Abstract
Mutants of B. subtilis A-50 capable of sporulating in the medium containing 5% glucose are isolated. The mutants are divided into 3 groups. The 1st group consists of glur mutants whose level of proteolytic activity is lower than that of the initial strain A-50. The productivity of mutants of the 2nd group is equal to the level of alkaline proteinase synthesizing characteristics of the original strain. In mutants of the 3rd group the level of alkaline protease synthesis exceeds the productivity of the initial strain. No correlation exists between the efficiency of spore formation in the mutants and the level of alkaline protease activity. The mutants of different groups differ in their ability to grow on different sugars.
