Pseudidiomarina taiwanensis gen. nov., sp. nov., a marine bacterium isolated from shallow coastal water of An-Ping Harbour, Taiwan, and emended description of the family Idiomarinaceae.
Two strains of heterotrophic, aerobic, marine bacteria, designated strains PIT1T 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 degrees 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(15 : 0) iso and C(17 : 0) iso representing the most abundant components. The DNA G+C contents of strains PIT1(T) 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 Idiomarinaceae, for which the name Pseudidiomarina gen. nov. is proposed. Pseudidiomarina taiwanensis sp. nov. is the type species of the novel genus (type strain PIT1T = BCRC 17465T = JCM 13360T).
