摘要

Alishewanella sp. WH16-1 (= CCTCC M201507) is a facultative anaerobic, motile, Gram-negative, rod-shaped bacterium isolated from soil of a copper and iron mine. This strain efficiently reduces chromate (Crsup6+/sup) to the much less toxic Crsup3+/sup. In addition, it reduces sulfate (SOsub4/sub sup2?/sup) to Ssup2?/sup. The Ssup2?/sup could react with Cdsup2+/sup to generate precipitated CdS. Thus, strain WH16-1 shows a great potential to bioremediate Cr and Cd contaimination. Here we describe the features of this organism, together with the draft genome and comparative genomic results among strain WH16-1 and other Alishewanella strains. The genome comprises 3,488,867?bp, 50.4?%?G?+?C content, 3,132 protein-coding genes and 80 RNA genes. Both putative chromate- and sulfate-reducing genes are identified.
