Diversity of Dissimilatory Sulfite Reductase Genes ( dsrAB ) in a Salt Marsh Impacted by Long-Term Acid Mine Drainage [PDF]

open access: yesApplied and Environmental Microbiology, 2010
ABSTRACT Sulfate-reducing bacteria (SRB) play a major role in the coupled biogeochemical cycling of sulfur and chalcophilic metal(loid)s. By implication, they can exert a strong influence on the speciation and mobility of multiple metal(loid) contaminants.

Sulfur Isotope Effects of Dissimilatory Sulfite Reductase

open access: yesFrontiers in Microbiology, 2015
The precise interpretation of environmental sulfur isotope records requires a quantitative understanding of the biochemical controls on sulfur isotope fractionation by the principle isotope-fractionating process within the S cycle, microbial sulfate ...

Environmental selection and evolutionary process jointly shape genomic and functional profiles of mangrove rhizosphere microbiomes

open access: yesmLife, 2023
Mangrove reforestation with introduced species has been an important strategy to restore mangrove ecosystem functioning. However, how such activities affect microbially driven methane (CH4), nitrogen (N), and sulfur (S) cycling of rhizosphere microbiomes

DIVERSITY OF SULFATE‐REDUCING GENES (dsrAB) IN SEDIMENTS FROM PUGET SOUND

open access: yesEnvironmental Technology, 2008
The aims of this study were to characterize the population structure and diversity of sulfate-reducing bacteria (SRB) from three distinct sites at Puget Sound, and relate the biogeochemical properties of the sediments to the sulfate-reducer communities.

Single-Cell Genome and Group-Specific dsrAB Sequencing Implicate Marine Members of the Class Dehalococcoidia (Phylum Chloroflexi) in Sulfur Cycling [PDF]

open access: yesmBio, 2016
The marine subsurface sediment biosphere is widely inhabited by bacteria affiliated with the class Dehalococcoidia (DEH), phylum Chloroflexi, and yet little is known regarding their metabolisms. In this report, genomic content from a single DEH cell (DEH-

Molecular analysis of microbial 16S rRNA, mcrA, dsrAB and pmoA genes from deep-sea hydrothermal vent and cold seep sites

open access: yes, 2008
Methane and sulfide are primary sources of energy supporting the dense macrobiological communities often found in cold seep areas and both free-living and symbiotic microorganisms depend on energy provided by the sharp gradient of sulfide and the reservoir of methane in the underlying sediments. In deep-sea hydrothermal vent areas, sulfide is typically

Microbial diversity in polluted harbor sediments II: Sulfate-reducing bacterial community assessment using terminal restriction fragment length polymorphism and clone library of dsrAB gene

open access: yesEstuarine, Coastal and Shelf Science, 2008
Sulfate-reducing bacteria (SRB) are important regulators of a variety of processes in coastal marine sediments regarding organic matter turnover, biodegradation of pollutants, and sulfur and carbon cycles. Yet their community compositions have not been investigated in polluted harbor sediments.

Microbial Metabolism and Disease Virulence Changes Across Day and Night in Coral Black Band Disease Lesions. [PDF]

open access: yesEnviron Microbiol
Metatranscriptomic reads from black band disease (BBD) lesions derived from samples collected during the day and night were mapped to near‐complete BBD‐derived metagenome‐assembled genomes to profile diurnal metabolic shifts among key microbial groups. Photosynthesis genes from the cyanobacterium Roseofilum reptotaenium were highly expressed during the

The Iron-Sulfur Flavoprotein DsrL as NAD(P)H:Acceptor Oxidoreductase in Oxidative and Reductive Dissimilatory Sulfur Metabolism

open access: yesFrontiers in Microbiology, 2020
DsrAB-type dissimilatory sulfite reductase is a key enzyme of microbial sulfur-dependent energy metabolism. Sulfur oxidizers also contain DsrL, which is essential for sulfur oxidation in Allochromatium vinosum.
