Two bacterial strains (JC167T and JC168) were isolated from a soil sample collected from Mandpam, Tamilnadu, India. Colonies of both strains were orange and cells Gram-stain-positive. Cells were small rods, and formed terminal endospores of ellipsoidal to oval shape. Both strains were positive for catalase, oxidase and hydrolysis of starch/gelatin, and negative for chitin hydrolysis, H2S production, indole production and nitrate reduction activity. Major fatty acids of both strains (>5 %) were anteiso-C15 : 0, iso-C16 : 0, iso-C15 : 0, anteiso-C17 : 0, iso-C14 : 0 and C16 : 0 with minor (<5 but >1 %) amounts of iso-C17 : 0, anteiso-C17 : 0 B/iso-C17 : 0 I and C16 : 1ω11c. Diphosphatydilglycerol, phosphatidylethanolamine and phosphatidylglycerol were the major polar lipids of both strains. Cell wall amino acids were l-alanine, d-alanine, d-glutamic acid and meso-diaminopimelic acid. β-Carotene and five unidentified carotenoids were present in both strains. Mean genomic DNA G+C content was 53.4±1 mol% and the two strains were closely related (mean DNA–DNA hybridization >90 %). 16S rRNA gene sequence comparisons of both strains indicated that they represent species of the genus Bacillus within the family Bacillaceae of the phylum Firmicutes . Both strains had a sequence similarity of 97.6 % with Bacillus saliphilus 6AGT and <96.8 % with other members of the genus Bacillus . Sequence similarity between strain JC167T and 168 was 100 %. Strain JC167T showed 25.8±1 % reassociation (based on DNA–DNA hybridization) with B. saliphilus DSM 15402T ( = 6AGT). Distinct morphological, physiological and genotypic differences from previously described taxa support the classification of strain JC167T as a representative of a novel species of the genus Bacillus , for which the name Bacillus luteus sp. nov. is proposed. The type strain is JC167T ( = KCTC 33100T = LMG 27257T).

Isopora Palifera

A bacterial strain designated SW15T was isolated from a sample of the reef-building coral Isopora palifera, collected in southern Taiwan. The novel strain was characterized using a polyphasic taxonomic approach. Cells of strain SW15T were Gram-negative, aerobic, light yellow, rod-shaped and motile by means of a single polar flagellum. In phylogenetic analyses based on 16S rRNA gene sequences, strain SW15T appeared to belong to the genus Idiomarina in the class Gammaproteobacteria and to be most closely related to Idiomarina homiensis PO-M2T (97.6 % sequence similarity). Strain SW15T exhibited optimal growth between 20 and 30 °C, with NaCl between 3 % and 4 % (w/v) and at a pH value between 7 and 8. Predominant cellular fatty acids were iso-C15 : 0 (31.1 %), iso-C17 : 0 (15.4 %), iso-C17 : 1ω9c (10.0 %) and C16 : 0 (8.8 %). The major respiratory quinone was ubiquinone Q-8. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylserine, an uncharacterized aminolipid and several uncharacterized phospholipids. The DNA G+C content was 51.1 mol%. The level of DNA–DNA relatedness between strain SW15T and Idiomarina homiensis PO-M2T was 42.6–56.5 %. The results of physiological and biochemical tests allowed the clear phenotypic differentiation of the novel strain from established species of the genus Idiomarina . Based on the genotypic, phenotypic and chemotaxonomic data, strain SW15T represents a novel species in the genus Idiomarina , for which the name Idiomarina aquimaris sp. nov. is proposed, with SW15T ( = LMG 25374T = BCRC 80083T) as the type strain.
