Two Rhodococcal isolates, one possessing a nitrile hydratase and an amidase enzyme, the other an aliphatic nitrilase enzyme have been isolated. The kinetic constants for the enzymes in each isolate have been determined. This data coupled with stability tests indicate that Rhodococcus ruber NCIMB 40757, the nitrilase containing organism, should be an excellent biocatalyst for the commercial production of ammonium acrylate. This is confirmed by a fed-batch bioconversion to produce 5.7 M ammonium acrylate.
