We report the complete genome sequences of two antimony-oxidizing bacteria, Mesorhizobium sp. strain ANAO-SY3R2, comprising one chromosome (4.3 Mbp) and four circular plasmids, and Hydrogenophaga sp. strain ANAO-22, comprising one chromosome (5.8 Mbp) and two circular plasmids. These genome information extend our understanding of physiological versatility of antimony-transforming microorganisms.
Keywords: Hydrogenophaga; Mesorhizobium; antimony oxidation.
