Research focus and objectives

1.Biomass enzymatic hydrolysis and conversion:Screen and identify new plant cell wall degrading microbial consortia and enzymes (xylanase, pectinase, etc.), clarify their regulation mechanism via enzyme kinetic and structural studies. Identify food functional ingredients bioconversion intestinal microbiota and enzymes, clarify the underlying catalytic mechanisms.

2.Microorganism breeding and engineering: Study on genetic improvement and gene editing technology of lactic acid bacteria. Engineering enzymes to produce valuable building blocks and integrating into different microorganisms for the synthesis of food bioactive components (vanillin, curcumin, etc.).

3.Functional fortified food development: Based on the domestically identified and studied enzymes and microorganisms (probiotics, etc.) to develop the bio-conversed functional fortified food.


1.New food enzyme screening, improvement and high-efficiency expression technology.

2.Vanillin biosynthesis technology and industrial application.

3.Study on key processing Technology of enzyme modified Cheese Powder.
