The characteristics of the bioleaching of realgar by Acidithiobacillus ferrooxidans BY-3 (A. ferrooxidans) were investigated in this work. We examined the effects of using ferrous iron and elemental sulfur as the sole and mixed energy sources on the bioleaching of realgar. Under all experimental conditions, A. ferrooxidans BY-3 significantly enhanced the(More)
The traditional techniques for removing low concentration arsenic are unsuitable. The biosorption characteristics of arsenite (iAs(III)) and monomethyl arsonate (MMA(V)) from aqueous solution by Acidithiobacillus ferrooxidans BY-3 (At. f BY-3) were investigated as a function of pH, contact time, initial arsenic concentration, biomass dosage and temperature(More)
Thermogenesis is a process of heat production in living organisms. It is rare in plants, but it does occur in some species of angiosperm. The heat is generated via plant mitochondrial respiration. As possible involvement in thermogenesis of mitochondrial factors, alternative oxidases (AOXs) and plant uncoupling mitochondrial proteins (PUMPs) have been well(More)
To obtain maximal linear regression correlation coefficient (R 2) of glucose standard curve determinations, single-factor test and response surface methodology were applied to optimize conditions including reaction time, incubation temperature and phenol concentration. For investigating optimization of this method, the effects of different metal ions, amino(More)
