Microbial Sulfur Cycle in Two Hydrothermal Chimneys on the Southwest Indian Ridge

mBio, 2014
Sulfur is an important element in sustaining microbial communities present in hydrothermal vents. Sulfur oxidation has been extensively studied due to its importance in chemosynthetic pathways in hydrothermal fields; however, less is known about sulfate ...

Microxanox: An R package for simulating an aquatic MICRobial ecosystem that can occupy OXic or ANOXic states

SoftwareX, 2023
Microxanox is an R package to simulate a three functional group ecosystem (cyanobacteria, phototrophic sulfur bacteria, and sulfate-reducing bacteria) with four chemical substrates (phosphorus, oxygen, reduced sulfur, and oxidized sulfur) using a set of ...

Lipids of sulfate-reducing bacteria and sulfur-oxidizing bacteria found in the Dongsheng uranium deposit [PDF]

Chinese Science Bulletin, 2012
U-bearing sandstones from the Dongsheng deposit in Ordos Basin contain abundant C15–C18 fatty acids. The fatty acids may have been derived from modern and ancient organisms including organisms from the intervals of U mineralization. A certain amount of i15:0, a15:0, a17:0 fatty acids coexist with small amounts of i17:1ω7c and 10me16:0, characteristic ...

Exploring Biodiversity and Arsenic Metabolism of Microbiota Inhabiting Arsenic-Rich Groundwaters in Northern Italy

Frontiers in Microbiology, 2019
Arsenic contamination of groundwater aquifers is an issue of global concern. Among the affected sites, in several Italian groundwater aquifers arsenic levels above the WHO limits for drinking water are present, with consequent issues of public concern ...

Synthesis of High-Molecular-Weight Polyhydroxyalkanoates by Marine Photosynthetic Purple Bacteria. [PDF]

PLoS ONE, 2016
Polyhydroxyalkanoate (PHA) is a biopolyester/bioplastic that is produced by a variety of microorganisms to store carbon and increase reducing redox potential.

Physiological and comparative proteomic characterization of Desulfolithobacter dissulfuricans gen. nov., sp. nov., a novel mesophilic, sulfur-disproportionating chemolithoautotroph from a deep-sea hydrothermal vent

Frontiers in Microbiology, 2022
In deep-sea hydrothermal environments, inorganic sulfur compounds are important energy substrates for sulfur-oxidizing, -reducing, and -disproportionating microorganisms.

Microbial pathways in colonic sulfur metabolism and links with health and disease

Frontiers in Physiology, 2012
Sulfur is both crucial to life and a potential threat to health. While colonic sulfur metabolism mediated by eukaryotic cells is relatively well studied, much less is known about sulfur metabolism within gastrointestinal microbes.

Abundance and diversity of denitrifying and anammox bacteria in seasonally hypoxic and sulfidic sediments of the saline Lake Grevelingen

Frontiers in Microbiology, 2016
Denitrifying and anammox bacteria are involved in the nitrogen cycling in marine sediments but the environmental factors that regulate the relative importance of these processes are not well constrained.

Identification of thiosulfate- and sulfur-reducing bacteria unable to reduce sulfate in ricefield soils

European Journal of Soil Biology, 2001
Using peptides as energy sources, H2 as electron donor, thiosulfate as electron acceptors, we isolated, from four ricefield soils originating from France and the Philippines, 52 strains of anaerobes, among which 18 reduced thiosulfate but not sulfate.
