Abstract

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.

摘要

对防护涂层破坏菌假单胞菌属T/、假单胞菌属109、节杆菌属102的胞外聚合物复合物（EPC）的单糖组成进行了研究。已确定细菌胞外聚合物复合物的单糖组成不同，且取决于细菌的生长模式。其主要由戊糖和己糖组成。在所有研究细菌的生物膜和浮游生物的EPC中检测到的葡萄糖、半乳糖、阿拉伯糖是主要的单糖。生物膜中葡萄糖含量为22.6%至39%；半乳糖为17%至26.4%；阿拉伯糖为0.4%至31.6%。所研究的细菌也合成甘露糖，但数量比其他单糖少。在假单胞菌属st.109的EPC中发现了核糖，木糖存在于所有研究细菌的EPC生物膜中。
