Monosaccharide and fatty acid composition of the exopolymer complex (EPC) of heterotrophic bacteria Pseudomonas pseudoalkaligenes 109, Pseudomonas sp. T/2, Rhodococcus erythropolis 102--destructors of the protective coating Polyken 980-25 has been studied. It is shown that qualitative and quantitative composition of EPC components changes depending on the model of bacteria growth. Arabinose, mannose, galactose and glucose are dominating saccharides. Xylose has been revealed only under conditions of the biofilm form of growth of all the studied bacteria; ribose only in the biofilm of Pseudomonas sp. T/2. The fatty acid composition of EPC contains saturated and unsaturated acids with 12-19 carbon atoms. Hexadecanoic acid (C 16:0) acid which content in the biofilm and plankton conditions is from 24.9 to 32.4% prevailed in the spectrum of fatty acids of EPC bacteria. Unsaturated fatty acids: hexadecanoic (C 16:1) and octadecenoic (C 18:1) ones have been revealed only in the biofilm of bacteria-destructors of the coating. |
