An ivory/yellow, Gram-stain-negative, short-rod-shaped, aerobic bacterial strain, designated JC2948T, was isolated from a soil sample taken from Gwanak Mountain, Republic of Korea. 16S rRNA gene sequence analysis indicated that strain JC2948T belongs to the genus Burkholderia . The test strain showed highest sequence similarities to Burkholderia tropica LMG 22274T (97.6 %), Burkholderia acidipaludis NBRC 101816T (97.5 %), Burkholderia tuberum LMG 21444T (97.5 %), Burkholderia sprentiae LMG 27175T (97.4 %), Burkholderia terricola LMG 20594T (97.3 %) and Burkholderia diazotrophica LMG 26031T (97.1 %). Based on average nucleotide identity (ANI) values, the new isolate represents a novel genomic species as it shows less than 90 % ANI values with other closely related species. Also, other phylosiological and biochemical comparisons allowed the phenotypic differentiation of strain JC2948T from other members of the genus Burkholderia . Therefore, we suggest that this strain should be classified as the type strain of a novel species of the genus Burkholderia . The name Burkholderia monticola sp. nov. (type strain, JC2948T = JCM 19904T = KACC 17924T) is proposed.

A novel actinomycete, designated strain NEAU-Z6T, was isolated from eggplant (Solanum melongena L.) root. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain NEAU-Z6T belonged to the genus Nonomuraea , with highest sequence similarity to Nonomuraea monospora PT 708T (98.83 %), Nonomuraea rosea GW 12687T (98.55 %) and Nonomuraea rhizophila YIM 67092T (98.02 %). Sequence similarities between strain NEAU-Z6T and other species of the genus Nonomuraea ranged from 97.94 % ( Nonomuraea candida HMC10T) to 96.30 % ( Nonomuraea wenchangensis 210417T). Key morphological, physiological and chemotaxonomic characteristics of strain NEAU-Z6T were congruent with the description of the genus Nonomuraea . The G+C content of the genomic DNA was 64.51 mol%. DNA–DNA relatedness and comparative analysis of physiological, biochemical and chemotaxonomic data allowed genotypic and phenotypic differentiation of strain NEAU-Z6T from closely related species. Thus, strain NEAU-Z6T represents a novel species of the genus Nonomuraea , for which the name Nonomuraea solani sp. nov. is proposed. The type strain is NEAU-Z6T ( = CGMCC 4.7037T = DSM 45729T).

During our previous studies we reclassified Clostridium coccoides and a number of misclassified ruminococci into a novel genus Blautia within the family Lachnospiraceae . However, the Rules of the Bacteriological Code currently require that the types of all species and subspecies with new names (including new combinations) be deposited in two different collections in two different countries. The type strain of Ruminococcus obeum was, at that period in time, only deposited in the American Type Culture Collection (ATCC) and a second independent deposit, as required by the Code, was not available. Consequently, the transfer of this species to the genus Blautia could not be made, because the resulting species name would not conform to the Rules governing the valid publication of species names and deposit of type material (Rules 27 and 30) and consequently would not be considered to be validly published. This resulted in a nomenclatural and taxonomic anomaly with R. obeum being phylogenetically placed among members of the genus Blautia with 16S rRNA gene sequence similarities of between 91.8 and 96.6 %. In order to rectify this unsatisfactory situation, through our discussions with the ATCC, the deposit of strain R. obeum ATCC 29174T to the DSMZ as strain number DSM 25238T was completed. Hence, the transfer of R. obeum to the genus Blautia as Blautia obeum comb. nov. is now proposed. The type strain is ATCC 29174T ( = DSM 25238T = KCTC 15206T).

A novel actinomycete, designated strain NEAU-FHS4T, was isolated from the root of black false hellebore (Veratrum nigrum L.). Strain NEAU-FHS4T formed single spores with smooth surfaces on substrate mycelium. The novel strain contained meso-diaminopimelic as amino acid of the peptidoglycan and xylose and glucose as whole-cell sugars. The predominant menaquinones were MK-10(H6) and MK-10(H8). Mycolic acids were not detected. The diagnostic phospholipids were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylinositol. The predominant cellular fatty acids were iso-C16 : 0, C16 : 0, C18 : 0 and anteiso-C17 : 0. Phenotypic and chemotaxonomic analysis showed that the novel isolate had characteristics typical of members of the genus Plantactinospora . 16S rRNA gene sequence analysis also indicated that strain NEAU-FHS4T belonged to the genus Plantactinospora , with highest sequence similarities to Plantactinospora mayteni YIM 61359T (98.88 %) and Plantactinospora endophytica YIM 68255T (98.85 %). The results of DNA–DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of the novel strain from the most closely related strains. Based on morphological, chemotaxonomic and phylogenetic data, strain NEAU-FHS4T is considered to represent a novel species of the genus Plantactinospora , for which the name Plantactinospora veratri sp. nov. is proposed. The type strain is NEAU-FHS4T ( = CGMCC 4.7143T = DSM 46718T).

Gene Sequence Analysis

Sixty-two strains of thermophilic aerobic endospore-forming bacteria were subjected to polyphasic taxonomic study including 16S rRNA gene sequence analysis, polar lipid and fatty acid analysis, phenotypic characterization, and DNA–DNA hybridization experiments. Distinct clusters of the species Geobacillus stearothermophilus , Geobacillus thermodenitrificans , Geobacillus toebii and Geobacillus thermoglucosidasius were formed, allowing their descriptions to be emended, and the distinctiveness of the poorly represented species Geobacillus jurassicus , Geobacillus subterraneus and Geobacillus caldoxylosilyticus was confirmed. It is proposed that the name Geobacillus thermoglucosidasius be corrected to Geobacillus thermoglucosidans nom. corrig. Bacillus thermantarcticus clustered between Geobacillus species on the basis of 16S rRNA gene sequence analysis, and its transfer to the genus Geobacillus as Geobacillus thermantarcticus comb. nov. (type strain LMG 23032T = DSM 9572T = strain M1T = R-35644T) is proposed. The above-mentioned species, together with Geobacillus thermoleovorans and Geobacillus thermocatenulatus , form a monophyletic cluster representing the genus Geobacillus . The distinctiveness of ‘Geobacillus caldoproteolyticus’ was confirmed and it is proposed that it be accommodated, along with Geobacillus tepidamans , in the genus Anoxybacillus as Anoxybacillus caldiproteolyticus sp. nov. (type strain DSM 15730T = ATCC BAA-818T = LMG 26209T = R-35652T) and Anoxybacillus tepidamans comb. nov. (type strain LMG 26208T = ATCC BAA-942T = DSM 16325T = R-35643T), respectively. The type strain of Geobacillus debilis was not closely related to any members of the genera Anoxybacillus and Geobacillus , and it is proposed that this species be placed in the new genus Caldibacillus as Caldibacillus debilis gen. nov. comb. nov. The type strain of the type species, Caldibacillus debilis, is LMG 23386T ( = DSM 16016T = NCIMB 13995T = TfT = R-35653T).

A new strain of the genus Kribbella , PIP 118T, was isolated from the leaf of an Australian native apricot tree (Pittosporum angustifolium), or Gumbi Gumbi in the indigenous language. This strain is an aerobic actinobacterium consisting of hyphae that fragment into short to elongated rod-like elements. Phylogenetic evaluation based on 16S rRNA gene sequence analysis placed this isolate as a member of the family Nocardioidaceae and most closely related to Kribbella antibiotica YIM 31530T (98.6 %) and Kribbella koreensis LM 161T (98.4 %). Chemotaxonomic data including cell wall components, major menaquinone and major fatty acids confirmed the affiliation of strain PIP 118T to the genus Kribbella . The results of the phylogenetic analysis, including physiological and biochemical studies in combination with DNA–DNA hybridization, allowed the genotypic and phenotypic differentiation of strain PIP 118T and members of the most closely related species with validly published names. The name proposed for the new species is Kribbella endophytica sp. nov. The type strain is PIP 118T ( = DSM 23718T = NRRL B-24812T).
