Characterization of tetrathionate hydrolase from the marine acidophilic sulfur-oxidizing bacterium, Acidithiobacillus thiooxidans strain SH

, 2018
Tetrathionate hydrolase (4THase), a key enzyme of the S4-intermediate (S4I) pathway, was partially purified from marine acidophilic bacterium, Acidithiobacillus thiooxidans strain SH, and the gene encoding this enzyme (SH-tth) was identified. SH-Tth is a

Iron and sulfur utilisation patterns in chemolithotrophic cultures

, 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 ...

A new genome of Acidithiobacillus thiooxidans provides insights into adaptation to a bioleaching environment

Research in Microbiology, 2014
Acidithiobacillus thiooxidans is a sulfur oxidizing acidophilic bacterium found in many sulfur-rich environments. It is particularly interesting due to its role in bioleaching of sulphide minerals. In this work, we report the genome sequence of At.

The Ecology of Acidophilic Microorganisms in the Corroding Concrete Sewer Environment

Frontiers in Microbiology, 2017
Concrete corrosion is one of the most significant problems affecting valuable sewer infrastructure on a global scale. This problem occurs in the aerobic zone of the sewer, where a layer of surface corrosion develops on the exposed concrete and the ...

Preparation of pyrite-arsenopyrite concentrate for gold leaching through the use of polyreagent complexes

Горные науки и технологии, 2016
The article focuses on the causes of refractoriness of sulfide ore stock with superdispersed gold inclusions. In order to increase gold recovery, a hypothesis about effective (peroxide) preparation of refractory raw materials in the process of leaching ...
