中文摘要 | Many microbial species can use cathodes as electron donors for metabolism. This direct electron transfer (DET) pathway has rarely been proposed in biocorrosion processes. DET from Q235 carbon steel to the sulfate-reducing bacteria (SRB) Desulfovibrio caledoniensis and its effect on the corrosion behavior of carbon steel were investigated in the present study. Electroactive SRB biofilm was found to play a key role in the ennoblement of the corrosion potential (E-corr) and in the acceleration of the corrosion rate, indicating that SRB mainly affected the cathodic reaction of low carbon steel corrosion. In addition, SRB biofilm obtained electrons from carbon steel electrode polarized at -0.74 V. These findings present new evidence for DET between SRB biofilm and carbon steels. (C) 2012 Elsevier B.V.
