Short Genome CommunicationsComplete genome sequence of Maribacter sp. T28, a polysaccharide-degrading marine flavobacteria

•We present the whole genome sequence of a marine flavobacteria Maribacter sp. T28.•The genome contains the xylanolytic, alginolytic and pectinolytic enzymes.•Genes encoding alginate lyases and a pectin degradation protein kdgF are located on a polysaccharide utilization locus.•To our knowledge, it is the first report on the ability to degrade xylan, alginate and pectin in Maribacter species.

The degradation of plant polysaccharides by enzymes is an industry of increasing importance. Here we present the complete genome sequence of a marine flavobacteria, Maribacter sp. T28 (=CGMCC 1.15788). The genome comprises 4,271,158 bp in a circular chromosome with a G + C content of 34.4% and contains genes encoding xylanolytic, alginolytic and pectinolytic enzymes. Genes encoding alginate lyases and a pectin degradation protein (kdgF) are located on a polysaccharide utilization locus. Maribacter sp. T28 has the ability to utilize xylan, alginate and pectin for growth. The key degradation products xylose and 2-keto-3- deoxy-gluconate were detected from xylan and pectin, respectively. The Maribacter species genomes provide genetic information regarding polysaccharide-degrading enzymes.
