摘要：
It is known that proteinase biosynthesis is influenced by the conditions of a producer's cultivation. We show that enzyme production is 5 times higher on the medium with pH 7.7 than on the medium with pH 8.5 traditionally used for biosynthesis of many hydrolytic enzymes, including proteinases of initial strain of B. intermedius 3-19 and recombinant strains of B. subtilis AJ73. Maximum efficiency of recombinant strain in terms of the synthesis of glutamyl endopeptidase is observed with a medium volume to flask volume ratio of 1 : 4.
