摘要：
A thermostable nitrilase producing isolate identified as Bacillus sp. MTCC 7545 has been studied towards production of nicotinic acid from 3-cyanopyridine. The benzonitrile was observed as inducer for the enzyme production. Maximum enzyme production was observed at 24 h of incubation and the activity of nitrilase was found to be optimum at 65 degrees C. The enzyme was stable for similar to 6 h at 50 degrees C. Besides pyridine-3 carbonitrile, benzonitrile was also a preferred substrate for the enzyme.
