Antimony (Sb) is a naturally occurring toxic metalloid. Although the concentrations of Sb in soils are generally low, elevated levels of Sb have been introduced through mining and other anthropogenic activities (1). Despite its toxicity, microorganisms have evolved mechanisms for resistance and redox transformations of Sb (2–5).
