2. Environmental Microbiology (Microbes and Sewage Treatment) Microbes and Clean Energy Research Direction
Ethanol production from lignocellulose: With the world energy crisis, the increase of car ownership and the increasingly serious environmental pollution, the development and utilization of renewable energy is a hot spot in the world today. In 2005, China imported 654.38+0.2 billion tons of oil, which seriously threatened the national energy security. The state attaches great importance to the research and development of renewable energy. Producing fuel ethanol from lignocellulose is one of the main ways to replace traditional fossil energy. The research direction mainly focuses on lignocellulose hydrolysis and ethanol fermentation, exploring the hydrolysis pathway of lignocellulose with high sugar concentration and low fermentation inhibitor concentration, as well as efficient ethanol fermentation strains and fermentation technology.
Construction of recombinant bacteria and recombinant Saccharomyces cerevisiae: In the pretreatment and hydrolysis of lignocellulose, pentose and glucose can be fermented into ethanol. Traditional ethanol fermentation strains, such as Saccharomyces cerevisiae and Zymomonas mobilis, can only metabolize six-carbon sugars to produce ethanol, and 30% of xylose produced by lignocellulose hydrolysis cannot be converted into ethanol. Therefore, it is of great theoretical and practical significance to construct a recombinant strain that can metabolize xylose and glucose to produce ethanol.
Biodiesel produced by microorganisms: Diesel is an important fuel. In order to alleviate oil shortage, reduce environmental pollution and reduce carbon dioxide emissions, biological production of biodiesel is an important way to replace diesel. Oil-producing plants, oil-producing algae and oil-producing microorganisms can be used to produce biodiesel. This direction is to study the types and characteristics of oil-producing microorganisms, transform oil-producing microorganisms with genetic engineering technology, and improve microbial oil recovery efficiency. Research direction of environmental microbiology
Microbiology and wastewater treatment: this direction is mainly engaged in laboratory research on microbiology, biochemistry and water treatment technology of microbial wastewater treatment, including the principles and technologies of nitrogen and phosphorus removal in high-concentration organic wastewater, toxic wastewater and wastewater treatment, and the research results guide pilot-scale and production-scale application.
