PURPOSE:To obtain industrially useful amides having high purity from nitriles by using a microorganism belonging to the genus Xanthobacter and having ability capable of decomposing nitriles. CONSTITUTION:The objective amides are obtained from nitriles (preferably acrylonitrile) by using a microorganism belonging to the Xanthobacter and having ability capable of decomposing nitriles (preferably Xanthobacter flavus- JCM1204)). Preferably, the microorganism is cultured at 20-37 deg.C and pH5-10 for 1-7 days and then bacterial cells are collected from the cultured mixture and suspended in water, physiological saline, etc., and nitriles are added to the suspension to carry out the reaction by the bacterium. |
