ABSTRACT:
The present invention relates to a process for producing acrylamide or methacrylamide utilizing microorganisms having a nitrilase activity. This process involves (1) utilizing highly active novel bacteria belonging to the genus Corynebacterium or the genus Nocardia, (2) conducting the reaction utilizing microorganisms having a nitrilase activity at temperatures as low as the freezing point of the medium to 15.degree. C. so as to conduct the reaction for a long period of time while maintaining a high concentration of acrylamide or methacrylamide, and (3) conducting the reaction according to a newly devised continuous column process to obtain a highly concentrated acrylamide or methacrylamide aqueous solution with economic advantages.
