Immobilization of cells of nitrile-hydrolyzing bacteria Rhodococcus erythropolis 4-1 and Alcaligenes faecalis 2 using thermotropic and ionotropic gels

Cells of amidase containing bacteria of Rhodococcus erythropolis 4-1 and Alcaligenes faecalis 2 were immobilized using carriers such as barium alginate, agarose, chitosan and к-carrageenan. The aim of the work was to study the effect of bacterial cell immobilization methods on the operational stability of a biocatalyst. It has been determined that the best carrier for the stable operation of the biocatalyst was agarose. The highest amount of acrylic acid was obtained during multi-cycle transformation of acrylamide by immobilized A. faecalis 2 cells.
