Gene clusters involved in anaerobic benzoate degradation of Geobacter metallireducens.
The degradation of aromatic compounds follows different biochemical principles in aerobic and anaerobic microorganisms. While aerobes dearomatize and cleave the aromatic ring by oxygenases, facultative anaerobes utilize an ATP-dependent ring reductase for the dearomatization of the activated key intermediate benzoyl-coenzyme A (CoA). In this work, the aromatic metabolism was studied in the obli...
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 کاملAnaerobic benzene oxidation via phenol in Geobacter metallireducens.
Anaerobic activation of benzene is expected to represent a novel biochemistry of environmental significance. Therefore, benzene metabolism was investigated in Geobacter metallireducens, the only genetically tractable organism known to anaerobically degrade benzene. Trace amounts (<0.5 μM) of phenol accumulated in cultures of Geobacter metallireducens anaerobically oxidizing benzene to carbon di...
متن کاملExpressing the Geobacter metallireducens PilA in Geobacter sulfurreducens Yields Pili with Exceptional Conductivity
The electrically conductive pili (e-pili) of Geobacter sulfurreducens serve as a model for a novel strategy for long-range extracellular electron transfer. e-pili are also a new class of bioelectronic materials. However, the only other Geobacter pili previously studied, which were from G. uraniireducens, were poorly conductive. In order to obtain more information on the range of pili conductivi...
متن کاملDirect interspecies electron transfer between Geobacter metallireducens and Methanosarcina barkeri.
Direct interspecies electron transfer (DIET) is potentially an effective form of syntrophy in methanogenic communities, but little is known about the diversity of methanogens capable of DIET. The ability of Methanosarcina barkeri to participate in DIET was evaluated in coculture with Geobacter metallireducens. Cocultures formed aggregates that shared electrons via DIET during the stoichiometric...
