[Monosaccharide composition of exopolymer complex of bacteria-destructors of protective coatings].

Monosaccharide composition of exopolymer complex (EPC) ofbacteria-destructors of protective coatings Pseudomonas sp. T/, Pseudomonas sp. 109, Arthrobacter sp. 102 has been studied. It is established that monosaccharide composition of exopolymer complex of bacteria is different and depends on the bacteria growth model. It is mainly represented by penthoses and hexoses. Glucose, galactose, arabinose, which are determined in EPC of biofilm and plankton of all studied bacteria, are dominating monosaccharides. Glucose content in the biofilm is from 22.6% to 39%; galactose--from 17% to 26.4%; arabinose--from 0.4 to 31.6%. Mannose is also synthesized by the studied bacteria, but in less quantity than other monosaccharides. Rhibose is found in EPC of Pseudomonas sp. st. 109, xylose--EPC biofilm of all studied bacteria.
