A Gram-staining-negative, rod-shaped and non-motile bacterial strain, designated 12C25^T, was isolated from the crude-oil-degrading bacterial consortium enriched from mangrove sediment collected in Fujian Province, China. Optimal growth was observed at 25–28 °C, at pH 7.0 and in the presence of 2% (w/v) NaCl + 2% (w/v) KCl. Comparative 16S rRNA gene sequence analysis demonstrated that strain 12C25^Tshared the highest sequence similarity with members of the genusMuricauda(97.7–93.9%), exhibiting 97.7% sequence similarity and 33.7±4% DNA–DNA relatedness toMuricauda aquimarinaSW-63T. The DNA G+C content of strain 12C25^Twas 39.9 mol%. The dominant fatty acids were iso-C_15:1G, iso-C_17:03-OH, iso-C_{15: 0}, C_18:0and iso-C_15:03-OH, and menaquinone with six isoprene units (MK-6) was the only respiratory quinone. On the basis of phenotypic data and phylogenetic inference, the novel strain belongs to the genusMuricauda, but can readily be distinguished from known species of this genushttp://dx.doi.org/10.1601/nm.8170and thus represents a novel species of the genusMuricauda. The nameMuricaudazhangzhouensissp. nov. is proposed and the type strain is 12C25^T(=CGMCC 1.11028^T=MCCC 1F01096^T=DSM 25030^T).
