Methanogens outcompete sulphate reducing bacteria for H2 in the human colon.

Methanogens outcompete sulphate reducing bacteria for H2 in the human colon.

Methanogens and sulphate reducing bacteria compete for H2 in the human colon, and, as a result, faeces usually contain high concentrations of just one of these two organisms. There is controversy over which of these organisms wins the competition for H2, although theoretical data suggest that sulphate reducing bacteria should predominate. To elucidate this question experiments were undertaken i...

Importance 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...

Sulphate 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., ...

The role of sulphate-reducing bacteria in oil recovery

Sulfate-reducing bacteria (SRB) are a group of microbes that use sulfate (SO4 ) as a final electron acceptor instead of oxygen for respiration (Al-Zuhair, El-Naas et al. 2008). SRB are able to use a very wide spectrum of different low molecular organic compounds (e.g. lactate, acetate, proprionate, succinate, pyruvate, ethanol, sugars, etc.) for growth, with SO4 being reduced to hydrogen sulfid...
