Gene Expression Correlates with Process Rates Quantified for Sulfate- and Fe(III)-Reducing Bacteria in U(VI)-Contaminated Sediments [PDF]

, 2012
Though iron- and sulfate-reducing bacteria are well known for mediating uranium(VI) reduction in contaminated subsurface environments, quantifying the in situ activity of the microbial groups responsible remains a challenge.

Quantification and isotopic analysis of intracellular sulfur metabolites in the dissimilatory sulfate reduction pathway [PDF]

Geochimica et Cosmochimica Acta, 2017
Abstract Microbial sulfate reduction exhibits a normal isotope effect, leaving unreacted sulfate enriched in 34 S and producing sulfide that is depleted in 34 S. However, the magnitude of sulfur isotope fractionation is quite variable. The resulting changes in sulfur isotope abundance have been used to trace microbial sulfate reduction in modern ...

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

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 ...

Thermophilic Sulfate Reduction in Hydrothermal Sediment of Lake Tanganyika, East Africa [PDF]

, 1994
In environments with temperatures above 60 degrees C, thermophilic prokaryotes are the only metabolically active life-forms. By using the (SO42-)-S-35 tracer technique, we studied the activity of sulfate-reducing microorganisms (SRM) in hot sediment from

Faecal Attraction: 40 Years of Research in Gut Microbiology

Nutrition Bulletin, EarlyView.
ABSTRACT This article summarises the 2025 British Nutrition Foundation Annual Lecture given on 25/11/25. It overviews aspects of research in anaerobic microbiology, principally involving the human gut. Until October 2025, Gibson was Professor of Food Microbiology at the University of Reading.

Metabolic Flexibility of Sulfate Reducing Bacteria

Frontiers in Microbiology, 2011
Dissimilatory sulfate-reducing prokaryotes (SRB) are a very diverse group of anaerobic bacteria that are omnipresent in nature and play an imperative role in the global cycling of carbon and sulfur.

NADH and NADPH peroxidases as antioxidant defense mechanisms in intestinal sulfate-reducing bacteria

Scientific Reports, 2023
Animal and human feces typically include intestinal sulfate-reducing bacteria (SRB). Hydrogen sulfide and acetate are the end products of their dissimilatory sulfate reduction and may create a synergistic effect. Here, we report NADH and NADPH peroxidase

Impacts of Climate Change on Groundwater Quality in the Northern Atlantic Coastal Plain: A Review

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 3, June 2026.
ABSTRACT This review integrates hydrogeological and geochemical processes to assess the impacts of climate change on groundwater quality in the Northern Atlantic Coastal Plain (NACP). Projected changes in air temperature, precipitation, and sea‐level rise are expected to influence groundwater recharge, discharge, storage, and seawater intrusion in ...
