An enzymatic synthesis of N-substituted acrylamides (N-isopropyl acrylamide and N,N-dimethylaminopropyl acrylamide) has been demonstrated for the first time. The Rhodococcus erythropolis 37 strain possessing an acylamidase activity was used as a source of enzyme, whereas water-dissolved acrylamide and isopropylamine/dimethylaminopropylamine served as substrates. The optimum conditions for the synthesis of acrylamide N-substitutes were determined using N-isopropyl acrylamide. The maximum yield of the product was obtained at pH 9,5—10,5, ratio of the substrates (acrylamide/isopropylamine) 1,3;1—2:1 and absolute value of substrate concentration of 8,0% (acrylamide) and 4,0% (isopropylamine). Up to 22 g/l of N-isopropyl acrylamide was synthesized under the above conditions.


Key words:  acrylic monomers,  acylamidase,  biocatalyst,  N-isopropyl acrylamide,  Rhodococcus erythropolis.
