PRODUCTION OF FIBRINOLYTIC ENZYME (NATTOKINASE) FROM BACILLUS SP

During present study Nattokinase which is a novel fibrinolytic enzyme was produced by Bacillus sp. To screen and extract nattokinase enzyme from Bacillus sp. were isolated from soil of different agricultural field by serial dilution method. Out of 10 isolate, one strain i.e. B3 produced nattokinase on screening medium. B3 was identified by biochemical characterization. The caseinolytic activity of Nattokinase was 0.526 U/ml and the selected isolate Bacillus sp. could produce active nattokinase according to haemolytic activity 200 µl crude enzyme dissolve blood clot sample. Key Words: Bacillus sp., Caseinolytic Activity, Fibrinolytic enzyme, Haemolytic activity, Nattokinase.
