Draft genome sequence of Ochrobactrum pseudogrignonense strain CDB2, a highly efficient arsenate-resistant soil bacterium from arsenic-contaminated cattle dip sites

We report the 4.97-Mb draft genome sequence of a highly efficient arsenate-resistant bacterium, Ochrobactrum sp. strain CDB2. It contains a novel arsenic resistance (ars) operon (arsR-arsC1-ACR3-arsC2-arsH-mfs) and two non-operon-associated ars genes, arsC3 and arsB. The genome information will aid in the understanding of the arsenic resistance mechanism of this and other bacterial species.
