Abstract:
A taxonomic study was carried out on strain 3PC125-7T, 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 °C, at pH 7 and in 1-3 % (w/v) NaCl. On the basis of the results of 16S rRNA gene sequence analysis, strain 3PC125-7T represents a member of the genus Muricauda, with the highest sequence similarity to Muricauda olearia CL-SS4T (96.7 %), followed by Muricauda marina H19-56T (96.7 %) and nine other species of the genus Muricauda(93.5-95.8 %). The principal fatty acids of 3PC125-7T were iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1G 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 3PC125-7T was 41.8 mol%. Based on the phylogenetic, phenotypic and chemotaxonomic data obtained in this study, strain 3PC125-7T is considered to represent a novel species in the genus Muricauda, for which the name Muricaudaindica sp. nov. is proposed, with the type strain 3PC125-7T (=MCCC 1A03198T=KCTC 52318T).
