To obtain information on the mechanism of microbiologically influenced corrosion (MIC) under anaerobic conditions, metabolic processes and microbial community dynamics were analysed for MIC of carbon steel with lake-mud microbial consortium as inoculum. During one month of MIC experiment, the microbial consortium corroded carbon steel with sulphate reduction, methane and acetate production. The bacterial and archaeal community structure in the suspension culture and the crust formed on carbon steel were compared using high-throughput Illumina MiSeq sequencing and quantitative polymerase chain reaction. The data indicated that sulphate-reducing bacterium (Desulfovibrio genus), amino acid-degrading bacterium (Aminobacterium genus) and a hydrogenotrophic methanogen Methanofollis among Archaea increased in the crust. These microbes were estimated to collaboratively induced corrosion of carbon steel under anaerobic condition.

为了获得有关在厌氧条件下微生物影响腐蚀（MIC）机理的信息，分析了以湖泥微生物联合体为接种体的碳钢的MIC的代谢过程和微生物群落动力学。在MIC实验的一个月中，微生物协会腐蚀了碳钢，并减少了硫酸盐的产生，甲烷和乙酸的产生。使用高通量Illumina MiSeq测序和定量聚合酶链反应，比较了悬浮培养物中的细菌和古细菌群落结构以及在碳钢上形成的外壳。数据表明，硫酸盐还原菌（Desulfovibrio属），氨基酸降解菌（Aminobacterium属）和氢营养型产甲烷菌古生菌中的甲硝唑含量增加。估计这些微生物在厌氧条件下协同诱导碳钢腐蚀。
