Proteolytic mutants were isolated from toxigenic strains of Clostridium botulinum type E after several transfers. When these cultures were plated on blood agar, almost all of the colonies obtained were proteolytic, and there were fewer toxigenic colonies than nontoxigenic colonies. The proteolytic mutants and nonproteolytic original strains were different in their biological properties.
