Covalent immobilization of D-aminoacylase of strain Rhodococcus armeniensis AM6.1 and the characteristics of the biocatalyst

Abstract

Immobilization of D-aminoacylase of the strain Rhodococcus armeniensis AM6.1 was carried out on the silochrome C-80 with a yield of enzymatic activity of 20%. The temperature and pH optima, thermal stability and dependence of thermal stability on pH for free and immobilized enzymes were compared. The possibility of using free and immobilized D-aminoacylases to produce D-amino acids from their racemic mixtures was demonstrated.
