ABSTRACT:
There are described, normally sporulating mutant Bacillus strain(s) which produce no detectable proteolytic activity during any phase of its growth. The absence of detectable proteolytic activity is due to the deletion of one or more codons specifying the mature subtilisin protease and the mature neutral protease. Also described are methods for producing such normally sporulating, protease deficient Bacillus mutants.
