    • The microorganisms were cultured in a 250 mL flask containing 100 mL of medium at 30°C in rotatory shaker (200 rpm). After 60 h substrate was added (20 mg) in DMF (0.2 mL) and the incubations were maintained at 30°C with orbital shaking and samples (1 mL) were withdrawn in 24 h intervals. Biomass was sedimented (15 min, 13,500 rpm), supernanants were micro-filtered (0.45 μm) and the filtrates were analyzed by HPLC
