    摘要: 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.

    摘要: A bacteriolytic enzyme complex is obtained from a bacterial culture of Bacillus pabuli strains, e.g. , isolates 350-2 (NRRL B-18446) and 391-1 (NRRL B-18447). This bacteriolytic enzyme complex is useful as an antibacterial agent against both Gram-positive and Gram-negative bacteria. The enzyme complex may be produced by cultivating the B. pabuli microorganisms in an aqueous medium containing cornsteep liquor, after which the lyric enzyme complex can be recovered from the fermentation broth.
