Two Gram-negative strains of heterotrophic, aerobic, marine bacteria, designated PIM1T and PIN1T, were isolated from seawater samples collected from the shallow coastal region of An-Ping Harbour, Tainan, Taiwan. Cells grown in broth cultures were straight rods and non-motile. The two isolates required NaCl for growth and grew optimally at 30-35 degrees C and 2-5 % NaCl. They grew aerobically and were not capable of anaerobic growth by fermentation of glucose or other carbohydrates. The cellular fatty acids were predominantly iso-branched, with iso-C(15 : 0) (17.0-21.4 %), iso-C(17 : 0) (18.2-21.0 %) and iso-C(17 : 1)omega9c (15.7-16.6 %) as the most abundant components. The predominant isoprenoid quinone was Q-8 (95.2-97.1 %). Strains PIM1T and PIN1T had DNA G+C contents of 46.6 and 46.9 mol%, respectively. Phylogeny based on 16S rRNA gene sequences and DNA-DNA hybridization, together with data from physiological, morphological and chemotaxonomic characterizations, indicated that the two isolates should be classified as representatives of two novel species of the genus Pseudidiomarina of the family Idiomarinaceae, for which the names Pseudidiomarina marina sp. nov. (type strain PIM1T=BCRC 17749T=JCM 15083T) and Pseudidiomarina tainanensis sp. nov. (type strain PIN1T=BCRC 17750T=JCM 15084T) are proposed. In addition, based on the characterization data obtained in this study, it is proposed that Idiomarina homiensis and Idiomarina salinarum should be reclassified as Pseudidiomarina homiensis comb. nov. and Pseudidiomarina salinarum comb. nov., respectively.

Description of Idiomarina insulisalsae sp. nov., isolated from the soil of a sea salt evaporation pond, proposal to transfer the species of the genus Pseudidiomarina to the genus Idiomarina and emended description of the genus Idiomarina.

A halophilic, aerobic Gram-negative bacterium, designated strain CVS-6(T), was isolated from a sea salt evaporation pond on the Island of Sal in the Cape Verde Archipelago. Phylogenetic analysis of the 16S rRNA gene sequence revealed a clear affiliation of the organism with members of the family Idiomarinaceae. Sequence similarities between CVS-6(T) and the type strains of the species of the genera Pseudidiomarina and Idiomarina ranged from 93.7% to 96.9%. The major isoprenoid quinone was ubiquinone 8 (Q-8). The major cellular fatty acids were 15:0 iso (21.8%), 17:0 iso (12.5%), 17:1 iso omega9c (10.7%), and 16:1 omega7c (10.6%). The DNA G+C content was 51.6 mol%. The species represented by strain CVS-6(T) could be distinguished from the species of the genera Pseudidiomarina and Idiomarina; however, it was not possible to distinguish both genera from each other using the phenotypic or chemotaxonomic characteristics examined. Consequently, we propose that the species classified in the genus Pseudidiomarina should be transferred to the genus Idiomarina. We also propose that, on the basis of physiological and biochemical characteristics, strain CVS-6(T) (=LMG 23123=CIP 108836) represents a new species which we name Idiomarina insulisalsae.
