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 4,271,158bp 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.
