Comamonas terrae, a Gram-negative, rod-shaped bacterium isolated from agricultural soil in Thailand, is able to oxidize arsenite to arsenate in soil and water systems. X-ray absorption near-edge structure (XANES) spectroscopy was used to analyze arsenic speciation in culture supernatants from Comamonas terrae grown in arsenite-containing media to demonstrate its arsenite oxidation capability. This strain offers new opportunities in soil bioremediation processes based on its capability to transform As(III) into the less-toxic As(V).
