Isolation of a nitrate-reducing bacteria strain from oil field brine and the inhibition of sulfate-reducing bacteria [PDF]

, 2011
A nitrate- reducing bacteria (NRB) strain with vigorous growth, strong nitrate reduction ability, strain B9 2-1, was isolated from Suizhong36-1 oilfield, its routine identification and analysis of 16S rRNA and also the competitive inhibition experiments ...

Multi-omics analyses provide insights into the sulfur metabolism of a novel deep-sea sulfate-reducing bacterium

iScience
Summary: Sulfate-reducing bacteria (SRB) are ubiquitously distributed across various biospheres and play key roles in global sulfur and carbon cycles. However, few deep-sea SRB have been cultivated and studied in situ, limiting our understanding of the ...

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

Integrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Effect of Chloride Ion Concentration on Corrosion of Q235 Steel in Sulfate-Reducing Bacteria Containing Solution

International Journal of Electrochemical Science, 2019
The sedimentary water in crude oil storage tanks contains a large amount of chloride ions and microorganisms, represented by sulfate-reducing bacteria(SRB), which is the main reason for the corrosion of tank bottom.

Review Article: The Impact of the Gut Microbiome on Ulcerative Colitis Pharmacotherapy

Alimentary Pharmacology &Therapeutics, EarlyView.
The gut microbiome modulates ulcerative colitis pharmacotherapy through microbial drug metabolism, immune regulation and altered drug bioavailability. Microbial composition influences response to aminosalicylates, corticosteroids, immunomodulators, biologics and small molecules, while microbiome‐targeted therapies show emerging promise.

Sulfate reducing bacteria applied to domestic wastewater [PDF]

, 2018
The application of sulfate reducing bacteria (SRB) to treat municipal wastewater is seldom considered. For instance, due to low sludge yield it can reduce the amount of excess sludge produced significantly.

Occurrence of sulfate-reducing bacteria in well water: identification of anaerobic sulfidogenic bacterial enrichment cultures

Journal of Water and Health
Bacteriological studies of well water mainly focus on aerobic and facultative aerobic coliform bacteria. However, the presence of obligate anaerobic bacteria in well water, especially sulfate-reducing bacteria (SRB), possible causative agents of some ...

A two-compartment upflow pilot scale bioreactor system for microbial sulfate reduction control studies

MethodsX, 2019
Souring in oil fields occurs mainly due to the activity of sulfate reducing bacteria (SRB). Most of the studies on SRB are performed using upflow packed-bed reactors that have a limitation to describe the region close to the injection wells in oil fields,
