Biomethylation of arsenic is usually considered as a detoxification of arsenic because toxicity of most organic methylated arsenic is much less than that of inorganic arsenic. We investigated the feasibility of a novel bioremediation using an arsenic methylating bacterium. An arsenic methylating bacterium Bacillus cereus strain R2, isolated from soil in Miyazaki, was evaluated for growth characteristics and arsenic metabolism. The growth of strain R2 was inhibited in 50.0 mg As/l arsenic medium. Strain R2 metabolized arsenite (
