ABSTRACT:
A protease has been isolated from a symbiotic bacterium found in the gland of Deshayes of the marine shipworm. The protease remains active over the pH range of about 4-12, exhibits salt tolerance up to 3M sodium chloride, retains a high level of activity above 50.degree. C. for at least 60 min, and is stimulated by oxidizing agents, particularly perborate. The properties of this protease suggest widespread utility in detergents and other low-temperature industrial applications.
