Evaluating the importance of flavin-based electron shuttling in corrosion
Source abstract
Abstract
Faster microbial corrosion of ferrous metals with flavin amendments has led to the common perception that flavins function as an electron shuttle for extracellular metal-to-microbe electron transfer . Direct examination of this possibility revealed that electron transfer from Fe 0 or X80 carbon steel to flavins or the humic acid analogue anthraquinone-2,6-disulfonate (AQDS) was orders of magnitude slower than proton reduction to H 2 . Stainless steel did not reduce shuttles. Electron shuttles could not serve as the electron donor for sulfate reduction. Riboflavin enhanced Desulfovibrio vulgaris growth on H 2 , suggesting that the primary impact of added flavins is acting as a nutrient.
