	Abstract

Sb(III) oxidation was documented in an Agrobacterium tumefaciens isolate that can also oxidize As(III). Equivalent Sb(III) oxidation rates were observed in the parental wild type organism and in two well characterized mutants that cannot oxidize As(III) for fundamentally different reasons. Therefore, despite the literature suggesting Sb(III) and As(III) may be biochemical analogs, Sb(III) oxidation is catalyzed by a pathway different than that used for As(III). Sb(III) and As(III) oxidation was also observed in an eukaryotic acidothermophilic alga belonging to the order Cyanidiales, implying that the ability to oxidize metalloids may be phylogenetically wide spread.
