Strain B538T is a Gram-positive, motile, rod-shaped bacterium, which was isolated from Xinjiang province in China. This organism grew optimally at 30–35 °C and pH 8.0–8.5. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain B538T belonged to the genus Paenibacillus and chemotaxonomic data (DNA G+C content, 47.0 mol%; major isoprenoid quinone, MK-7; cell wall type, A1γ meso-diaminopimelic acid; major fatty acids, anteiso-C15 : 0 and C16 : 0) supported affiliation of the isolate with the genus Paenibacillus. Comparative 16S rRNA gene sequence analyses showed that the isolate was most closely related to Paenibacillus glycanilyticus DS-1T, with 16S rRNA gene sequence similarity of 98.1 %; sequence similarities to other members of the genus Paenibacillus used in the phylogenetic tree were less than 96.5 %. The DNA–DNA relatedness between strain B538T and P. glycanilyticus DS-1T was about 8.0 %. On the basis of physiological and molecular properties, strain B538T (=KCTC 3952T=DSM 16970T) is proposed as the type strain of a novel species within the genus Paenibacillus, for which the name Paenibacillus xinjiangensis sp. nov. is proposed.

A Gram-positive, aerobic, actinobacterial strain with rod-shaped spores, designated YIM 63158T, was isolated from the surface-sterilized roots of Artemisia annua L. collected from Yunnan province, south-west China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 63158T belonged to the genus Pseudonocardia. The closest neighbours were ‘Pseudonocardia sichuanensis’ KLBMP 1115 (99.9 % 16S rRNA gene sequence similarity), Pseudonocardia adelaidensis EUM 221T (99.1 %) and Pseudonocardia zijingensis DSM 44774T (98.8 %); sequence similarities to other members of the genus Pseudonocardia ranged from 98.6 to 94.4 %. The chemotaxonomic characteristics, such as the cell-wall diaminopimelic acid, whole-cell sugars, fatty acid components and major menaquinones, suggested that the isolate belonged to the genus Pseudonocardia. The G+C content of the genomic DNA was 73.3 mol%. On the basis of physiological, biochemical and chemotaxonomic data, including low DNA–DNA relatedness between the isolate and other members of the genus Pseudonocardia, it is proposed that strain YIM 63158T represents a novel species in this genus, with the name Pseudonocardia kunmingensis sp. nov. The type strain is YIM 63158T ( = DSM 45301T  = CCTCC AA 208081T).

Emended Description

A polyphasic taxonomic study was performed on 22 thermotolerant, aerobic, endospore-forming bacteria from dairy environments. Seventeen isolates were retrieved from raw milk, one from a filter cloth and four from grass, straw or milking equipment. These latter four isolates (R-6546, R-7499, R-7764 and R-7440) were identified as Bacillus thermoamylovorans based on DNA–DNA hybridizations (values above 70 % with Bacillus thermoamylovorans LMG 18084T) but showed discrepancies in characteristics with the original species description, so an emended description of this species is given. According to 16S rRNA gene sequence analysis and DNA–DNA hybridization experiments, the remaining 18 isolates (R-6488T, R-28193, R-6491, R-6492, R-7336, R-33367, R-6486, R-6770, R-31288, R-28160, R-26358, R-7632, R-26955, R-26950, R-33520, R-6484, R-26954 and R-7165) represented one single species, most closely related to Bacillus thermoamylovorans (93.9 % 16S rRNA gene sequence similarity), for which the name Bacillus thermolactis is proposed. Cells were Gram-stain-positive, facultatively anaerobic, endospore-forming rods that grew optimally at 40–50 °C. The cell wall peptidoglycan type of strain R-6488T, the proposed type strain, was A1γ based on meso-diaminopimelic acid. Major fatty acids of the strains were C16 : 0 (28.0 %), iso-C16 : 0 (12.1 %) and iso-C15 : 0 (12.0 %). MK-7 was the predominant menaquinone, and major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and some unidentified phospholipids. DNA G+C content was 35.0 mol%. Phenotypic properties allowed discrimination from other thermotolerant species of the genus Bacillus and supported the description of the novel species Bacillus thermolactis, with strain R-6488T ( = LMG 25569T  = DSM 23332T) as the proposed type strain.

Two Gram-stain-positive, rod-shaped and endospore-forming bacteria, designated WM-1T and WM-4, were isolated from a paddy soil and a forest soil, respectively, in South China. Comparative 16S rRNA gene sequence analyses showed that both strains were members of the genus Oceanobacillus and most closely related to Oceanobacillus chironomi LMG 23627T with pairwise sequence similarity of 96.0 %. The isolates contained menaquinone-7 (MK-7) as the respiratory quinone and anteiso-C15 : 0, anteiso-C17 : 0 and iso-C15 : 0 as the major fatty acids (>10 %). Polar lipids consisted of a predominance of diphosphatidylglycerol and moderate to minor amounts of phosphatidylglycerol and phosphatidylinositol. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The DNA G+C content was 38.6–39.2 mol%. The 16S rRNA gene sequence of strain WM-1T displayed 99.7 % similarity to that of strain WM-4, and DNA–DNA hybridization between the two strains showed a relatedness value of 91 %. Based on the results of this polyphasic study, strains WM-1T and WM-4 represent a novel species in the genus Oceanobacillus , for which the name Oceanobacillus luteolus sp. nov. is proposed. The type strain is WM-1T ( = KCTC 33119T = CGMCC 1.12406T).

A Gram-stain-positive, non-spore-forming bacterium (GW5-5797T) was isolated on soil extract agar from sand collected at a depth of 5 m in the Caribbean Sea near Grenada. 16S rRNA gene sequence analysis and similarity studies showed that strain GW5-5797T belongs to the genus Nocardia, and is most closely related to Nocardia speluncae N2-11T (99.2 % similarity) and Nocardia jinanensis 04-5195T (99.2 %) and more distantly related to Nocardia rhamnosiphila 202GMOT (98.6 %) and other Nocardia species. Strain GW5-5797T could be distinguished from all other recognized Nocardia species by sequence similarity values less than 98.5 %. The peptidoglycan diamino acid was meso-diaminopimelic acid. Strain GW5-5797T exhibited a quinone system with the predominant compounds MK-8(H4ω-cyclo) and MK-8(H2). The polar lipid profile of GW5-5797T consisted of the major compounds diphosphatidylglycerol, phosphatidylethanolamine and an unidentified glycolipid, moderate amounts of phosphatidylinositol and a phosphatidylinositol mannoside and minor amounts of several lipids including a second phosphatidylinositol mannoside. The polyamine pattern contained the major compound spermine and moderate amounts of spermidine. The major fatty acids were C16 : 0, C18 : 1ω9c and 10-methyl C18 : 0. These chemotaxonomic traits are in excellent agreement with those of other Nocardia species. The results of DNA–DNA hybridizations and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain GW5-5797T from the most closely related species, showing 16S rRNA gene sequence similarities >98.5 %. Strain GW5-5797T therefore merits separate species status, and we propose the name Nocardia grenadensis sp. nov., with the type strain GW5-5797T ( = CCUG 60970T  = CIP 110294T).

A Gram-staining-positive bacterium, designated AS-0823T, which formed spiral spore chains on the aerial mycelium, was isolated from the intestinal tract of Armadillidium vulgare, a small terrestrial crustacean commonly found on the ground around houses in Japan. 16S rRNA gene sequence analysis showed that the isolate belonged to the genus Streptomyces and was most closely related to Streptomyces longisporus ISP 5166T (98.6 % 16S rRNA gene sequence similarity), Streptomyces curacoi NBRC 12761T (98.4 %) and Streptomyces griseoruber NBRC 12873T (98.4 %). The affiliation of strain AS-0823T to the genus Streptomyces was supported by chemotaxonomic data: iso-C16 : 0, anteiso-C15 : 0, C16 : 0, iso-C15 : 0 and anteiso-C17 : 0 as the major cellular fatty acids, ll-diaminopimelic acid as the characteristic diamino acid in the peptidoglycan and the absence of mycolic acids. DNA–DNA hybridization and physiological and biochemical analysis supported the differentiation of strain AS-0823T from S. longisporus JCM 4395T. Therefore, strain AS-0823T represents a novel species, for which the name Streptomyces coacervatus sp. nov. is proposed. The type strain is AS-0823T ( = IFM 11055T  = DSM 41983T  = JCM 17138T).

The taxonomic position of a rhizosphere soil isolate, designated strain SR8.15T, was determined by using a polyphasic approach. Phylogenetic analysis based on an almost-complete 16S rRNA gene sequence of the strain showed that it formed a well-separated sub-branch within the radiation encompassing the genus Saccharopolyspora. Highest levels of 16S rRNA gene sequence similarity were found between strain SR8.15T and Saccharopolyspora shandongensis CGMCC 4.3530T (98.9 %) and Saccharopolyspora spinosa DSM 44228T (98.5 %). However, these strains shared low levels of DNA–DNA relatedness (<26 %). Strain SR8.15T had chemical characteristics consistent with its classification in the genus Saccharopolyspora. It contained meso-diaminopimelic acid as the diagnostic diamino acid. Whole-cell hydrolysates contained arabinose and galactose. The diagnostic phospholipids were phosphatidylcholine, phosphatidylglycerol and phosphatidylinositol. The main menaquinone was MK-9(H4). No mycolic acid was detected. The predominant cellular fatty acid was iso-C16 : 0. The G+C content of the genomic DNA of strain SR8.15T was 70.3 mol%. Strain SR8.15T had a phenotypic profile that readily distinguished it from recognized representatives of the genus Saccharopolyspora. It is evident from its combined genotypic and phenotypic properties that strain SR8.15T represents a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora phatthalungensis sp. nov. is proposed. The type strain is SR8.15T (=TISTR 1921T=BCC 35844T=NRRL B-24798T).
