Complete genome sequence of a high cesium ion- tolerating bacterium Bacillus sp. Cs-700 isolated from the South China Sea sediment.

Generally, cesium ion (Cs+) which concentration of above the millimolar order is toxic to microorganisms. In this study we report the isolation and genomic characteristics of Bacillus sp. Cs-700, which can grow in media supplemented with 700 mM Cs+ and was one of the most Cs+ tolerating bacteria been reported. Bacillus sp. Cs-700 was isolated from the South China Sea, and comprised one circular chromosome of 4,297,839 bp (40.32 mol% G + C content), containing 4366 predicted protein-coding sequences. We predict that numerous genes related to high cesium tolerating, and the genome of Bacillus sp. Cs-700 will be helpful for further insights into the mechanism of bacterial resistance to excess Cs+ conditions and the bioremediation of radiocesium-polluting environments.
