  • Protease from Dendryphiella arenaria DSM 6260 or Dendryphiella salina DSM 6332, process for making it and use as detergent additive
    Patent number: 5472865
    Abstract: A protease obtainable from Dendryphiella arenaria DSM 6260 or Dendryphiella salina DSM 6332 is disclosed. The protease has a pl of approximately 9.1 as determined by isoelectric focusing, a molecular weight of approximately 18-20 kD as determined by SDS-PAGE, is active towards haemoglobin, casein, skimmed milk, and Suc-Ala-Ala-Pro-Phe-pNA and has immunochemical properties identical to those of a protease obtained from Dendryphiella arenaria DSM 6260 or Dendryphiella salina DSM 6332. A process for its production, use in a detergent composition and as a detergent additive are disclosed.
    Type: Grant
