A taxonomic study was carried out on strain 3PC125-7(T), which was isolated from the deep sea water of the Indian Ocean. The bacterium was rod-shaped, non-flagellated, Gram-stain-negative, oxidase- and catalase-positive and strictly aerobic. Optimal growth was observed at 25-37 degrees C, at pH 7 and in 1-3 % (w/v) NaCl. On the basis of the results of 16S rRNA gene sequence analysis, strain 3PC125-7(T) represents a member of the genus Muricauda, with the highest sequence similarity to Muricauda olearia CL-SS4(T) (96.7 %), followed by Muricauda marina H19-56(T) (96.7%) and nine other species of the genus Muricauda (93.5-95.8 %). The principal fatty acids of 3PC125-7(T) were iso-C-15:0, iSO C-17(:0) 3-OH and iso-C(15:1)G and the sole respiratory quinone was menaquinone-6. The polar lipids comprise phosphatidylethanolamine, six unidentified phospholipids and three unknown lipids. The genomic DNA G+C content of 3PC125-7(T) was 41.8 mol%. Based on the phylogenetic, phenotypic and chemotaxonomic data obtained in this study, strain 3PC125-7(T) is considered to represent a novel species in the genus Muricauda, for which the name Muricauda indica sp. nov. is proposed, with the type strain 3PC125-7(T) (=MCCC 1A03198(T)=KCTC 52318(T)).
