The purpose of the research has been the development and utilization of preparation about the new immobilized carrier with Auricularia gel and made it as the carrier of the immobilized alkaline protease,then established a fixed model.

Then the immobilized alkaline protease were characterized and the hydrolysis condition of wheat germ protein with it were optimized.

Study on active peptides preparation by immobilized trypsin;

Immobilized trypsin with compound silica;

Study on the breeding of highly producing strain of alkaline protease and its solid-state fermentation conditions;

Extraction and characterization of crude alkaline proteases from intestine of grass carp(Ctenopharyngodon idellus);

Fermentation conditions of alkaline protease from marine bacterium strain 15E(Brevibacterium oxydans);
