  • Protease
    Patent number: 5312748
    Abstract: Novel alkaline serine proteases produced by Nocardiopsis sp. strains, for example by aerobic cultivation of strain 10R (NRRL-18262) and Nocardiopsis dassonvillei strain M58-1 (NRRL 18133), the proteases being characterized by a pH optimum of about 8, and by retention of at least 60% of maximum activity at pH 7-11 measured with casein as substrate.The proteases of the invention may be distinguished from the known protease of the Nocardiopsis strain ZIMET 43647 (of East German 2004328) and known Bacillus and fungal alkaline proteases. The Alkaline proteases of strains 10R and M58-1 may also be distinguished from each other.The protease preparations of this invention are useful detergent additives for cold water laundering.
