Collagenase production by Achromobacter iophagus.
Achromobacter iophagus produced collagenase (EC 3.4.24.3) when cultured aerobically in buffer containing 5% peptone. The bacterium is non-pathogenic and tests on rabbits indicated that the culture medium was atoxic. The collagenase, which hydrolyzed insoluble and soluble native collagen, was purified by (NH4)2 SO4 precipitation, starch block electrophoresis, and gel filtration. It was shown to be serologically distinct from Clostridium histolyticum collagenase and to have molecular weight and sedimentation coefficient values of approx. 112 000 and 5.3 S, respectively.
