Iron and sulfur utilisation patterns in chemolithotrophic cultures [PDF]

, 2012
In this study, the growth and behaviour of chemolithotrophic organisms in the presence of both ferrous and tetrathionate ions was investigated. Given the impact of chemolithotrophic metabolic activity upon the chemistry and leaching of mineral sulfide ...

Micrococcus endophyticus strain WH16 oxidizes elemental sulfur in sodic soil: Effect on soil properties and crop performance

Vadose Zone Journal, Volume 25, Issue 5, September/October 2026.
Abstract Micrococcus endophyticus is a heterotrophic, plant growth‐promoting endophyte that thrives within the inner tissues of various plants. This study presents the first report on the elemental sulfur (S°) oxidation potential of the M. endophyticus strain WH16, isolated from high sodic soils.

Bacteria in Nanoparticle Synthesis: Current Status and Future Prospects

International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014
Microbial metal reduction can be a strategy for remediation of metal contaminations and wastes. Bacteria are capable of mobilization and immobilization of metals and in some cases, the bacteria which can reduce metal ions show the ability to precipitate metals at nanometer scale. Biosynthesis of nanoparticles (NPs) using bacteria has emerged as rapidly

Role of pH in the metabolism of Thiobacillus thiooxidans [PDF]

, 1970
The pH for the maximal growth of Thiobacillus thiooxidans was found to be 2.0 to 3.0. The cultures failed to grow when the pH was maintained at 1.0 even up to 390 hours. Such cultures resumed growth after changing the pH to 3.0.

Function and Evolution of the Sox Multienzyme Complex in the Marine Gammaproteobacterium Congregibacter litoralis

International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014
Core sets of sox genes were detected in several genome sequenced members of the environmental important OM60/NOR5 clade of marine gammaproteobacteria. However, emendation of media with thiosulfate did not result in stimulation of growth in two of these strains and cultures of Congregibacter litoralis DSM 17192T did not oxidize thiosulfate to sulfate in

Indirect bioleaching of covellite by Thiobacillus thiooxidans with an oxidant agent [PDF]

, 1995
High copper extraction by the action of Thiobacillus thiooxidans (T.t.) on covellite in presence of iron(III) is explained by indirect mechanism, in which T.t.

Comparison on the removal of hydrogen sulfide in biotrickling filters inoculated with Thiobacillus thioparus and Acidithiobacillus thiooxidans [PDF]

, 2007
Emissions of hydrogen sulfide (H2S) by industrial activities is frequent cause of corrosion and unpleasant odours. Treatment of gaseous emissions contaminated with H2S by biotrickling filters inoculated with single cultures of sulfur oxidizer bacteria ...

Practical Considerations and Challenges Involved in Surfactant Enhanced Bioremediation of Oil

BioMed Research International, Volume 2013, Issue 1, 2013., 2013
Surfactant enhanced bioremediation (SEB) of oil is an approach adopted to overcome the bioavailability constraints encountered in biotransformation of nonaqueous phase liquid (NAPL) pollutants. Fuel oils contain n‐alkanes and other aliphatic hydrocarbons, monoaromatics, and polynuclear aromatic hydrocarbons (PAHs).

Oxygen In The Mix: Is Oxic Microbial Electrosynthesis A Potential Alternative For Biomass Production?

ChemElectroChem, Volume 11, Issue 20, October 16, 2024.
Oxic microbial electrosynthesis (oMES) enables the conversion of renewable electricity and oxic industrial CO2‐streams into biomass by cultivating aerobic, autotrophic hydrogen‐oxidizing bacteria. This article presents the most promising candidates for oMES, discusses their biomass productivity and energy efficiency, and outlines research gaps to bring
