title: [Biotransformation of organic substances by an immobilized associative bacterial culture].
abstract: Bacterial strains were screened to transform to end-products (carbon monoxide and water) elevated concentrations of acetone, acidic acid, and ethanol in a biocatalyst with an immobilized bacterial association cultivated on solid foam polyvinyl acetate (FPVA). The innocuous association amalgamated Paracoccus denitrificans VKM V-1324, Pseudomonas esterophilus VKM V-1736D and Achromobacter parvulus VKM V-1541D. The biocatalyst was tested with the help of classic methods and equipment for microbes cultivation. Microbial growth was assessed in the optical density units. Comparative evaluation of the biocatalytic activity was performed on gas-chromatographer Pue Unicam-104. Based on test results, specific rates of oxidation of acidic acid, ethanol and acetone per one g of FPVA were 0.75, 0.72, and 0.67 mg/hr, respectively.
