FIELD: biotechnologies.
SUBSTANCE: invention relates to recombinant bacterium strain Rhodococcus rhodochrous RNCIM Ac1960, which has a constitutive acylating activity and is obtained by replacement in a chromosome of strain Rhodococcus rhodochrous RCM Ac-1515D of a gene coding nitril hydrase with a gene coding acylamidase from strain Rhodococcus erythropolis 37 RNCIM Ac-1793, as well as to a synthesis method of N-replaced acrylamides from acrylamide and amines using it as a biocatalyst.
EFFECT: invention allows efficient production of concentrated solutions of N-replaced acrylamides.
