Metallic selenides nanomaterials are widely used in many fields, especially for photothermal therapy and thermoelectric devices. However, the traditional chemogenic methods are energy-intensive and environmentally unfriendly. In this study, the first complete genome data of a metallic selenides producing bacterium Bacillus cereus CC-1 was reported. This strain can not only reduce selenite and selenate into elemental selenium nanoparticles (SeNPs), but also synthesize several metallic selenides nanoparticles when adding metal ions (Pb2+, Ag+ and Bi3+) and selenite simultaneously. The size of the genome is 5,308,319 bp with 36.07% G+C content. Several putative genes responsible for heavy metal resistance, salt resistance, and selenate reduction were found. This genome data provide fundamental information, which support the use of this strain for the production of biocompatible photothermal and thermoelectric nanomaterials under mild conditions.
