Microbial Antimony Biogeochemistry: Enzymes, Regulation, and
Abstract. Antimony (Sb) is a toxic metalloid that occurs widely at trace concentrations in soil, aquatic systems, and the atmosphere. Nowadays, with the development of its new industrial applications and the corresponding expansion of antimony mining activities, the phenomenon of antimony pollution has become an Abstract. Antimony (Sb) is a widespread metalloid and Sb contamination has drawn increasing attention. Microorganisms are one of the main drivers of Sb transformation, which is closely associated with its mobility, toxicity and bioavailability. This chapter examines Sb biotransformation processes (i.e., oxidation, reduction and Microbial Transformations of Antimony SpringerLink
