Sulfate/sulfite-reducing microorganisms (SRM) are ubiquitous in nature, driving the global sulfur cycle. A hallmark of SRM is dissimilatory sulfite reductase encoded by genes dsrAB. Based on analysis 950 mainly metagenome-derived dsrAB-carrying genomes, we redefine diversity with potential for sulfate/sulfite reduction and uncover genetic repertoires that challenge earlier generalizations regarding their mode energy metabolism. We show: (i) 19 out 23 bacterial 2 4 archaeal phyla harbor...
Sulfate-reducing microorganisms represent a globally important link between the sulfur and carbon cycles. Recent metagenomic surveys expanded diversity of putatively involved in sulfate reduction underscoring our incomplete understanding this functional guild. Here, we use genome-centric metatranscriptomics to study energy metabolism Acidobacteriota that carry genes for dissimilation compounds long-term continuous culture running under alternating anoxic oxic conditions. Differential gene...
An obligately anaerobic, spore-forming sulphate-reducing bacterium, strain SB140 T , was isolated from a long-term continuous enrichment culture that inoculated with peat soil an acidic fen. Cells were immotile, slightly curved rods stained Gram-negative. The optimum temperature for growth 28 °C. Strain grew at pH 4.0–7.5 of 6.0–7.0 using various electron donors and acceptors. Yeast extract, sugars, alcohols organic acids used as sulphate reduction. additionally elemental sulphur nitrate...
Summary Anaerobic digestion (AD) is an important technology for the effective conversion of waste and wastewater to methane. Here, syntrophic bacteria transfer molecular hydrogen (H 2 ), formate, or directly supply electrons (direct interspecies electron transfer, DIET) methanogens. Evidence accumulating that methanation short‐chain fatty acids can be enhanced by addition conductive material anaerobic digester, which has often been attributed stimulation DIET. Since little known about...
ABSTRACT Microbial degradation influences the quality of oil resources. The environmental factors that shape composition microbial communities are largely unknown because most samples from fields impacted by anthropogenic production, perturbing native ecosystem with exogenous fluids and microorganisms. We investigated relationship between formation water geochemistry community in undisturbed samples. isolated 43 microliter-sized droplets naturally enclosed heavy Pitch Lake, Trinidad Tobago....
Abstract Sulfate/sulfite-reducing microorganisms (SRM) are ubiquitous in nature, driving the global sulfur cycle. A hallmark of SRM is dissimilatory sulfite reductase encoded by paralogous genes dsrAB . Based on analysis 950 mainly metagenome-derived -encoding genomes, we redefine diversity with potential for sulfate/sulfite reduction and uncover genetic repertoires that challenge earlier generalizations regarding their mode energy metabolism. We show: (i) 19 out 23 bacterial 2 4 archaeal...
