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

Environ 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

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

Applied 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.

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

Frontiers 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.

Phylogeography of Sulfate-Reducing Bacteria among Disturbed Sediments, Disclosed by Analysis of the Dissimilatory Sulfite Reductase Genes ( dsrAB ) [PDF]

Applied and Environmental Microbiology, 2005
ABSTRACT Sediment samples were collected worldwide from 16 locations on four continents (in New York, California, New Jersey, Virginia, Puerto Rico, Venezuela, Italy, Latvia, and South Korea) to assess the extent of the diversity and the distribution patterns of sulfate-reducing bacteria (SRB) in contaminated sediments.

Organic sulfur from source to sink in low‐sulfate Lake Superior

Limnology and Oceanography, Volume 68, Issue 12, Page 2716-2732, December 2023., 2023
Abstract Organic sulfur plays a crucial role in the biogeochemistry of aquatic sediments, especially in low sulfate (< 500 μM) environments like freshwater lakes and the Earth's early oceans. To better understand organic sulfur cycling in these systems, we followed organic sulfur in the sulfate‐poor (< 40 μM) iron‐rich (30–80 μM) sediments of Lake ...

Sulfur Isotope Effects of Dissimilatory Sulfite Reductase

Frontiers 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 ...

Validation of key sponge symbiont pathways using genome‐centric metatranscriptomics

Environmental Microbiology, Volume 25, Issue 12, Page 3207-3224, December 2023., 2023
The sponge microbiome is hypothesised to carry out a range of metabolic functions that improve the fitness of the host. Our study tested whether these metabolic functions were active across three different sponge species by analysing the gene‐expression of their symbionts.

Sulfidogenic Microbial Communities of the Uzen High-Temperature Oil Field in Kazakhstan

Microorganisms, 2021
Application of seawater for secondary oil recovery stimulates the development of sulfidogenic bacteria in the oil field leading to microbially influenced corrosion of steel equipment, oil souring, and environmental issues.
