Abstract
A highly alkaline, positionally non-specific lipase can be obtained from the strains of streptomyces, cluster 1. Strains of cluster 1 of Streptomyces were not previously known to produce lipase. The lipase preparation has more than 50% of its optimum activity at pH 10 and is useful, e.g. in detergents.
