Twelve antimony-resistant bacteria were isolated from sediment collected in the vicinity of an antimony oxide-producing factory in Korea. Eight of these strains were heterotrophic Sb(III)-oxidizing bacteria. Phylogenetic study showed that the Sb(III)-oxidizing bacteria fell within two subdivisions of Proteobacteria. Cupriavidus sp. NL4 and Comamonas sp. NL11 belong to the subdivision β-Proteobacteria. Acinetobacter sp. NL1, Acinetobacter sp. NL12, Pseudomonas sp. NL2, Pseudomonas sp. NL5, Pseudomonas sp. NL6, and Pseudomonas sp. NL10 are the members of the γ-subdivision of the Proteobacteria. Among them, Cupriavidus sp. NL4 completely oxidized 100 μmoles of Sb(III) per liter of medium in 500 h, while the other strains were not able to oxidize all of the Sb(III) in the medium, even with longer incubation. The results imply that diverse bacterial lineages are able to detoxify sites polluted with Sb(III) by oxidizing it to Sb(V), and to contribute to antimony cycling in natural environments.
