It was shown that sulfate-reducing bacteria developed on the sections of Kyiv municipal heating systems, which are exploited in conditions of different temperatures. The bacteria were different as to their morphological and physiological properties. The bacteria of Desulfovibrio genus were revealed on the sections, which were exploited at a temperature of 35-40 degrees C and bacteria of Desulfomicrobium and Desulfotomaculum genera were revealed on the sections with a higher temperature such as 60 degrees C. Based on of the 16S rRNA gene analysis data, it was demonstrated that sequences of TC2, TC3 and TC4 clones related to Desulfovibrio sp. DSM 12803 (100% sequence similarity), Desulfotomaculum sp. ECP-C-5 (92% sequence similarity) and Desulfomicrobium baculatum strain DSM 2555 (99% sequence similarity), respectively. The identified bacteria are potentially dangerous for heating systems and can be the agents of microbial corrosion.
结果表明，在基辅市供热系统不同温度条件下运行的管道截面上发现了硫酸盐还原菌。这些细菌在形态和生理特性上存在差异。在温度为35-40摄氏度的管道截面上发现了脱硫弧菌属的细菌，而在温度较高（如60摄氏度）的管道截面上发现了脱硫微菌属和脱硫肠状菌属的细菌。基于16S rRNA基因分析数据，结果表明，TC2、TC3和TC4克隆的序列分别与脱硫弧菌DSM 12803（序列相似性100%）、脱硫肠状菌ECP-C-5（序列相似性92%）和脱硫微菌DSM 2555菌株（序列相似性99%）相关。所鉴定出的细菌对供热系统具有潜在危险性，可能是微生物腐蚀的媒介。
