Studies on Collagenase of a Marine Bacterium:Part I. The Isolation and Determination of Microorganism Producing Collagenase

A marine bacterium, strain 7-246-6, isolated from sea water was found to elaborate aerobically an extracellular enzyme specific for native collagen and gelatin. The strain was identified as Pseudomonas marinoglutinosa from the morphological and physiological characteristics, though the strain 7-246-6 slightly differs from the latter in the following points; the shape of the colony on the plate culture, the optimum growth temperature, the presence of granule by granular staining, the utilization of carbohydrates and the number of flagellum.
