WebThe UV absorbance spectrum of F430-3 was different from that of F430 and instead matched that of an F430 deriv. where the 173 keto moiety had been reduced. This is the first report of a modified F430 in methanogens. In a search for F430-2 and F430-3 in other methanogens and ANME, the authors have identified a total of nine modified F430 … WebThe mechanism of Fe 0 oxidation is cathodic depolarization, in which electrons from Fe 0 and H + from water produce H 2, which is then released for use by the methanogens; thermodynamic calculations show that significant Fe 0 oxidation will not occur in the absence of H 2 consumption by the methanogens. The data suggest that methanogens …
