Genome sequence of an ulvan-degrading bacterium, Vibrio sp. strain 10N, is presented. The genome is 5,358,550 bp with a G + C content of 46.5%. A total of 4,712 coding sequences, including two novel ulvan lyase genes encoding a BNR4 and a glycoside hydrolase (GH88) motif, are known to be involved in the degradation of green algae.
Keywords: Vibrio; green alga; seawater; ulvan.
