Molecules, 2015 This paper selects two typical compounds containing organic sulfur as model compounds. Then, by analyzing the chromatograms of gaseous low-temp oxidation products and GC/MS of the extractable matter of the oxidation residue, we summarizing the mechanism ...

Metagenomic and biochemical characterizations of sulfur oxidation metabolism in uncultured large sausage-shaped bacterium in hot spring microbial mats. [PDF]
PLoS ONE, 2012 So-called "sulfur-turf" microbial mats in sulfide containing hot springs (55-70°C, pH 7.3-8.3) in Japan were dominated by a large sausage-shaped bacterium (LSSB) that is closely related to the genus Sulfurihydrogenibium. Several previous reports proposed

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

International Journal of Electrochemical Science, 2015 The electro-oxidation processes of sulfide at Ti/RuO2 anode in alkaline solution are investigated. The experiment results indicated that the electro-oxidation process of sulfide is irreversible, and the control step is mass diffusion.

Molecular Oncology, EarlyView.Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

YeeE-like bacterial SoxT proteins mediate sulfur import for oxidation and signal transduction
Communications BiologyMany sulfur-oxidizing prokaryotes oxidize sulfur compounds through a combination of initial extracytoplasmic and downstream cytoplasmic reactions. Facultative sulfur oxidizers adjust transcription to sulfur availability.

Effects of organic sulfur on oxidation spontaneous combustion characteristics of coking coal
Energy Exploration & Exploitation, 2022 Research on the spontaneous combustion of coal caused by sulfur has always been focused on pyrite in coal but has rarely considered the influence of organic sulfur.

The oxidation of sulfur by microorganisms [PDF]
Experimental Biology and Medicine, 1920 Two groups of phenomena are to be considered in the study of the sulfur cycle: (1) the reduction phenomena and (2) the oxidation phenomena. The first result in the production of hydrogen sulfide and the second in the oxidation of H2S to S and of the latter to H2SO4. Both groups of phenomena result from activities of microorganisms.

FEBS Open Bio, EarlyView.14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.
