− | <p> As the project continues to advance, HP's exchanges and cooperations between teams are more frequent and in-depth. After seeing the cooperation application issued by the iGEM team of the Indian Institute of Technology (IIT-Madras) at the iGEM official website, we contacted IIT-Madras to discuss cooperation actively. <br>
| + | |
− | We are pleased to collaborate with the iGEM team of the Indian Institute of Technology, Madras (IIT-Madras) to make a video on the science of synthetic biology in the mother tongue. The Indian Institute of Technology is also working with other teams in English, Tamil, Telugu, Kannada, Malayalam, Marathi, Bengali, Gujarati and Hindi. <br>
| + | |
− | IIT-Madras sends an English script to our team. We need to match the provided slideshow video with the provided text and add the translated text to the subtitles, and finally make it into Chinese video. <br>
| + | |
− | We thought it was a simple matter, but there were some problems at the beginning. The problem is summarized as follows: <br>
| + | |
− | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The English script does not exactly match the sound in the video, and some paragraphs are missing. <br>
| + | |
− | 2. English and Chinese belong to different language families. They are slightly different in grammar, and the word order is reversed in translation. <br>
| + | |
− | 3. Some video pictures and sounds are out of sync and need to be adjusted. <br>
| + | |
− | 4. Our team members are not familiar enough with the Indian accent in English, and some words cannot be completely accurate. <br>
| + | |
− | After consultation and repeated revisions by the iGEM team members of the Anhui University of Technology, four days later, the results were satisfactory and the video was sent to the iGEM team of the Indian Institute of Technology. We have established a good relationship with the iGEM team (IIT-Madras) of the Indian Institute of Technology, Madras. <br>

| + | |
− | <p> We know that environmental pollution is mainly air pollution, water pollution and soil pollution. Our project is to deal with greenhouse gas CO2 in air pollution. How to deal with greenhouse gas CO2 efficiently is particularly critical as the increasing greenhouse effect has a serious impact on the global environment. In order to gain a deeper understanding of the current environmental pollution in China, we visited HuaQi Environmental Protection Company. HuaQi Environmental Protection Company, is a company specializing in sewage treatment. After Ms. Zhang Qi introduced the company, we visited the intelligent water transportation management system and laboratory. </p>

− | <p > Liu Shanshan, the company's technical staff, led us to visit the laboratory. During the visit, we learned that water pollution currently is harmful to the environment and people's health. So, water pollution treatment is very important. We introduced our project to computerize the protein molecules expressed by carbonic anhydrase gene mutations to obtain carbonic anhydrase (CA-2) with high thermal stability and import it into E. coli cells in order to achieve efficient collection of CO2. The project is currently in the theoretical stage. She is interested in our project. If the CO2 emission can be effectively controlled at the source, the problems such as the continued destruction of ozone layer, the melting of two-stage glaciers and the rapid extinction of a large number of species can be effectively solved. And she is more concerned about how this project can be applied in practice, and puts forward some suggestions for our project. At present, the CO2 gas capture technology mainly includes chemical absorption, pressure swing adsorption and membrane separation. She suggested first that transgenic E. coli be cultured in solution environment with chemical absorption to achieve CO2 collection, and secondly that CO2 be treated with biological rotating disc. </p>

| + | |
− | <p> On September 8, 2018, our AHUT-China team visited the Biofilm Process Water Purification Laboratory of the College of Architecture and Engineering of Anhui University of Technology. The graduate student Xu Fan led us to visit the laboratory. The seniors introduced us to the principle of purifying sewage in the laboratory, which made us understand that relying on the microbial membrane fixed on the surface of the carrier to degrade organic matter has the characteristics of good effect and low technology and low cost. </p>
| + | |
− | <p> Then we introduced our project to the seniors. The seniors said that many problems caused by CO2 also brought us many problems. Therefore, he has great hope for our project. At the same time, we have learned that the biomembrance process can not only treat sewage, but also can be applied to the treatment of organic gases. The pollutants in the organic waste gas are first contacted with water and dissolved in water, that is, diffused from the gas film into the liquid film; The organic pollutant components in the liquid film are diffused to the biofilm by the difference in concentration, and they are captured and absorbed by the microorganisms therein; the organic pollutants entering the microorganisms are decomposed as energy and nutrients in the metabolism of the microorganisms themselves. This provides us with some ideas on the combination of theory and practice. </p>
| + | |
− | <p> Through a visit to the Biofilm Process Water Purification Laboratory in the afternoon, we learned about the biofilm treatment of sewage. At the same time, we also learned the necessity of our project. The impact of greenhouse gas CO2 cannot be underestimated. We also hope that our project can be applied to practice. The knowledge of biofilm processes in the treatment of organic waste gases has also given us some inspiration, and we may be able to use this knowledge when dealing with CO2. </p>

| + | |
− | and Discuss Project with Professor Xia Xu</h4></div>
| + | |
− | <p>
| + | |
− | On Sept.26,2018,members of the Team AHUT_China were very honored to visit the biochemical research center and visit professor Xia Xu.Professor Xu is a doctoral supervisor.Her research direction is mainly based on molecular simulation,which is designed for drug delivery, CO2 capture and transformation, biological materials,anti-microbial, disease treatment and functional polypeptide in vitro-detection, tissue engineering, regenerative medicine, microfluidics, online detection technology and so on.</p>
| + | |
− | | + | |
− | <p>We communicated with Prof. Xu about the project of absorbing CO2 in the air by introducing the synthetic modified carbonic anhydrase gene into escherichia coli and raised some relevant questions, and she gave us detailed answers.Here were our interview content.</p>
| + | |
− | <div align="center"><img src="https://static.igem.org/mediawiki/2018/c/cd/T--AHUT_China--_huagong1.jpg" width="300" height="300" alt=""/></div><br>
| + | |
− | <p>①Q:The laboratory has synthesized the gene sequence of human carbonic anhydrase by the total synthesis method, which, as far as we know, is a little bit different from the original one. May I ask you what these differences are?<br>
| + | |
− | A:Compared with the natural one, the synthetic gene of human carbonic anhydrase by the total synthesis method replaces the 203rd amino acid.As a result,the synthetic gene performs more stable when exposed at high temperatures.Our main application scenario is in the factory, so the modified human carbonic anhydrase must be highly active under such conditions.<br>
| + | |
− | ②Q:Our project is to introduce the full synthetic gene sequence of human carbonic anhydrase into escherichia coli through psb1c3 carrier to achieve the goal of absorbing CO2 in the air through carbonic anhydrase. Therefore, we want to get some information about the frontier in this field home and abroad, for instance, the technology of absorbing CO2 in the air through biology or other methods and so on.
| + | |
− | A:So far, the most advanced way in the world uses algae as the carrier for absorption, and researchers have made detailed explanations.In the past, many studies used plant carbonic anhydrase to capture CO2.Though this kind of carbonic anhydrase can survive in most environments,yet efficiency of human carbonic anhydrase for capturing CO2 is dozens of times higher than that of the plant one.<br>
| + | |
− | ③Q:The major scientific research direction of biochemical research center.<br>
| + | |
− | A:It can be concluded as drug delivery, CO2 capture and conversion, biomaterials and regenerative medicine. <br>
| + | |
− | ④Q:As far as we know, the carbonic anhydrase expressed in escherichia coli in our iGEM project is more active than that did in human body. This is because of the effect of modifying the active site based on the carbonic anhydrase expressed in human body. Therefore, we want to know how to find out the relevant active site to improve the activity of carbonic anhydrase by computer.<br>
| + | |
− | <div align="center"><img src="https://static.igem.org/mediawiki/2018/2/20/T--AHUT_China--_huagong2.jpg" width="300" height="300" alt=""/></div><br></p><p>
| + | |
− | A:The relevant active sites of carbonic anhydrase are known in the knowledge base. We use computer to simulate mutation of the known active sites of carbonic anhydrase to see if it can improve its function, which is verified by conducting relevant experiments later.Our workload and efficiency can be reduced and improved by computer simulation.<br>
| + | |
− | After that, Prof. Xu guided us to visit the molecular cells and experimental operation area in the biochemical research center.She showed us relevant experimental equipment and operation process, and then we used the enzyme marker to measure the absorbance and fluorescence of bacterial liquid under her guidance. We became more interested in biology and chemical engineering after this visit and the collaboration among our team members have been improved as well.<br></p>

| + | |
− | September 9, 2018, We arranged a video conference with members from northeastern university, Shandong University and northwestern University. During this time, we briefly introduced our project background and project ideas and planned the agenda of the Meeting. As the greenhouse effect has become a common concern in recent years, how to effectively capture carbon dioxide has become a worldwide problem. At present, carbon dioxide capture mainly includes absorption, adsorption and membrane method, these are high cost, renewable energy consumption and two times pollution problems. The use of CO2 to capture the high catalytic efficiency and environmental friendliness of the carbon anhydride has aroused wide concern,

− | <p>So our Anhui University of Technology team put forward a project on the generation of carbon anhydride through E. coli to absorb carbon dioxide. First of all, our project successfully expressed the Wide-type carbonic anhydride enzyme in Escherichia coli, however, due to its poor stability and ease of deactivation, its industrial applications were limited. Therefore, based on the molecular simulation technique, the effect of mutation of amino acid residues on the conformation and activity of enzymes was studied, and the mutant carbonic anhydride with high thermal stability was Obtained. The experimental results show that the purified mutant carbonic anhydride has higher stability and activity than the wild type of carbonic anhydride enzyme, which realizes the effective capture of CO2. Northeastern university, Shandong university, The members of Northwestern University have expressed their strong interest in our team project of Anhui University of technology, so we have the highlights of our project and other members of the school exchange, Highlights: 1, relative to the high cost, high efficiency and poor circulation of traditional methods, we choose high catalytic efficiency, low cost, A safe and environmentally friendly method for trapping CO2 with carbon anhydride. 2, using the molecular simulation technique, the amino acid as the basic unit, the effect of remnant radical mutation on the two-stage structure of the carbonic anhydride enzyme, and the influence of the molecular conformation, the best amino acid mutation site was obtained, and the thermal stability of the enzyme was improved without affecting the enzyme Activity. 3, we obtained the expression of wild type and mutant carbonic anhydride enzyme strains of Escherichia coli, and two kinds of carbon anhydride enzyme in vitro purification, wild-type carbonic anhydride enzyme has a certain CO2 capture efficiency, more importantly, the mutant than the wild type of carbonic anhydride enzyme has better stability and activity, realize the CO2 efficient capture.</p><br>

− | <p>Students from Tohoku University also briefed members of our other schools about their projects, and the Tohoku University project was inspired by the prevalence of fast food and the acceleration of urbanization, with the number of inflammatory bowel diseases (inflammatory bowel disease, IBD) Rising in asia, And the risk of developing colorectal cancer (colorectal cancer, CRC) in patients with IBD also increased. There are no drugs that are better for ibd, so they want to use engineered probiotics to treat IBD and prevent crc, using synthetic biology. The rest of us were very interested in the project, and our Anhui University of Technology team actively asked them for details about their project, and they briefed them on the project background and the project brief. The background of their project is that inflammatory bowel disease (IBD) is caused by inappropriate immune responses, which in general trigger a series of events that can disrupt the barrier when the immune system reacts excessively to the bacteria in the gut, eventually causing IBD when the immune imbalance persists without intervention. There is no cure for IBD at present, the best treatment now is to use anti-inflammatory drugs such as TNF inhibitor treatment, but the Patient's drug treatment effect is huge difference, to more than 50% of patients Ineffective. Probiotics are beneficial to the host of active microorganisms, colonization in the human intestinal tract, reproductive system, oral cavity and so can produce the exact health effects of the microbial group, has been beneficial to bacteria such as boulardii yeast used in clinical diarrhea Treatment. The Tohoku University team aims to design a biological system for ANTI-IBD and CRC prevention through the use of engineered Probiotics. Because the concentration of no in the intestinal tract of IBD is about 100 times times that of normal people, no molecule acts as their inflammatory signaling molecule, and probiotic Escherichia coli (nissle 1917) is selected as their chassis organism. The project consists of two sets of devices, one of which is an anti-inflammatory device, which includes a sensor for detecting inflammatory signals, a high-efficiency enhancer, and an effector that secretes interleukin (IL-10); the second is an anti-cancer device, which is expressed through engineered probiotics, which is derived from a cross-flowered vegetable ( Cruciferous vegetables (myrosinase), which converts the natural component of Thio-glucoside (sinigrin) from a cross-flowered vegetable into a turnip (sulforaphane), The product of radish is a kind of organic molecule with anticancer activity, and it can inhibit oxidative stress (oxidative stress), so it can also inhibit the intestinal inflammatory reaction. In addition, they use cold-shock kill switches (cold-excited expression lysis and Maz-ef) to prevent their engineered bacteria from escaping into the environment and causing DNA contamination.</p>

− | <p>Members of the Northwestern University team introduced their project background that saline soils may affect the growth of crops such as wheat and rice. Because traditional saline soils are difficult and inefficient, they have decided to address this global challenge in new ways. Several parts of the bacterium are designed to reduce the concentration within the Range. Their project is to modify potassium channels by using non-natural amino acid d-alanine, they obtained a new channel protein, which allows K + to be considered in a high concentration of K + and allows Na + to be considered in a low concentration of K +. Because of the use of d-ala, a part of the introduction of unnatural amino acids into bacteria was established. They analyzed proteins and tested them by molecular dynamics simulations and quantum chemistry, and established mathematical models of the relationship between cells and salt concentrates. They will use patch clamps and a new method to test proteins and bacteria in the Solution. After their cell experiments, they will use it for agricultural and water purification processes.</p>

− | <p> Microfluidics Technology refers to the technology of controlling, operating and detecting complex fluids at the micro size. It is a newly interdisciplinary subject developed on the basis of microelectronics, micromechanics, bioengineering and nanotechnology. The rapid development of Microfluidics Technology in recent years has stricken revolutionary impacts in the fields of chemistry, medicine and life science. Biochips are regarded as an important tool for interpretating gene sequences in the Post-Genome Era and microfluidics chips are also known as "lab-on-a-chip", which use MEMS (Micro Electro Mechanical Systems) technology for mixing the separated purification used in general laboratories and miniaturize devices such as enzyme reactions onto the chip for biochemical reactions, process control or analysis. The construction of this kind of chip is far more complex than microarray chips. According to ranges of its application, the chip can be further divided into three categories: sample pretreatment chip, reactive chip and analytical chip. They can perform complex and precise operations on microfluids (both liquid and gas), such as mixing and separation of microfluids, chemical reactions, microanalysis, etc. Besides, microfluidics chips also play a unique role in the screening of rare cells, the extraction and purification of MRNA, gene sequencing, single-cell analysis, and protein crystallization. They have been widely used in biotechnology research due to their lightweight, less sample or trial dose usage, fast reaction speed, large parallel processing and disposable features. </p><br>

− | This year, Harvard wants to work with other teams to end the misunderstanding of synthetic biology. We found that human exposure to bacteria tends to have negative effects, which considered as something dangerous. As an iGEM team, we understand that genetically engineered bacteria are largely untapped resources, helping us show the world the true potential of using such a bacteria for treatment, diagnosis, environment and more.Harvard plans to release a series of articles to show all the cool things and germs the team is working on. Besides, they want introductions of other teams’projects, so we send ours to them on request.

− | <p> Here is the introduction of our project. In the wake of the increasing greenhouse exerting more serious impacts on the global environment, the question of how to efficiently deal with CO2 is particularly critical. However, the traditional gas collection technology featured by high energy consumption and low efficiency is not yet mature enough. Meanwhile, it is these characteristics that have limited the development of itself.Our project is to obtain carbonic anhydrase (CA-2) with high thermal stability through computer simulation of the protein molecules expressed by carbonic anhydrase gene locus mutation, and import it into escherichia coli cells to achieve efficient collection of CO2.</p>

| + | |
− | <p>On August, 2018, our team established a connection with iGEM group of NEU-China-A and thus a couple of video conferences have been made so far. The two teams introduced each other's projects in detail; the project of NEU-China was to design a biological system against IBD and preventing CRC by using engineered probiotics. Since the concentration of NO in the intestines of IBD patients was about 100 times than that of normal people; therefore, NO molecules were chosen as inflammatory signals, and probiotics (Nissle 1917) were selected as chassis organisms. The project consisted of two sets of devices, one of which was an anti-inflammatory equipment, including a sensor for detecting inflammatory signals, an effective enhancers and an effector secreting interleukin 10 (il-10). Another one was an anti-cancer device, able to express a kind of myrosinase from cruciferous vegetables by virtue of engineering probiotics. Meanwhile, it can transfer glucosinolate, a natural ingredient in cruciferous vegetables into sulforaphane. Such a kind of product was a type of organic molecule with cancer-fighting ability and at the same time it could inhibit oxidative stress. Similarly, it could work against intestinal inflammation. In addition, we used cold shock kill switches (cold shock expression Lysis and maz-ef) to prevent our engineer bacteria from escaping into the environment and causing DNA contamination. </p>

− | During exchange of project experience with each other, we learned that NEU-China-A had a little bit problem in one of the plasmid insertion experiments, so they asked us for help and wanted us to conduct the construction experiment of secreting the yebf-homoil10 plasmid. We and our counterpart made it clear about what we were going to cooperate followed by three video meetings. NEU-China-A helped us carry out experiments on optimizing the conditions of prokaryotic expression of CSCA protein and purifying expression. In a similar way, we helped NEU-China-A perform fragment-linking experiment. NEU-China-A provided us with original plasmid of PCDF-Duet1 (dry powder tube), they taught us to overlap the secretion label Yebf (from BL21(DE3)DNA, GenBank: EF648003.1) with human-derived interleukin 10 (from BBa_K554004, Spring 2018 Distribution 21K 2018 Kit Plate 1), and required us to add the FLAG label at the N end of homoIL10 for subsequent protein detection. According to the requirements of our friend, we conducted the experiment on construction of secreting the plasmid Yebf-homoIL10. Having sequenced and verified the plasmid construction successfully, we mailed the no-less-than-100ng plasmid dry powder to them.
