abstract= 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).,
