Given the challenges to life at low pH, an analysis of inorganic sulfur compound (ISC) oxidation was initiated in the chemolithoautotrophic extremophile Acidithiobacillus caldus. A. caldus is able to metabolize elemental sulfur and a broad range of ISCs. It has been implicated in the production of environmentally damaging acidic solutions as well as participating in industrial bioleaching opera...

Abstract The biological removal of hydrogen sulfide in biogas is an increasingly adopted alternative to conventional physicochemical processes because its economic and environmental benefits. In this study, a real-scale biotrickling filtration (BTF) process packed with polypropylene carrier was used investigate the high concentrations H2S from anaerobic digester. results show that entirely remo...

Recent advances in technology have increased the necessity of using components with Micro and Nano dimensions. In recent years, the use of bacteria as a renewable tool has hopeful applications in producing different work-pieces. In this study, the effect of Acidithiobacillus Ferrooxidans (A.F) on Vt20 (Titanium alloy) and Cu were investigated. The results illustrated that in the medium of the A...

Arsenopyrite is the most abundant arsenic-bearing sulfide mineral in lithosphere, usually associated with gold ores. The recovery of this highly valuable metal release large quantities soluble arsenic. One way to mitigate effects high concentrations arsenic solution immobilize it as scorodite precipitate, a more stable form. Hence, we addressed formation capacity (under mesophilic conditions) p...
