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

Abstract

Genus Microbulbifer plays important roles in element cycling process in marine environments, and the first type strain KCTC 12973T (=ISL-39T=CCUG 54356T) of M. celer was isolated and identified in 2007. However, the genome sequence of M. celer KCTC 12973T 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 12973T with a genome size of 4,346,001bp. 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 12973T for carbon and nitrogen cycles in marine ecosystems.
