ABSTRACT
A novel Gram-stain-negative, non-motile, strictly aerobic, rod-shaped bacterium was isolated from deep-sea hydrothermal sulfide in the northwest Indian Ocean Ridge and designated as strain IOP_32T. Strain IOP_32T could grow at 4-40 °C (optimum, 37 °C), pH 5-9 (optimum, pH 7-8) and salinity of 0-12 % NaCl (w/v; optimum, 2-3 %). The 16S rRNA gene sequence of strain IOP_32T is most similar to Bizionia fulviae EM7T, Bizionia berychis RA3-3-1T, Bizionia paragorgiae KMM 6029T and Oceanihabitans sediminis S9_10T with 95.5-95.3 % similarity. The phylogenomic analysis indicated that strain IOP_32T forms a distinct lineage with Flaviramulus ichthyoenteri Th78T within the family Flavobacteriaceae. The average nucleotide identity, average amino acid identity and percentage of conserved protein values between strain IOP_32T and the type strains of close genera were 72.3-78.5 %, 67.4-76.9 % and 56.3-61.6 %, respectively. The major cellular fatty acid was anteiso-C15  0. The respiratory quinone was MK-6. The polar lipids were mainly composed of phosphatidylethanolamine, an unidentified aminophospholipid and five unidentified polar lipids. Strain IOP_32T is significantly different from related genera, which is reflected by the wide adaptability to temperature and salinity levels, the composition of phospholipids and fatty acids, and the results of phylogenetic analyses. The phenotypic properties and phylogenetic data suggest that the lineage represents a novel genus and species within the family Flavobacteriaceae, for which the name Wocania indica gen. sp. nov. is proposed, with the type strain IOP_32T (=MCCC 1A14017 T=KCTC 62660 T). We also propose the reclassification of Flaviramulus ichthyoenteri as Wocania ichthyoenteri comb. nov. (Th78T=DSM 26285T=JCM 18634T=KCTC 32142T).
