Draft Genome Sequence of the Agar-Degrading Bacterium Catenovulum sp. Strain DS-2, Isolated from Intestines of Haliotis diversicolor

Catenovulum sp. strain DS-2, isolated from the intestines ofHaliotis diversicolor, is a Gram-positive, aerobic, nonmotile, mesophilic strain and is capable of degrading agar and producing agaro-oligosaccharides.Agar is composedof agarose andagaropectin (1). Agarose consists of linear galactans with a backbone of alternat-ing 3-O-linked-D-galactopyranose and4-O-linked3,6-anhydro--L-galactose units (2). Agarose can be specifically hydrolyzed by aga-rases (3). Catenovulum sp. DS-2 grows well in marine agar 2216E medium, and it can form a clear zone around the colony. Here, we present the genome sequence of Catenovulum sp. DS-2, which was obtained using Solexa paired-end sequencing technology (4) by ShanghaiMajorbioBio-pharmTechnologyCo., Ltd. (Shanghai, China). A library with a fragment length of 300 bp was constructed, and a total of 4,347,955 paired-end reads were generated, resulting ina154-folddepthofcoverage,withanIllumina/ SolexaGenomeAnalyzer IIx (5) (Illumina, SanDiego, CA).
