DISSIMILATORY SULFATE REDUCTION BY VARIOUS DESULFOVIBRIO SP. STRAINS OF THE HUMAN INTESTINE

Microbiology&Biotechnology, 2013
The aim of this research was to study the dissimilatory sulfate reduction process by various Desulfovibrio sp. strains of the human intestine, such as bacterial growth, sulfate- and lactate usage, production of sulfide and acetate by the strains, and carry out cluster and correlation analyses of this process. Methods.

End Products of Anaerobic Chitin Degradation by Salt Marsh Bacteria as Substrates for Dissimilatory Sulfate Reduction and Methanogenesis [PDF]

Applied and Environmental Microbiology, 1986
The anaerobic pathway of chitin decomposition by chitinoclastic bacteria was examined with an emphasis on end product coupling to other salt marsh bacteria. Actively growing chitinoclastic bacterial isolates produced primarily acetate, H 2 , and CO 2 in broth culture.

Enriched iron(III)-reducing bacterial communities are shaped by carbon substrate and iron oxide mineralogy

Frontiers in Microbiology, 2012
Iron (Fe) oxides exist in a spectrum of structures in the environment, with ferrihydrite widely considered the most bioavailable phase. Yet, ferrihydrite is unstable and rapidly transforms to more crystalline Fe(III) oxides (e.g., goethite, hematite ...

Comparative Genomics and Proteomic Analysis of Assimilatory Sulfate Reduction Pathways in Anaerobic Methanotrophic Archaea

Frontiers in Microbiology, 2018
Sulfate is the predominant electron acceptor for anaerobic oxidation of methane (AOM) in marine sediments. This process is carried out by a syntrophic consortium of anaerobic methanotrophic archaea (ANME) and sulfate reducing bacteria (SRB) through an ...

The Role of DsrC in Dissimilatory Sulfite Reduction [PDF]

, 2015
Studies involving the human gastrointestinal microbiota and its metabolites have revealed the presence of sulfate-reducing bacteria (SRB) within the gut. These microorganisms have been implicated in inflammatory bowel diseases due to the toxic effects of

Deep-sea in situ and laboratory multi-omics provide insights into the sulfur assimilation of a deep-sea Chloroflexota bacterium

mBio
Chloroflexota bacteria are abundant and globally distributed in various deep-sea ecosystems. It has been reported based on metagenomics data that two deep-sea Chloroflexota lineages (the SAR202 group and Dehalococcoidia class) have the potential to drive

Bacterial enzymes for dissimilatory sulfate reduction in a marine microbial mat (Black Sea) mediating anaerobic oxidation of methane

, 2011
Anaerobic oxidation of methane (AOM) with sulfate is catalysed by microbial consortia of archaea and bacteria affiliating with methanogens and sulfate-reducing Deltaproteobacteria respectively.

Groundwater redox conditions at a petroleum contaminated site, Kuils River, South Africa : pathways for BTEX biodegradation

, 2003
Includes bibliographical references (leaves 84-88).A shallow sandy aquifer, contaminated by petrol from an underground storage tank, was studied to determine if intrinsic bioremediation of the hydrocarbons is taking place.

A novel mechanism for dissimilatory nitrate reduction to ammonium in Acididesulfobacillus acetoxydans

mSystems
The biological route of nitrate reduction has important implications for the bioavailability of nitrogen within ecosystems. Nitrate reduction via nitrite, either to ammonium (ammonification) or to nitrous oxide or dinitrogen (denitrification), determines

Regulation of anaerobic catabolism of aromatic compounds and sulfate reduction in Desulfobacula toluolica Tol2

, 2007
The metabolic regulation of the aromatic-compounds degrading sulfate-reducing bacteria Desulfobacula toluolica Tol2 in response to the availability and adaptation to aromatic growth substrates (toluene, phenylacetate, p-cresol, p-hydroxybenzaldehyde, p ...
