The first complete genome sequence of Microbulbifer celer KCTC12973T, a type strain with multiple polysaccharide degradation genes

Genus Microbulbifer plays important roles in element cycling process in marine environments, and the first type strain KCTC 12973^T (=ISL-39^T = CCUG 54356^T) of M. celer was isolated and identified in 2007. However, the genome sequence of M. celer KCTC 12973^T is still unclear, which complicates the functional exploration and new species identification of other species belonged to this genus. This study reported the complete genome sequence of M. celer KCTC 12973^T with a genome size of 4,346,001 bp. A total of 3601 protein-coding genes were annotated in the genome. The potential genes involved in the polysaccharide degradation, including cellulose, chitin, xylan, and pectate, were found in the protein-coding genes. Besides, the reductase genes of nitrate and nitrite were also annotated in the genome. These findings indicated the potential crucial ecological functions of M. celer KCTC 12973^T for carbon and nitrogen cycles in marine ecosystems.
