Interest is the best teacher，It is also the source of motivation to improve yourself。This team is precisely because they share common scientific research interests，They just came together，After nearly two years of hard work，Together we completed this technological work。
Lingzhuo people，The team leader，2012 biotechnology student。I have shown strong interest in scientific research since entering freshman year，I chose Teacher Zhang Guoqing as my instructor at that time；Summer vacation of sophomore year，He dived into the laboratory and started a "lonely" life doing experiments，But I had a great time；In my junior year, I was able to help the instructor with some supplementary experiments，And started writing academic English papers。Wang Shounan，Formerly bet365 online sports betting mobilea student majoring in biotechnology in 2011，Currently a graduate student in 2015。He has a nearly persistent research interest in edible fungi，While serving as the president of the edible fungi club in the college，Not only did he learn the entire process of edible fungi cultivation，Apply the microbial knowledge learned in books to the cultivation and management of mushrooms，Lead members to practice the entire process of edible fungi production from mushroom stick preparation to fruiting management。May 2014，He founded Moshiwu Biotechnology Co., Ltd.，Under the guidance of teacher Zhang Guoqing，Introduced potted mushrooms、Gugu Energy Pack、Mushroom biological preparations、Mushroom Handmade Soap、Ganoderma lucidum and cordyceps pudding、Shuanger Runfei Decoction and other products，Developed a mushroom potting craft class、Yichi Farm Handicraft Class and many other parent-child interactive experience courses。As the instructor Zhang Guoqing said: "They are all enthusiastic about exploring scientific issues、Students with their own interests and practical abilities。I organized them together，Each perform their own advantages，Work together to complete the research。”
Project selection: familiar research field, practical research purpose
The "Challenge Cup" competition focuses on cultivating and creating an innovative practice system for college students' extracurricular students，On topic selection，Require college students to pay more attention to new fields、Research new issues、Use new methods、Create new results。Therefore，Participate in the College Challenge Cup，Topic selection is crucial。The team worked hard to choose a familiar research field when selecting the topic，Find the right practical research direction。The topic “Application of white rot laccase in dye degradation” belongs to the field of microbial research，It is the research field that the instructor Zhang Guoqing is familiar with。He has long been committed to teaching microbiology、Scientific research and technology promotion work，His research direction is the research and development of microbial bioactive substances、The promotion of edible fungus cultivation technology in the suburbs of Beijing is committed to the degradation of lignin in edible fungi、Anti-tumor、Lower blood bet365 online sports bettingsugar、Research on the isolation and development of anti-HIV biologically active substances，Laccase in fungi、Lectin、Protease、Many achievements have been made in research fields such as polysaccharides。Under the guidance of Teacher Zhang，Team members also have certain research in this field。
Choose your research field，It is necessary to determine the research direction or theme。How to make your research more practical，Better to solve practical problems。This is the main question that team members think about。
"Discovered after investigation，my country’s total dye production ranks first in the world，Dye wastewater will be generated during the production and use of dyes，Produce 1 ton of dye，Printing and dyeing consumes 1 ton of dye，Printing and dyeing consumes 1 ton of dye，10% is discharged with wastewater，These cause great pollution to water bodies。Thus endangering human health。The current dye wastewater treatment method only separates the dye from the water，Does not change the molecular structure of the dye，Easy to cause secondary pollution。If toxic dye molecules can be degraded into harmless small molecules from the perspective of biological enzymes，Avoid contamination transfer，Then this will be the most practical research。” Talking about the practicality of determining the research topic at that time，Team members are still very excited。Fungal laccase is one of the important functional proteins in the biodegradation of lignocellulose in nature，Dye at the same time、Environmental pollutants are degradable、Detoxification，has huge application development prospects。
Project Research: Be meticulous and meticulous, persist and persist
The most important step in research is to do experiments。What experiments require most is meticulousness and persistence。Sometimes a small factor can affect the entire experimental result。AndThe experimental requirements for microorganisms are even more stringent，A little carelessness can lead to infection of the vaccine，Once infected，The entire early efforts will be wasted。This situation occurred during the team’s nearly two years of experiments，Also experienced it。Once，The culture medium that the team cultured for seven days，Infectious bacteria during vaccination。This means the effort spent in seven days of experiments、Time vanished bet365 online sports betting mobileinto nothing。They had to start all over again。
It is inevitable to repeat the experiment during the experiment，But everyone in the team discovered the rare experimental changes and discoveries during the experiment，It is this kind of diligent pursuit、Perseverance，Their experiment achieved satisfactory results。
2014October to early 2015，The team including Ling Zhuoren and others began to write the paper under the guidance of teacher Zhang Guoqing，Based on smooth experiments and perfect experimental data，They completed a paper that is the envy of everyone。
2015May，Their scientific paper won the award。September 2015，At the same time, this scientific paper was published in "International journal of biological macromolecules》.
Knowledge link: Challenge Cup is the abbreviation of the "Challenge Cup" national series of scientific and technological academic competitions for college students，is provided by the Central Committee of the Communist Youth League、China Association for Science and Technology、Ministry of Education and All-China Federation of Students、A national extracurricular academic science and technology entrepreneurship competition for college students co-sponsored by local and provincial people's governments，The host university is a famous domestic university。The "Challenge Cup" competition has two parallel events in China，One is the "Challenge Cup" National College Student Extracurricular Academic Science and Technology Works Competition (Big Pick)；The other is the "Challenge Cup" Chinese College Students Entrepreneurship Plan Competition (Small Pick)。The national competitions for these two projects will be held in alternating order，Each project is held every two years。The "Challenge Cup" series of competitions is known as the "Olympics" event for Chinese college students' technological innovation and entrepreneurship，is currently the most popular national competition among domestic college students，Also the most representative in the country、Authority、Exemplary、Oriented college student competition。
