腐乳产蛋白酶菌种的筛选

Screening the Proteinase Strain from the Fermented Bean Curd

采用2种不同的培养基,对4种不同品牌腐乳产蛋白酶的菌株进行了筛选,从每种腐乳中筛选出了1株透明圈与沉淀圈比值较大的菌株,研究了它在发酵过程中蛋白酶活力的变化。

In this paper, two kinds of different culture medium was used to screen the four kind of different brand fermented bean curd which can produce the proteinase, each kind of fermented bean curd was screened one strain to produces the biggest proteinase and studied the change of enzyme vigor in its fermentative process.
