Enzymatic hydrolysis of cell protein of Mononscus

To well utilize the cell filtered sediment of Mononscus,the enzymatic hydrolysis conditions for cell protein of Mononscus was studied.The optimum conditions were obtained as follows: neutral protease dosage 5.0×104U/g(cell amount),alkali protease dosage 7.0×104U/g(cell amount),enzymatic hydrolysis temperature 50℃,pH value 7.5,substrate concentration 40g/L and enzymatic hydrolysis time 18h.Under above optimal conditions,the degree of composite enzymatic hydrolysis was 10.60%,which was significantly higher than that of single enzymatic hydrolysis.
