• A Gram-negative, heterotrophic, marine bacterium, designated strain TT1 , was isolated from seawater collected from the shallow coastal region of Anping Harbour, Tainan, Taiwan. Cells grown in broth cultures were straight rods that were motile by means of a single polar flagellum. The isolate required NaCl for growth and exhibited optimal growth at 30-35 °C, 2-4 % NaCl and pH 7-8. Strain TT1 grew aerobically and was not capable of anaerobic growth by fermentation of glucose or other carbohydrates. Q-10 was the sole major isoprenoid quinone. Cellular fatty acids were dominated by C ω7 (47.5 %), C 2-OH (16.3 %) and C ω8 cyclo (10.6 %). The DNA G+C content was 56.4 mol%. Phylogeny based on 16S rRNA gene sequences showed that strain TT1 formed a distinct genus-level lineage in the family of the class and exhibited the highest sequence similarity with species of the genera (89.9-90.0 % 16S rRNA gene sequence similarity), (89.4-89.9 %) and (89.1-89.7 %). Strain TT1 could be distinguished from species of these phylogenetically closest genera based on differences in DNA G+C contents (56.4 mol% vs 60.0-68.0 mol%), fatty acid profiles and some physiological characteristics. On the basis of the polyphasic taxonomic data from this study, strain TT1 is considered to represent a novel species of a new genus in the family , for which the name gen. nov., sp. nov. is proposed. The type strain of the type species is TT1 ( = JCM 18659  = BCRC 80493 ).
