On the other hand, the possibility that SOC decomposition is regulated by dissimilatory
Fe reduction processes should not be ignored (Dubinsky et al.
They also isolated two new strains of dissimilatory
Fe-reducing bacteria and supported the hypothesis that dissimilatory
iron reduction is an important biogeochemical process in the environment .
reduction of arsenic(V) to arsenic (III) in anoxic sediments.
SRB corrosion involves a number of chemical entities such as hydrogen sulfide and bisulfide anions (resulting from the dissimilatory
reduction of sulfate anions by bacteria) and metastable sulphur compounds like thiosulfate and polythionates.
Among specific topics are microbial ecology in extreme acidic pit lakes of the Aberian Pyrite Belt in southwestern Spain, galactose as an inducer of the production of extracellular polymeric substances by Acidithiobacillus ferrooxidans, evidence for widespread dissimilatory
hydrogen metabolism among acidophilic bacteria, immobilizing new isolated iron oxidizing bacteria on natural carriers, and the influence of pyrite on the galvanic assisted leaching of chalcocite concentrates.
The change, a dissimilatory
process, was effected through the lowering of the first segment of the diphthong.
The existence of low nitrate concentrations in groundwater samples with high levels of ammonium suggests the occurrence of dissimilatory
nitrate reduction (Thayalakumaran et al.
Pore-fluid iron isotope measurements have so far been restricted to the continental shelves where the supply of carbon is typically high and dissimilatory
iron reduction is extensive, precluding comparisons with low-carbon, deep-water environments.
2006) recently constructed a genome-scale metabolic model of metabolism in the dissimilatory
Fe(III) reduction with the objective of improved understanding of this unique mode of metabolism.
This is, however, harder to show, given the wide range of dissimilatory
processes that are frequently grouped together (see Suzuki 1998).

Under the alternation of anoxic/anaerobic conditions, the nitrogen cycle of wetland ecosystems catalysed by microorganisms includes di-nitrogen fixation, nitrification, denitrification, ammonification, anaerobic ammonium oxidising (anammox), and dissimilatory
nitrate reduction to ammonium (Purvaja et al.
Besides, hydrogen sulfide is produced in the large intestine by a dissimilatory
sulfate reduction, which has higher affinity for hydrogen and a lower hydrogen threshold than methanogenesis if a sufficient amount of sulfate is supplied (Zinder, 1993).
1996), denitrification (Tiedje 1988; Firestone and Davidson 1989), and dissimilatory
