The selected BAY isolates were cultured at 37 ํC at 150 rpm in orbital shaker for enzyme production in basal salt media composed of KH2PO4 0.5 g, MgSO4 0.25 g , and gelatin 2 g, distilled water 1 L and containing Whatman filter paper No.1 (0.05 g/ 20mL) and at pH 6.8-7.2. Broth culture after six day of incubation period was subjected to centrifugation at 5000 rpm for 15 min at 4 ํC . The cells and other debris are settled down at the bottom and from the pellet. The cell free supernatant after centrifugation was collected and stored as crude enzyme preparation was further enzyme assays.
