Electron uptake by iron-oxidizing phototrophic bacteria.
Oxidation-reduction reactions underlie energy generation in nearly all life forms. Although most organisms use soluble oxidants and reductants, some microbes can access solid-phase materials as electron-acceptors or -donors via extracellular electron transfer. Many studies have focused on the reduction of solid-phase oxidants. Far less is known about electron uptake via microbial extracellular ...
متن کاملInfluence of hydrogen-oxidizing bacteria on the corrosion of low carbon steel: Local electrochemical investigations.
Low carbon steel has been considered a suitable material for component of the multi-barrier system employed on the geological disposal of high-level radioactive waste (HLW). A non negligible amount of dihydrogen (H2) is expected to be produced over the years within the geological repository due to the anoxic corrosion of metallic materials and also to the water radiolysis. The influence of the ...
متن کاملImportance of Sulphate-reducing Bacteria in Environment
The sulphate-reducing bacteria represent the part of the biosphere, the active component in the cycle of elements in the biosphere and as shown by the existing knowledge they are becoming also the part of the environmental industrial technologies. The objective of this work was to give principal information concerning characteristics, the occurrence and the importance of sulphate-reducing bacte...
متن کاملGrowth kinetics of attached iron-oxidizing bacteria.
A model of growth and substrate utilization for ferrous-iron-oxidizing bacteria attached to the disks of a rotating biological contactor was developed and tested. The model describes attached bacterial growth as a saturation function in which the rate of substrate utilization is determined by a maximum substrate oxidation rate constant (P), a half-saturation constant (K(s)), and the concentrati...
متن کاملSulphate Reducing Bacteria and Mackinawite Stability
Introduction: The formation of sedimentary iron monosulphides (mackinawite, greigite) and pyrite is strongly interlinked with bacterial sulphate reduction, and thus with the global geochemical Fe, S and C cycles [1, 2]. The inorganic formation and stability of FeS phases at T < 100 ̊C has been extensively studied due to their vital importance in the sedimentary pyrite formation processes [e.g., ...
