Gram-Negative Mesophilic Sulfate-Reducing Bacteria

1992
An overview of the sulfate-reduction process is given in Chapter 24. Most types of dissimilatory sulfate-reducing bacteria that have been isolated from nature and described so far are mesophilic, nonsporeforming anaerobes. They are members of the delta subdivision of the proteobacteria.

Effect of Copresence of Zerovalent Iron and Sulfate Reducing Bacteria on Reductive Dechlorination of Trichloroethylene.

Environmental Science and Technology, 2021
Sulfur amendment of zerovalent iron (ZVI) materials has been shown to improve the reactivity and selectivity of ZVI toward a select group of organohalide contaminants in groundwater, most notably trichloroethene (TCE).

Oxygen defense in sulfate-reducing bacteria

Journal of Biotechnology, 2006
Sulfate-reducing bacteria (SRB) are strict anaerobes that are often found in biotopes where oxic conditions can temporarily exist. The bacteria have developed several defense strategies in order to survive exposure to oxygen. These strategies includes peculiar behaviors in the presence of oxygen, like aggregation or aerotaxis, and enzymatic systems ...

Sulfate-reducing anaerobic bacteria in human feces

The American Journal of Clinical Nutrition, 1977
Human feces contain: 1) Chemotrophic anaerobic bacteria (strains XII, 57, IV) identified with D. desulfuricans ssp. faecalis (nov. ssp.) at a level approaching 10 7/g. 2) Organotrophic anaerobic gram positive rods (strains 30, 35, and 43) at between 10(5) and 10 7/g.

Reduction of molybdate by sulfate-reducing bacteria

BioMetals, 2009
Molybdate is an essential trace element required by biological systems including the anaerobic sulfate-reducing bacteria (SRB); however, detrimental consequences may occur if molybdate is present in high concentrations in the environment. While molybdate is a structural analog of sulfate and inhibits sulfate respiration of SRB, little information is ...

Sulfate Reducing Bacteria

2020
For the first billion years or so on earth, sulfur was more important to life than oxygen. Inorganic sulfate metabolism in anerobic sulfate reducing bacteria involves eight-electron reduction of sulfate to hydrogen sulfide. Sulfate dianion is first activated to the mixed sulfuric–phosphoric anhydride adenyl sulfate (AMP-sulfate) to set up attack by a ...

Sulfate‐reducing bacteria in association with human periodontitis

Journal of Clinical Periodontology, 2000
AbstractBackground, aims: Sulfate‐reducing bacteria (SRB) may be etiologically involved in destructive periodontal diseases. These strictly anaerobic bacteria utilize fermentation products for energy conservation by reduction of sulfate to sulfide. This toxic product can accumulate in periodontal pockets in concentrations causing cellular destruction ...

Control of Sulfate‐Reducing Bacteria

Journal AWWA, 1965
Sulfate‐reducing bacteria have been implicated in numerous instances of damage, as recorded by Postgate. One of the most important of these situations is the corrosion of buried pipelines. Von Wolzogen Kuhr, in 1937, proposed the first widely accepted theory of the corrosion activity of sulfate‐ reducing bacteria. This thesis has been tested by Starkey
