Abstract The effect of sulphur compounds and temperature on the microbiologically influenced corrosion of carbon steel has been assessed using multispecies biofilms. Biofilm composition, community structure and activity level shifted in response to environmental conditions, which resulted in substantial differences in pitting susceptibility of carbon steel. Microorganisms enhanced pitting when sulphur compounds were available, but there was not a distinctive pattern on the effect of temperature. In average, old biofilms caused greater pitting than young biofilms. Functional profiles predicted from 16S rRNA data revealed that biofilms had similar capabilities regardless of environmental conditions and the extent of corrosion associated with them.

作为环境条件函数的微生物影响腐蚀：使用油田多物种生物膜的实验室研究

摘要 使用多物种生物膜评估了硫化合物和温度对碳钢微生物腐蚀的影响。生物膜组成、群落结构和活性水平随着环境条件的变化而变化，导致碳钢点蚀敏感性存在显着差异。当硫化合物可用时，微生物会增强点蚀，但温度的影响没有明显的模式。平均而言，旧的生物膜比新的生物膜引起更多的点蚀。从 16S rRNA 数据预测的功能概况表明，无论环境条件和与之相关的腐蚀程度如何，生物膜都具有相似的功能。
