Biosorption and bioaccumulation of chromate from aqueous solution by a newly isolated Bacillus mycoides strain 200AsB1
Microbial chromate (Cr6+) reduction and consequent chromite (Cr3+) biosorption have exhibited potential for the remediation of chromium (Cr)-contaminated water. However, few microorganisms that can accumulate amounts of Cr6+ in their cells have been reported. In this study, a new Cr6+-resistant bacterium was isolated and characterized by physiological, biochemical and molecular tests. Its Cr6+ r...
