Electron Transport in the Dissimilatory Iron Reducer, GS-15.
Mechanisms for electron transport to Fe(III) were investigated in GS-15, a novel anaerobic microorganism which can obtain energy for growth by coupling the complete oxidation of organic acids or aromatic compounds to the reduction of Fe(III) to Fe(II). The results indicate that Fe(III) reduction proceeds through a type b cytochrome and a membrane-bound Fe(III) reductase which is distinct from t...
متن کاملAnaerobic Oxidation of Toluene, Phenol, and p-Cresol by the Dissimilatory Iron-Reducing Organism, GS-15.
The dissimilatory Fe(III) reducer, GS-15, is the first microorganism known to couple the oxidation of aromatic compounds to the reduction of Fe(III) and the first example of a pure culture of any kind known to anaerobically oxidize an aromatic hydrocarbon, toluene. In this study, the metabolism of toluene, phenol, and p-cresol by GS-15 was investigated in more detail. GS-15 grew in an anaerobic...
متن کاملPhenol degradation in the strictly anaerobic iron-reducing bacterium Geobacter metallireducens GS-15.
Information on anaerobic phenol metabolism by physiological groups of bacteria other than nitrate reducers is scarce. We investigated phenol degradation in the strictly anaerobic iron-reducing deltaproteobacterium Geobacter metallireducens GS-15 using metabolite, transcriptome, proteome, and enzyme analyses. The results showed that the initial steps of phenol degradation are accomplished by phe...

متن کاملRole of humic-bound iron as an electron transfer agent in dissimilatory Fe(III) reduction.
The dissimilatory Fe(III) reducer Geobacter metallireducens reduced Fe(III) bound in humic substances, but the concentrations of Fe(III) in a wide range of highly purified humic substances were too low to account for a significant portion of the electron-accepting capacities of the humic substances. Furthermore, once reduced, the iron in humic substances could not transfer electrons to Fe(III) ...
