In order to study the practicability of enzymatic product(EP) of soybean protein(SP)using double enzymatic hydrolysis in enhancement of microbial growth and fermentation,SP was hydrolyzed by 2709 alkaline proteinase and neutral cellulase,and dried and ground and added to medium.By inoculating,phenomenon of microbial growth and fermentation were witnessed compared with commercial peptone(CPT).Hydrolytic product of SP using double enzymes may be a potential sources to enhance the growth and fermentation of microorganisms.It pointed out that the product ca...
