The 16S Rrna Gene

Two strains of Gram-stain-positive, aerobic, spore-forming and rod-shaped bacteria, designated U13T and U14, were isolated from soil of the Ukraine. Comparative analysis of the 16S rRNA gene sequences indicated that these strains belong to the genus Tumebacillus, with the highest 16S rRNA gene sequence similarity with Tumebacillus ginsengisoli Gsoil 1105T (95.48 % and 95.49 %, respectively). Strains U13T and U14 had iso-C15 : 0 and summed features 1 and 4 as the main fatty acids, and were able to grow at pH ranging from pH 5.0 to 9.0 (optimum pH 6.0–7.0), temperatures ranging from 25 to 42 °C (optimum 28–37 °C) and with 0–1 % (w/v) NaCl (optimum 0 %, w/v) on R2A agar medium. Chemotaxonomic data revealed that the cell-wall peptidoglycan type of the two strains was type A1γ (meso-diaminopimelic acid). On the basis of the evidence from this study, strains U13T and U14 represent a novel species of the genus Tumebacillus, for which the name Tumebacillus luteolus sp. nov. is proposed. The type strain is U13T ( = KEMB 7305-100T = JCM 19866T) and a second strain is U14 ( = KEMB 7305-101 = JCM 19867).

The 16S Rrna Gene

Two novel thermophilic bacteria, designated SgZ-9T and SgZ-10T, were isolated from compost. Cells of the two strains were catalase-positive, endospore-forming and Gram-staining-positive rods. Strain SgZ-9T was oxidase-positive and non-motile, and strain SgZ-10T was oxidase-negative and motile. The highest 16S rRNA gene sequence similarity for both strains SgZ-9T and SgZ-10T was observed with Bacillus fortis (97.5 % and 96.9 %, respectively). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SgZ-9T formed a cluster with B. fortis R-6514T and Bacillus fordii R-7190T, and SgZ-10T formed a cluster with Bacillus farraginis R-6540T. The DNA–DNA pairing studies showed that SgZ-9T displayed 41.6 % and 30.7 % relatedness to the type strains of B. fortis and B. fordii , respectively. The 16S rRNA gene sequence similarity between strains SgZ-9T and SgZ-10T was 97.2 %, and the level of DNA–DNA relatedness between them was 39.2 %. The DNA G+C content of SgZ-9T and SgZ-10T was 45.3 and 47.9 mol%, respectively. Chemotaxonomic analysis revealed that both strains contained the menaquinone 7 (MK-7) as the predominant respiratory quinone. The major cellular fatty acids (>5 %) were iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and iso-C17 : 0 in SgZ-9T and iso-C15 : 0, anteiso-C15 : 0, iso-C17 : 0, anteiso-C17 : 0 and iso-C16 : 0 in SgZ-10T. Based on the phenotypic characteristics, chemotaxonomic features, DNA–DNA hybridization with the nearest phylogenetic neighbours and phylogenetic analysis based on the 16S rRNA gene sequences, the two strains were determined to be two distinct novel species in the genus Bacillus , and the names proposed are Bacillus composti sp. nov. SgZ-9T ( = CCTCC AB2012109T = KACC 16872T) and Bacillus thermophilus sp. nov. SgZ-10T (CCTCC AB2012110T = KACC 16873T).

Two Gram-negative, motile, non-spore-forming and slightly halophilic rods (strains SW-145T and SW-156T) were isolated from sea water of the Yellow Sea in Korea. Strains SW-145T and SW-156T grew optimally at 37 and 30–37 °C, respectively, and in the presence of 2–6 % (w/v) NaCl. Strains SW-145T and SW-156T were chemotaxonomically characterized as having ubiquinone-9 as the predominant respiratory lipoquinone and C16 : 0, C18 : 1 ω9c, C16 : 1 ω9c and C12 : 0 3-OH as the major fatty acids. The DNA G+C contents of strains SW-145T and SW-156T were 58 and 57 mol%, respectively. Phylogenetic analyses based on 16S rRNA gene sequences showed that strains SW-145T and SW-156T fell within the evolutionary radiation enclosed by the genus Marinobacter. The 16S rRNA gene sequences of strains SW-145T and SW-156T were 94·8 % similar. Strains SW-145T and SW-156T exhibited 16S rRNA gene sequence similarity levels of 94·3–98·1 and 95·4–97·7 %, respectively, with respect to the type strains of all Marinobacter species. Levels of DNA–DNA relatedness, together with 16S rRNA gene sequence similarity values, indicated that strains SW-145T and SW-156T are members of two species that are distinct from seven Marinobacter species with validly published names. On the basis of phenotypic properties and phylogenetic and genotypic distinctiveness, strains SW-145T (=KCTC 12185T=DSM 16070T) and SW-156T (=KCTC 12184T=DSM 16072T) should be placed in the genus Marinobacter as the type strains of two distinct novel species, for which the names Marinobacter flavimaris sp. nov. and Marinobacter daepoensis sp. nov. are proposed.
