  • Lipases from hyphozyma
    Patent number: 5856163
    Abstract: A new species of the genus Hyphogyma is disclosed, as are new lipases obtainable therefrom, Also disclosed is a process for obtaining the enzymes.
    Type: Grant
    Filed: December 22, 1994
    Date of Patent: January 5, 1999
    Assignee: Novo Nordisk A/S

  • Alkaline lipases
    Patent number: 5763383
    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.
