Phylogeny of sulfate-reducing bacteria1 [PDF]

open access: yesFEMS Microbiology Ecology, 2000
Sulfate-reducing bacteria (SRB) are a diverse group of prokaryotes that may be divided into four groups based on rRNA sequence analysis: Gram-negative mesophilic SRB; Gram-positive spore forming SRB; thermophilic bacterial SRB; and thermophilic archaeal SRB.

Sulfate-reducing bacteria and methanogens are involved in arsenic methylation and demethylation in paddy soils

open access: yesThe ISME Journal, 2019
Microbial arsenic (As) methylation and demethylation are important components of the As biogeochemical cycle. Arsenic methylation is enhanced under flooded conditions in paddy soils, producing mainly phytotoxic dimethylarsenate (DMAs) that can cause rice

Microscale sulfur cycling in the phototrophic pink berry consortia of the Sippewissett Salt Marsh [PDF]

open access: yes, 2014
Microbial metabolism is the engine that drives global biogeochemical cycles, yet many key transformations are carried out by microbial consortia over short spatiotemporal scales that elude detection by traditional analytical approaches.

The ability of sulfate-reducing bacteria Desulfovibrio desulfuricans Ya-11 i Desulfobacter sp. to use nitrate as electron acceptor

open access: yesБіологічні студії, 2011
The ability of Desulfovibrio desulfuricans Ya-11 bacteria to use nitrate as terminal electron acceptor was studied. The level of biomass accumulation in the medium with nitrate changed depending on the initial NO3– concentration. At nitrate concentration
