[Mutants of Bacillus subtilis--producer of alkaline proteinase, sporulating in the presence of high concentrations of glucose].

Glur mutants of Bacillus subtilis A-50 capable of sporulating in the medium containing 5% glucose are isolated. The mutants are divided into three groups. The first group comprises 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 synthesis characteristics of the original strain. In mutants of the third group the level of alkaline protease synthesis exceeds the productivity of the initial strain. There was no correlation between the efficiency of spore formation in the mutants obtained and the level of alkaline protease activity. The mutants of different groups differ in their ability to grow on different sugars.
