Microbial nitrilases are biocatalysts of industrial interest and being used for the production of amides and acids from their respective nitriles. The production of nitrilases from various sources has been reported with specific catalytic properties at flask level. We attempted the nitrilase production from a Streptomyces sp. MTCC 7546 in a lab scale stirred tank bioreactor under various physiological conditions. The effect of temperature, inducer concentration, agitation, cultivation time and aeration respectively were optimized and it was found that benzonitrile at a concentration of 10 mM, aeration rate in the range of 0.7-1.0 vvm and an agitation of 200 rpm were most suitable conditions for maximum synthesis of intracellular nitrilase. At optimal conditions, the produced dry cell biomass and the productivity of the process were 10.26 g/L and 0.43 g/L/h repectively.
