Microbial pathways of sulfur metabolism and colorectal cancer risk
… (SRB), dissimilatory sulfate reductase (pan-dsrA), Bilophila wadsworthia-specific dsrA, and 16S rRNA genes for Desulfobacter spp., Desulfovibrio spp., and Desulfotomaculum spp.. Bilophila wadsworthia-specific dsrA was more abundant in AA cases compared to AA controls (p<0.001). Linear …

Influence of Petroleum Deposit Geometry on Local Gradient of Electron Acceptors and Microbial Catabolic Potential
… via quantitative polymerase chain reaction of dsrA (sulfate-reduction), mcrA (methanogenesis), and cat23 (oxygenation of aromatics) genes in column cores suggested more extensive anaerobic conditions induced by the sheet relative to the ball geometry. Denaturing gradient gel electrophoresis …

A small RNA regulates RpoS in the Lyme disease spirochete Borrelia burgdorferi
… identified and characterized the first sRNA, DsrABb, in the Lyme disease spirochete, <em>Borrelia burgdorferi</em>; as well as, identified a non-canonical RNA chaperone Hfq. The alternative sigma factor RpoS (sigma 38 or sigma S) plays a central role in the reciprocal regulation of the …

Comparative analysis of primate hydrogenotrophic microbiota
… quantitative real-time PCR targeting mcrA and dsrA genes. Functionality of methanogens was determined by detection of methane from in vitro incubation of fresh feces. The results showed that the host species-specific hydrogenotrophic microbiota can be observed in some, but not all, of the …

Distribution of Dehalococcoidia in marine sediments and strategies for their enrichment
… for the presence of sulphate reduction (highest dsrA gene copies and a decrease in sulphate concentration in its pore-waters). On the other hand, the basin area was comparably poor in organic matter with high concentrations of iron(II) and manganese(II) in its pore-waters. Dehalococcoidia were …
