Pectic oligosaccharides, which are considered to be potential prebiotics, may be generated by pectin-degrading enzymes. Here, we report the complete genome sequence of the pectin-degrading marine bacterium, Flavobacteriaceae bacterium GSB9, which was isolated from seawater of South Korea. The complete genome sequence revealed that the chromosome was 3,630,376 bp in size, had a G + C content of 36.6 mol%, and was predicted to encode 3100 protein-coding sequences (CDSs), 40 tRNAs, and six 16S–23S-5S rRNAs. Genome sequence analysis revealed that this strain possesses multiple genes predicted to encode pectin-degrading enzymes. Our analysis may facilitate the future application of this strain against pectin in various industries.

果胶寡糖被认为是潜在的益生元，可能是由果胶降解酶产生的。在这里，我们报告了从韩国海水中分离出来的果胶降解海洋细菌黄杆菌科细菌 GSB9 的完整基因组序列。完整的基因组序列显示，染色体大小为3,630,376 bp，G + C含量为36.6 mol%，预计编码3100个蛋白质编码序列（CDS）、40个tRNA和6个16S–23S-5S rRNA 。基因组序列分析表明，该菌株拥有多个预计编码果胶降解酶的基因。我们的分析可能有助于该菌株未来在各个行业中针对果胶的应用。
