Abstract

Two strains of heterotrophic, aerobic, marine bacteria, designated strains PIT1 and PIT2, were isolated from sea-water samples collected at the shallow coastal region of An-Ping Harbour, Tainan, Taiwan. Both strains were Gram-negative. Cells grown in broth cultures were straight rods that were non-motile, lacking flagella. Both strains required NaCl for growth and exhibited optimal growth at 30–35 °C, 1–4 % NaCl and pH 8. They grew aerobically and were incapable of anaerobic growth by fermentation of glucose or other carbohydrates. Cellular fatty acids were predominantly iso-branched, with C iso and C iso representing the most abundant components. The DNA G+C contents of strains PIT1 and PIT2 were 49·3 and 48·6 mol%, respectively. Phylogeny based on 16S rRNA gene sequences, together with data from phenotypic and chemotaxonomic characterization, revealed that the two isolates could be assigned to a novel genus in the family , for which the name gen. nov. is proposed. sp. nov. is the type species of the novel genus (type strain PIT1=BCRC 17465=JCM 13360).
