MXenes as a Versatile Platform for High‐Energy‐Density Asymmetric Supercapacitors
Carbon Energy, EarlyView.MXenes with high conductivity and tunable surface chemistry are reviewed as advanced electrodes for asymmetric supercapacitors. MAX‐phase synthesis, surface and interlayer engineering, defect modulation, and composite designs are discussed, highlighting enhanced ion transport, pseudocapacitance, energy density, cycling stability, and sustainable routes

Sulfate‐reducing bacteria [PDF]
Critical Reviews in Environmental Science and Technology, 1996 Abstract The corrosion of sewers and the control of odor are the major operational and maintenance problems in wastewater collection systems. The generation of hydrogen sulfide and subsequent sulfuric acid results from microbially mediated reactions, by sulfate‐reducing bacteria (SBR) and sulfide‐oxidizing bacteria.

Oxygen defense in sulfate-reducing bacteria
Journal of Biotechnology, 2006Sulfate-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 bacteria in the periodontal pocket [PDF]
Oral Microbiology and Immunology, 1995 This report is the first to describe the occurrence of sulfate‐reducing bacteria in the human mouth. Samples of subgingival dental plaque were examined for the presence of sulfate‐reducing bacteria. Using enrichment cultures, sulfate‐reducing bacteria were detected in 25 (58%) of 43 individuals, and in 39 (48%) of the 82 samples.

Reduction of molybdate by sulfate-reducing bacteria
BioMetals, 2009Molybdate 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 in association with human periodontitis
Journal of Clinical Periodontology, 2000AbstractBackground, 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 ...

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 ...

Technetium reduction and precipitation by sulfate‐reducing bacteria
Geomicrobiology Journal, 1998Resting cells of the sulfate‐reducing bacterium Desulfovibrio desulfuricans ATCC 29577 were able to precipitate the radionuclide technetium, supplied as the pertechnetate anion (TcO4 ‐), under anaerobic conditions by two discrete mechanisms. Sulfidogenic cultures, supplied with sulfate and lactate as an electron acceptor and donor, respectively ...

Metabolism of Explosive Compounds by Sulfate-Reducing Bacteria
Current Microbiology, 1998The metabolism of various explosive compounds-1,3,5-trinitrobenzene (TNB), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetraazocine (HMX)-by a sulfate-reducing bacterial consortium, Desulfovibrio spp., was studied. The results indicated that the Desulfovibrio spp.
