The microbiologically influenced corrosion of 201 stainless steel by was investigated via modulating the concentration of fumarate (electron acceptor) in the medium and constructing mutant strains induced by Δ. The ICP-MS and electrochemical tests showed that the presence of enhanced the degradation of the passive film; the lack of an electron acceptor further aggravated the effect and mainly affected the early stage of MIC. The electrochemical tests and atomic force microscopy characterization revealed that the ability of Δ to transfer electrons to the passive film was significantly reduced in the absence of the c-type cytochrome related to EET progress, leading to the lower corrosion rate of the steel.
通过调节培养基中富马酸盐（电子受体）的浓度并构建由Δ诱导的突变菌株，研究了201不锈钢的微生物影响腐蚀。电感耦合等离子体质谱（ICP-MS）和电化学测试表明， 的存在增强了钝化膜的降解；电子受体的缺乏进一步加剧了这种影响，并且主要影响微生物影响腐蚀（MIC）的早期阶段。电化学测试和原子力显微镜表征表明，在缺乏与胞外电子传递（EET）过程相关的c型细胞色素的情况下，Δ将电子转移到钝化膜的能力显著降低，导致钢的腐蚀速率降低。
