Two closely related, Gram-stain-negative, rod-shaped, spore-forming strains, B27T and F6-B70, were isolated from soil samples of Tianmu Mountain National Natural Reserve in Zhejiang, China. Phylogenetic analysis based on 16S rRNA gene and rpoB sequences indicated that the isolates were members of the genus Paenibacillus. Both isolates were closely related to Paenibacillus ehimensis IFO 15659T, Paenibacillus elgii SD17T and Paenibacillus koreensis YC300T (≥95.2 % 16S rRNA gene sequence similarity). DNA–DNA relatedness between strain B27T and P. ehimensis DSM 11029T, P. elgii NBRC 100335T and P. koreensis KCTC 2393T was 21.2, 28.6 and 16.8 %, respectively. The major cellular fatty acids of strains B27T and F6-B70 were anteiso-C15 : 0 and iso-C15 : 0. The cell wall contained meso-diaminopimelic acid. The two isolates differed from their closest neighbours in terms of phenotypic characteristics and cellular fatty acid profiles (such as variable for oxidase, negative for methyl red test, unable to produce acid from d-fructose and glycogen and relatively higher amounts of iso-C15 : 0 and lower amounts of C16 : 0 and iso-C16 : 0). Strains B27T and F6-B70 represent a novel species of the genus Paenibacillus, for which the name Paenibacillus tianmuensis sp. nov. is proposed. The type strain is B27T ( = DSM 22342T  = CGMCC 1.8946T).

A xylanolytic bacterium, strain S1-3T, was isolated from soil collected in Nan province, Thailand. It was characterized taxonomically based on phenotypic characteristics and 16S rRNA gene sequence comparison. The strain was a Gram-stain-positive, facultatively anaerobic, spore-forming, rod-shaped bacterium. It contained meso-diaminopimelic acid in the cell-wall peptidoglycan. The major menaquinone was MK-7. Iso-C16 : 0 (39.5 %) and anteiso-C15 : 0 (26.8 %) were predominant cellular fatty acids. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and lysyl-phosphatidylglycerol were the major polar lipids. The DNA G+C content was 53.3 mol%. Phylogenetic analysis using 16S rRNA gene sequences showed that strain S1-3T was affiliated to the genus Cohnella, and was closely related to Cohnella ginsengisoli GR21-5T and Cohnella thermotolerans CCUG 47242T with 95.7 and 95.3 % sequence similarity, respectively. Strain S1-3T could be clearly distinguished from related species of the genus Cohnella by its physiological and biochemical characteristics as well as by its phylogenetic position. Therefore, the strain represents a novel species of the genus Cohnella, for which the name Cohnella thailandensis sp. nov. is proposed. The type strain is S1-3T (=KCTC 22296T =TISTR 1890T =PCU 306T).

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.

A Genome

A novel actinomycete, strain SMC 257T, was isolated from a soil sample collected from mountain forest, Nan Province, Thailand. Strain SMC 257T formed tightly closed spiral spore chains on aerial mycelia. A polyphasic approach was used for the taxonomic study of this strain. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SMC 257T belonged to the genus Nonomuraea , and the closest phylogenetically related species were Nonomuraea roseoviolacea subsp. carminata JCM 9946T (98.9 % 16S rRNA gene sequence similarity), Nonomuraea rhodomycinica TBRC 6557T (98.4 %), and Nonomuraea roseoviolacea subsp. roseoviolacea JCM 3145T (98.3 %). Genome sequencing revealed a genome size of 9.76 Mbp and a G+C content of 72.3 mol%. The genome average nucleotide identity (ANI) and the digital DNA–DNA hybridization (dDDH) values that distinguished this novel strain from its closest related species were species boundary of 95–96 % and 70 %, respectively. The cell wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars were glucose, ribose, madurose and mannose. The major menaquinone was MK-9(H4). The polar lipid profile consisted of phosphatidylethanolamine, hydroxyphosphatidylethanolamine, lysophosphatidylethanolamine, diphosphatidylglycerol, N-phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The predominant cellular fatty acids were C17 : 0 10-methyl and iso-C16 : 0. Based on comparative analysis of phenotypic, chemotaxonomic and genotypic data, strain SMC 257T is considered to represent a novel species of the genus Nonomuraea , for which the name Nonomuraea montanisoli is proposed. The type strain is SMC 257T (=TBRC 13065T=NBRC 114772T).
