Some strains of B. cereus and B. anthracis produced a true collagenase which brought about complete disintegration of the collagen substrate, while strains of B. subtilis, B. licheniformis, B. brevis and B. megaterium were either completely inactive or produced only partial disintegration. Collagenase production was always accompanied by gelatinase production but the reverse was not the case. Concentrated culture filtrates of B. cereus were shown to contain collagenase and gelatinase whereas those of B. subtilis contained contained gelatinase only.", }
