The bacteria of Thiobacillus thioparus and Stenotrophomonas maltophilia are capable to form a thick biofilm complicated as to its structure on the surface of low-carbon steel. This biofilm formation on any surface occurs under the adhesion of the cells of the plankton growth model with the help of synthesis of muciferous exopolymers with adhesive properties. Hence the monosaccharide composition of the exopolymer complex in the form of polyol acetates was studied by chromate-mass-spectrum method. A significant difference in the composition of exopolymer monosaccharides with the presence of steel model in the medium and without it was established; a change in the monosaccharide composition of mono- and binary culture in the conditions of plankton and biofilm growth was also observed.
嗜硫硫杆菌和嗜麦芽窄食单胞菌能够在低碳钢表面形成结构复杂的厚生物膜。在浮游生长模式的细胞借助具有粘附特性的粘性胞外聚合物合成进行粘附的情况下，任何表面都会形成这种生物膜。因此，通过铬酸盐-质谱法研究了以多元醇醋酸酯形式存在的胞外聚合物复合物的单糖组成。确定了培养基中存在钢模型和不存在钢模型时胞外聚合物单糖组成的显著差异；还观察到在浮游和生物膜生长条件下单培养和双培养的单糖组成发生了变化。
