RESUMO
The nitrilase which occurs abundantly in cells of Rhodococcus rhodochrous J1 catalyzes the direct hydrolysis of 3-cyanopyridine to nicotinic acid without forming nicotinamide. By using resting cells, the reaction conditions for nicotinic acid production were optimized. Under the optimum conditions, 100% of the added 3-cyanopyridine could be converted to nicotinic acid, the highest yield achieved being 172 mg of nicotinic acid per 1.0 ml of reaction mixture containing 2.89 mg (dry weight) of cells in 26 h.
