From 65438 to 0958, Professor Cheng Yuhua went abroad to study in Leningrad University, Soviet Union, and studied the frontier disciplines of biology in the world at that time-biochemistry, molecular biology and enzyme engineering. After returning to China, he founded the biology department and biochemistry specialty of Jilin University, and established the first national key laboratory in China-Enzyme Engineering Laboratory in Jilin University, which was the founder of enzyme engineering in China. Enzymatic hydrolysis technology, active enzyme culture and extraction technology all originated from Professor Cheng's research and guidance.
Enzyme engineering laboratory is located in Jilin University. Professor Cheng Yuhua is the director of the laboratory and Professor Zhang Longxiang is the director of the academic committee. The main academic leaders are Professor Cheng Yuhua, Associate Professor Zhang Jin, Associate Professor Cao Shugui, Associate Professor Luo Guimin and Associate Professor Zhang Xuezhong. The main research direction is the molecular modification and modification of enzymes, that is, the modification of enzyme molecules by biological, chemical or physical means. Change its physical and chemical properties and biological activity, so that it has better performance than natural enzymes. At the same time, research on new technologies and related basic theories of enzyme immobilization and enzyme stabilization will be carried out, which will make enzyme engineering develop in depth, expand its application in production and promote the formation of emerging industries.
From 65438 to 0984, Professor Cheng Yuhua was appointed as the first director of the Department of Molecular Biology, which was composed of biochemistry and molecular biology.
1999 14 In September, Professor Cheng Yuhua used his academic expertise and exquisite and advanced technology in the laboratory to apply for a patent for China Rana chensinensis eggs, a necessity of human life, and its application. The ancients have long recognized the nourishing and medicinal value of China Rana chensinensis, which can be proved by the records in all kinds of medical classics. It is a precious medicinal material with a long history and is recognized as the king of tonics. Known as "green soft gold" in the medical field.
1997 Jilin University established the College of Life Sciences according to the needs of discipline development.
On September 1 day, 2007, Professor Yu Hua published his autobiography A Journey in Winter and Spring, which was published by Jilin University Press. As a scientist, Cheng Yuhua fully respects science and facts. This book records a life of struggle and continuous progress in the form of memories.
