Electron. j. biotechnol; 53 (), 2021
BACKGROUND Arsenic contamination in the ground water of rural India is a recurrent problem and decon tamination is mostly based on the chemical or physical treatments until now. Microbial bioremediation is eco-friendly, cheap, time-efficient and does not produce any toxic by-products. RESULT In the prese...

Arsenic tolerance and bioleaching from realgar based on response surface methodology by Acidithiobacillus ferrooxidans isolated from Wudalianchi volcanic lake, northeast China

Yan, Lei; Hu, Huixin; Zhang, Shuang; Chen, Peng; Wang, Weidong; Li, Hongyu.
Electron. j. biotechnol; 25 (), 2017
Background: Traditional methods of obtaining arsenic have disadvantages such as high cost and high energy consumption. Realgar is one of the most abundant arsenic sulphide minerals and usually treated as waste in industry. The aim of the present study was to screen an arsenic tolerant bacterium used for ...
