A novel strain, designated HY-50RT, isolated from soil of a Euphrates poplar (Populus euphratica) forest in Xinjiang, China, was characterized using a polyphasic taxonomic approach. Cells of the isolate were Gram-reaction-negative, strictly aerobic, rod-shaped, non-motile, oxidase-negative and catalase-positive. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate was a member of the phylum Bacteroidetes, its closest relatives being Niastella populi THYL-44T (93.6 % similarity), Flavisolibacter ginsengisoli Gsoil 643T (93.5 %), Terrimonas ferruginea IAM 15098T (93.3 %) and Flavisolibacter ginsengiterrae Gsoil 492T (93.2 %). The major fatty acids were iso-C15 : 1 G (11.7 %), iso-C15 : 0 (19.6 %) and iso-C17 : 0 3-OH (19.3 %). The predominant menaquinone of strain HY-50RT was MK-7 and the genomic DNA G+C content was 46.8 mol%. Flexirubin-type pigments were not produced. Based on phylogenetic evidence and the results of phenotypic, genotypic and chemotaxonomic analysis, strain HY-50RT represents a novel species of a novel genus, for which the name Flavitalea populi gen. nov., sp. nov. is proposed. The type strain is HY-50RT ( = CCTCC AB 208255T  = NRRL B-59222T).

A light-pink-coloured bacterium, designated strain 5416T-32T, was isolated from an air sample in Korea. Cells of the strain were strictly aerobic, Gram-negative, motile (single polar or subpolar flagellum) and rod-shaped. Optimal growth occurred at 25–30 °C and at pH 6.0–7.0. The major quinones were Q-10 and Q-8. The major fatty acids were C18 : 1 ω7c (53.8 %) and C16 : 0 (15.9 %). The G+C content of the genomic DNA was 65.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 5416T-32T was most closely related to Skermanella parooensis, with a similarity of 96.2 %, but relatively low sequence similarities (<92 %) were found with respect to other species with validly published names held in GenBank. Phenotypic and genotypic analyses indicated that strain 5416T-32T could not be assigned to any recognized species. Therefore strain 5416T-32T represents a novel species of the genus Skermanella, for which the name Skermanella aerolata sp. nov. is proposed. The type strain is 5416T-32T (=KACC 11604T=DSM 18479T).

A Gram-positive, aerobic, non-spore-forming actinobacterial strain, designated strain TL1T, was isolated from pig manure in Wuhan, China. The cell wall peptidoglycan contained meso-diaminopimelic acid. The major polar lipids were phosphatidylethanolamine, phosphatidylinositol and diphosphatidylglycerol. The predominant menaquinone was MK-8(H4). The major fatty acids (>10 %) were iso-C16 : 0, iso-C15 : 0 and C17 : 1ω8c. The genomic DNA G+C content was 70.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain TL1T was most closely related to the type strains of Knoellia sinensis (98.5 %), Knoellia subterranea (98.2 %) and Knoellia aerolata (96.9 %). DNA–DNA relatedness values of strain TL1T with the type strains of K. sinensis and K. subterranea were 27.3 and 34.0 %, respectively. Comparison of phenotypic, chemotaxonomic and phylogenetic characteristics among strain TL1T and related organisms revealed that the isolate represents a novel species of the genus Knoellia, for which the name Knoellia flava sp. nov. is proposed; the type strain is TL1T ( = CGMCC 1.10749T = KCTC 19810T).

A novel strain, designated 311-10T, isolated from soil of Xinjiang, China, was characterized by using a polyphasic taxonomic approach. The isolate was Gram-negative, aerobic, rod-shaped, non-motile, oxidase-negative and catalase-positive. The predominant menaquinone of strain 311-10T was MK-7 and the genomic DNA G+C content was 47.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate formed a cluster with the genera Pontibacter and [Effluviibacter] in the phylum ‘Bacteroidetes’, with sequence similarities of 93.9–95.6 %. Phylogenetic evidence and the results of phenotypic, genotypic and chemotaxonomic analyses support the reclassification of [Effluviibacter] roseus as Pontibacter roseus comb. nov. (type strain, SRC-1T=MTCC 7260T=DSM 17521T) and the establishment of a novel species, Pontibacter xinjiangensis sp. nov., with strain 311-10T (=CCTCC AB 207200T=NRRL B-51335T) as the type strain.

Two sporulating bacterial strains designated CECAP06T and CECAP16 were isolated from the rhizosphere of the legume Cicer arietinum in Argentina. Almost-complete 16S rRNA gene sequences identified the isolates as a Paenibacillus species. It was most closely related to Paenibacillus cineris LMG 18439T (99·6 % sequence similarity), Paenibacillus favisporus LMG 20987T (99·4 % sequence similarity) and Paenibacillus azoreducens DSM 13822T (97·7 % sequence similarity). The cells of this novel species were motile, sporulating, rod-shaped, Gram-positive and strictly aerobic. The predominant fatty acids were anteiso-C15 : 0, C16 : 0 and iso-C16 : 0. The DNA G+C content of strains CECAP06T and CECAP16 was 51·3 and 50·9 mol%, respectively. Growth was observed from many carbohydrates, but gas production was not observed from glucose. Catalase and oxidase activities were present. The isolates produced β-galactosidase and hydrolysed aesculin. Gelatinase, caseinase and urease were not produced. The results of DNA–DNA hybridization showed that the strains from this study constitute a novel species of the genus Paenibacillus, for which the name Paenibacillus rhizosphaerae sp. nov. is proposed. The type strain is CECAP06T (=LMG 21955T=CECT 5831T).
