Elemental Sulfur Oxidation by Thiobacillus spp. and Aerobic Heterotrophic Sulfur-Oxidizing Bacteria
Pedosphere, 2010Elemental sulphur (S0), a natural source of sulphur fertilizer, should be biologically oxidized before it becomes available to plants. An incubation experiment to determine the oxidation rate and to evaluate the roles of thiobacilli and heterotrophic sulphur-oxidizing bacteria in S0 oxidation was conducted.

Inorganic sulfur oxidizing system in green sulfur bacteria
Photosynthesis Research, 2010Green sulfur bacteria use various reduced sulfur compounds such as sulfide, elemental sulfur, and thiosulfate as electron donors for photoautotrophic growth. This article briefly summarizes what is known about the inorganic sulfur oxidizing systems of these bacteria with emphasis on the biochemical aspects.

Multifarious characteristics of sulfur-oxidizing bacteria residing in rice rhizosphere
Folia Microbiologica, 2023Sulfur-oxidizing bacteria (SOB) are versatile microorganisms known for their ability to oxidize various reduced sulfur compounds, namely, elemental sulfur (S0), hydrogen sulfide (H2S), tetrathionate (S4O62-), and trithionate (S3O62-) to sulfate (SO42-).

The potential for diazotrophy in iron- and sulfur-oxidizing acidophilic bacteria
Archives of Microbiology, 1995Acetylene reduction was observed with ferrousiron-oxidizingThiobacillus ferrooxidans, as expected from previous studies with this bacterium. Acetylene reduction was also found during the growth ofT. ferrooxidans on tetrathionate. OnlyLeptospirillum ferrooxidans, one of several other phylogenetically diverse, ferrous-iron-and/or sulfur-oxidizing ...

Evaluation of Joint Toxicity of Btex Mixtures Using Sulfur-Oxidizing Bacteria
SSRN Electronic Journal, 2022Benzene (B), toluene (T), ethylbenzene (E), and xylenes (X) are petrochemicals vital in various industrial and commercial processing but identified as priority pollutants due to their high toxicity. The objective of this study was to investigate the toxicological nature of BTEX mixtures under controlled laboratory aquatic conditions using sulfur ...

Role of Sulfur Oxidizing Bacteria in the Degradation of Concrete
CORROSION 1984, 1984Abstract Concrete exposed to sewage or industrial waste in the presence of air and inorganic reduced sulfur compounds often degrades rapidly. These conditions stimulate the growth of the sulfur-oxidizing bacteria Thiobacillus which generate sulfuric acid as the end-product of their metabolism.

Physiology and Genetics of Sulfur-oxidizing Bacteria
1997Reduced inorganic sulfur compounds are oxidized by members of the domains Archaea and Bacteria. These compounds are used as electron donors for anaerobic phototrophic and aerobic chemotrophic growth, and are mostly oxidized to sulfate. Different enzymes mediate the conversion of various reduced sulfur compounds.

Quantifying Sulfur Oxidizing Bacteria Using qPCR
CORROSION 2018, 2018Abstract The understanding of microbiologically influenced corrosion (MIC), specifically the role different species of microorganisms play in the process, is continuously evolving. Recently, bacteria beyond typically implicated sulfate reducing bacteria (SRB) and acid producing bacteria (APB) have been found to influence corrosion ...
