we started our teaching activities here. In the process, we educated the children about synthetic biology and briefly about our project. We not only talked about the origin of life, the cell, but also taught them about the life of a cell and that people are made of cells, and the children were very interested. At the same time, we showed them the hand-drawn book that we designed and drew ourselves and introduced them to our topic of microalgae through the hand-drawn book. The children were very curious about the biological knowledge and asked us questions, and we answered them patiently.
After the popularization of science, we took a group photo with the children to record their thirsty faces for biological knowledge. At the same time, we also asked them what they wanted to know so that we could do the science fair next time. We to protect the water resources, advocate garbage classification as a starting point, hope can for high school students to preach about sewage treatment technology, the prevention of water pollution, garbage classification and so on, so as to make students form and strengthen the consciousness of environmental protection and garbage classification and form a relatively complete system of environmental protection and the related method, the important thought of the promotion of green environmental protection, Make garbage sorting and water resources protection a good trend and conscious action for more people.
We are very aware of the importance of reaching out to people associated with the discipline of synthetic biology and informing them about it. This year, we decided to communicate with our students on campus about our project in order to gain a comprehensive understanding of the impact, utility and nature of the project and the application of our proposed solution. The traditional teaching model is fixed in the room and limited by time, space, equipment, etc. We wanted to break this barrier in an easy way, so that students are not limited by the school LAN and geographical restrictions; break through the spatial restrictions, teaching and learning not necessarily indoors, but also outdoors. So we decided to set up a mobile classroom in Topside Square of Fujian Agriculture and Forestry University to promote our project through posters, video broadcasting, brochures, etc.
We noticed that some students in our school are relatively backward in their understanding of science knowledge, and we popularized science content as close to life as possible, such as the introduction of microalgae and the interpretation of gene editing. We believe that similar outdoor classes can inspire students to learn intensely and will be an unforgettable experience for everyone. In addition, we produced some interesting science cartoons, hand-drawn books and brochures on biological evolution, synthetic organisms, etc. For example, used microalgae to treat sewage as an example to tell students about the amazing effects of microalgae, so that students could understand that biology is not only limited to the visible range, but also the amazing microscopic organisms. At the same time, we distributed a paper version of our questionnaire to collect the knowledge of synthetic biology among the university students.
Our idea was well received by students as well as school teachers, who believed that the teaching content of modern education system should not be limited to traditional subjects such as language, mathematics and English, and that this kind of science popularization and competition could open up students' horizons and cultivate their interest in science, as well as contribute to the sustainable development of cultivating new STEM talents with the 2022CHINA-FAFU iGEM team's modest contribution.
On September 17, we conducted an online meeting with Guangxi University GXU-China and Nanjing Foreign Language School Nanjing_NFLS to interview experts together. At the same time, we formed the Fresh Freshwater Bioremediation Alliance (FBA). We jointly invited Professor Shen Xia from Nanjing Academy of Water Resources and asked him questions about wastewater management.
During the meeting, we asked Prof. Shen Xia about the governmental and private aspects of wastewater management, and she explained to us critically the channels and methods of wastewater management. Then, she introduced to us in detail the methods of sewage treatment, i.e. through physical, chemical and biological methods. The application of engineering bacteria is the biological method, in fact, it has two major advantages, first of all, it is a relatively low cost and no secondary pollution. In our national water treatment, including the treatment of sewage treatment plants, as well as the treatment of natural water bodies, all include the application of microorganisms. At the same time, Prof. Shen Xia also taught us the method of microbial treatment and the feasibility of machine treatment of sewage. We also consulted Prof. Shen Xia about our project - about the feasibility of microalgae treatment of sewage, and the professor fully affirmed the authenticity and feasibility of our project after understanding it, and encouraged us to continue our efforts towards the research direction.
At the end of the meeting, FBA had a relevant discussion, we deeply understood the current situation of sewage pollution and treatment, we gathered together to discuss each team's treatment and solution for sewage, and understood the situation of each of them. We each provided suggestions and plans for each other's development, which were approved and supported by everyone. With the development of science, the progress of the times, and the rapid growth of population, the water resources on which human beings depend are polluted and the amount of water we can drink and use is unknowingly decreasing. The issue of water recycling is gradually receiving widespread attention from the society, and the solution of a series of problems such as eutrophication of water bodies, excessive bacterial content and harmful residues is imminent. In implementing the 17 sustainability goals proposed by the United Nations, we also discussed the feasibility of microalgae treatment of wastewater technology in practical production applications in this conference, which provides experimental ideas for the laboratory and is of great significance for putting the laboratory results into practical production applications.
