BIOTECHNOLOGICAL METHOD OF OBTAINING ACRYLAMIDE Russian patent published in 2012 - IPC C12P13/02 C12N9/78 C12R1/01

Abstract RU 2468084 C1

FIELD: medicine.

SUBSTANCE: invention relates to biotechnology, in particular, to obtaining water solutions of acrylamide. Method is realised by hydration of acrylonitrile under action of water suspension of biocatalyst - strain of Rhodococcus rhodochrous M-8, possessing nitrile hydratase activity. Water suspension of biocatalyst contains stabilising additive, polyacrylic acid in amount 0.0015-0.015 wt % and disodium salt of ethylenediaminetetraacetic acid in amount 0.0005-0.003 wt % being used as such.

EFFECT: invention makes it possible to increase efficiency of biocatalyst action in obtaining target product, corresponding in quality to laid technical demands and to simplify the process.
