The effect of methanogenic archaea (Methanococcus maripaludis) on corrosion behavior of 316L stainless steel under different concentrations of organic electron donor (acetate) was investigated. The results showed that M. maripaludis can survive by utilizing 316L SS as an alternative energy source. The extracellular electron transfer from 316L SS relies on redox-active substances secreted by M. maripaludis. Corrosion of 316L SS is promoted along with decrease of acetate concentration. M. maripaludis causes severe pitting corrosion of 316L SS in the absence of acetate due to that more redox-active substances are secreted, which has little relationship with the M. maripaludis biofilm.
研究了产甲烷古菌（Methanococcus maripaludis）在不同浓度有机电子供体（乙酸盐）下对 316L 不锈钢腐蚀行为的影响。结果表明，M. maripaludis 可以利用 316L SS 作为替代能源存活。316L SS 的细胞外电子传递依赖于 M. maripaludis 分泌的氧化还原活性物质。随着乙酸盐浓度的降低，316L SS 的腐蚀加剧。由于分泌了更多的氧化还原活性物质，在没有乙酸盐的情况下，M. maripaludis 会导致 316L SS 发生严重的点蚀腐蚀，这与 M. maripaludis 生物膜关系不大。
