The main research fields of this group involve microbial enzymology, solid-state fermentation theory, marine natural products and environmental bioengineering. Since 1995, the research group has undertaken 25 national, provincial and municipal scientific research projects, including the research start-up fund for returned overseas students of the Ministry of Education 1 and the sub-project "Ocean 863 Project-Discovery of Active Lead Compounds from Marine Microorganisms"; Key Laboratory of Experimental Marine Biology, China Academy of Sciences 1 Project; German BMBF (Ministry of Science and Education) key project "Research on Marine Functional Substances" sub-project1; Anhui Outstanding Youth Fund 1 item, Anhui Natural Science Fund 4 items. 4 natural science foundation projects of Anhui Provincial Department of Education; Key scientific research projects in Anhui province 1 project; Anhui Science and Technology Department 1 Key Scientific Research Project; Anhui International Science and Technology Cooperation Project 1 each, Hefei Key Scientific Research Project 1 each; There are many scientific research projects at the school level. In the research of microbial enzymes, our class has developed microbial xylanase, amylase, chitinase and lipase, fucoidanase, β -glucanase and other enzyme preparations. We have accumulated a lot of experience in the research of enzyme preparation, obtained two patents, successfully screened xylanase-producing bacteria with industrial application prospects, and successfully produced crude enzyme powder, freeze-dried enzyme powder and liquid enzyme preparation. The technology of enzyme preparation production and xylooligosaccharide production is in the stage of technology transfer. * * * Postgraduates have been trained 1 1 person, of which 3 have graduated (2 with Universities of Applied Sciences in G? ttingen, 2 with Lanzhou University and Institute of Oceanography of Chinese Academy of Sciences 1 person), and 7 with Hefei University of Technology and Anhui Agricultural University.
