Cadmium resistance (0.1 to 1.0 mM) was studied in four pure and one mixed culture of sulfate-reducing bacteria (SRB). The growth of the bacteria was monitored with respect to carbon source (lactate) oxidation and sulfate reduction in the presence of various concentrations of cadmium chloride. Two strains Desulfovibrio desulfuricans DSM 1926 and Desulfococcus multivorans DSM 2059 showed the high...

Biogeochemical transformations occurring in the anoxic zones of stratified sedimentary microbial communities can profoundly influence the isotopic and organic signatures preserved in the fossil record. Accordingly, we have determined carbon isotope discrimination that is associated with both heterotrophic and lithotrophic growth of pure cultures of sulfate-reducing bacteria (SRB). For heterotro...

This paper clarifies the causes of a corrosion process observed in austenitic stainless-steel pipes, grade 316L, used for conducting freshwater port area. During pressure test installation, before it was put into service, about five months after its construction, loss detected due to leaks fluid contained and presence damage on wall tubes, some cases even passing through thickness tube. An anal...

A gutless polychaete of the family Siboglinidae, Oligobrachia mashikoi, known in the past as a beard worm of the group Pogonophora, inhabits Tsukumo Bay of the Noto Peninsula in the Sea of Japan. Photographs were taken of this polychaete projecting about one third of the length of its tentacles outside of its tube. The tube protruded several mm from the sea bottom. These are the first field pho...

Spore-forming, Gram-positive sulfate-reducing bacteria (SRB) represent a group of SRB that dominates the deep subsurface as well as niches in which resistance to oxygen and dessication is an advantage. Desulfotomaculum reducens strain MI-1 is one of the few cultured representatives of that group with a complete genome sequence available. The metabolic versatility of this organism is reflected i...

Sulfate-reducing bacteria (SRB) are anaerobic that form biofilm and induce corrosion on various material surfaces. The quorum sensing (QS) system employs acyl homoserine lactone (AHL)-type QS molecules primarily govern formation. Studies SRB have reported the presence of AHL, but no AHL synthase been annotated in so far. In this computational study, we used a combination data mining, multiple s...

The monitoring of trace metals in microbial cells is relevant for diagnosis inflammatory bowel disease (IBD). Sulfate-reducing bacteria (SRB) represent an important factor the IBD development. content bacterial may reflect functioning enzyme systems and environmental impact on occurrence SRB. aim our research was to compare elements SRB cultures isolated from fecal samples patients with healthy...

The community structure of sulfate-reducing bacteria (SRB) of a marine Arctic sediment (Smeerenburgfjorden, Svalbard) was characterized by both fluorescence in situ hybridization (FISH) and rRNA slot blot hybridization by using group- and genus-specific 16S rRNA-targeted oligonucleotide probes. The SRB community was dominated by members of the Desulfosarcina-Desulfococcus group. This group acco...

Microbial populations associated with microbial enhanced oil recovery (MEOR) and their abundance in the Xinjiang Luliang water-flooding petroleum reservoir were investigated using 16S rRNA, nitrate reductases, dissimilatory sulfate reductase, and methyl coenzyme-M reductase-encoded genes to provide ecological information for the potential application of MEOR. 16S rRNA gene miseq sequencing reve...
