A Gram-negative, strictly aerobic, non-motile and non-spore-forming rod that produced white, viscous colonies, designated QHT, was isolated from bulking sludge collected from a municipal wastewater treatment plant in Beijing, China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain QHT belonged to the genus Terrimonas and shared 96.3 % sequence similarity with Terrimonas lutea DYT, 94.1 % with Terrimonas ferruginea ATCC 13524T and 93.8 % with Terrimonas aquatica RIB1-6T. Strain QHT contained iso-C15 : 0, summed feature 3 (comprising one or more of C16 : 1ω7c, C16 : 1ω6c and iso-C15 : 0 2-OH) and iso-C15 : 1 G as the predominant fatty acids. The predominant polar lipid of strain QHT and members of the genus Terrimonas was phosphatidylethanolamine. The major isoprenoid quinone of strain QHT was MK-7 and the DNA G+C content was 41.0 mol%. DNA–DNA relatedness between strain QHT and T. lutea BCRC 17944T, T. ferruginea BCRC 17943T and T. aquatica BCRC 17941T was 32, 23 and 22 %, respectively. On the basis of phylogenetic inference, differential phenotypic data and low DNA–DNA relatedness with members of the genus Terrimonas , strain QHT represents a novel species, for which the name Terrimonas pekingensis sp. nov. is proposed. The type strain is QHT ( = CICC 10452T  = NCCB 100397T). The descriptions of the genus Terrimonas and T. ferruginea , T. lutea and T. aquatica are also emended.

A Gram-stain-negative bacterium, designated strain PF-30T, was isolated from floodwater of a paddy field in South Korea. Strain PF-30T was found to be a strictly aerobic, motile and pink-pigmented rods which can grow at 25–40 °C (optimum, 28 °C), at pH 5.0–9.0 (optimum pH 7.0) and at salinities of 0.5–3.0 % NaCl (optimum 0.5 % NaCl). Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain PF-30T belongs to the genus Elioraea , showing highest sequence similarity to Elioraea tepidiphila TU-7T (97.1%) and less than 91.3 % similarity with other members of the family Acetobacteraceae . The average nucleotide identity (ANI) and DNA–DNA relatedness between the strain PF-30T and E. tepidiphila TU-7T yielded an ANI value of 75.1 % and DNA–DNA relatedness of 11.7±0.7 %, respectively. The major fatty acids were identified as C18 : 0 and C18 : 1 ω7c. The predominant respiratory quinone was identified as Q-10. The DNA G+C content was determined to be 69.9 mol%. The strain PF-30T was observed to produce plant-growth-promoting materials such as indole-3-acetic acid (IAA), siderophore and phytase. On the basis of the results from phylogenetic, chemotaxonomic and phenotypic data, we concluded that strain PF-30T represents a novel species of the genus Elioraea , for which the name Elioraea rosea sp. nov. is proposed. The type strain is PF-30T (=KACC 19985T=NBRC 113984T).

A Gram-reaction-negative, strictly aerobic, non-motile, non-spore-forming and rod-shaped bacterial strain, designated THG-45T, was isolated from soil of a ginseng field of Pocheon province in the Republic of Korea and its taxonomic position was investigated by a polyphasic approach. Growth occurred at 4–30 °C, at pH 5.5–9.0 and with 0–2 % (w/v) NaCl on nutrient agar. On the basis of 16S rRNA gene sequence similarity, strain THG-45T was shown to belong to the genus Pedobacter and was related to Pedobacter borealis G-1T (98.8 %), P. alluvionis NWER-II11T (97.9 %), P. agri PB92T (97.9 %), P. terrae DS-57T (97.5 %), P. suwonensis 15-52T (97.4 %), P. sandarakinus DS-27T (97.0 %) and P. soli 15-51T (97.0 %), but DNA relatedness between strain THG-45T and these strains was below 36 %. The G+C content of the genomic DNA was 39 mol%. The only isoprenoid quinone detected in strain THG-45T was menaquinone-7 (MK-7). The predominant fatty acids were iso-C15 : 0, summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c) and iso-C17 : 0 3-OH, and the major polar lipids were phosphatidylethanolamine and an unidentified aminophosphoglycolipid. Phenotypic data and phylogenetic inference supported the affiliation of strain THG-45T to the genus Pedobacter , and a number of biochemical tests differentiated strain THG-45T from the recognized species of the genus Pedobacter . Therefore, the novel isolate represents a novel species, for which the name Pedobacter ginsenosidimutans sp. nov. is proposed, with THG-45T as the type strain ( = KACC 14530T = JCM 16721T).

A strictly aerobic, bacteriochlorophyll (BChl) a-containing alphaproteobacterium, designated strain K6T, was isolated from seawater around an aquaculture site in the Uwa Sea in Japan. The novel strain grew optimally at 30 °C at pH 7.0–7.5 and in the presence of 2.0 % (w/v) NaCl. The nonmotile and coccoid or rod-shaped cells formed pink-pigmented colonies on agar plates containing organic compounds. Cells showed an in vivo absorption maximum at 870 nm in the near-infrared region, indicating the presence of BChl a in the light-harvesting 1 complex. The new bacterial strain was Gram-stain-negative and oxidase- and catalase-positive. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain K6T was closely related to species in the genus Litoreibacter . The closest phylogenetic relatives of strain K6T were Litoreibacter ponti GJSW-31T (98.56 % sequence similarity), Litoreibacter janthinus KMM 3842T (97.63 %) and Litoreibacter albidus KMM 3851T (96.88 %). The G+C content of the genomic DNA was 58.26 mol%. The average nucleotide identity value of strain K6T with the type strain of L. ponti was 77.16 % (SD 4.79 %). The digital DNA−DNA hybridization value of strain K6T with the type strain of L. ponti was 19.40 %. The respiratory quinone was ubiquinone-10. The major cellular fatty acids were C18 : 1 ω7c, C16 : 0 and 11-methyl C18 : 1 ω7c. The dominant polar lipids were phosphatidylcholine and phosphatidylglycerol. On the basis of the genetic and phenotypic data obtained in the present study, we propose a new species in the genus Litoreibacter : Litoreibacter roseus sp. nov., whose type strain is K6T (=DSM 110109T=NBRC 114114T). Strain K6T represents the first confirmed species that produces BChl a within the genus Litoreibacter .

A novel actinobacterium, designated strain BR-34T, was isolated from rhizosphere soil of bamboo (Phyllostachys nigro var. henonis) sampled in Damyang, Korea. The strain was found to have morphological and chemotaxonomic characteristics typical of the genus Catenulispora . The strain contained iso-C16 : 0 as the major fatty acid and MK-9(H4), MK-9(H6) and MK-9(H8) as major isoprenoid quinones. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BR-34T formed a cluster separate from members of the genus Catenulispora and was related most closely to Catenulispora acidiphila ID139908T (97.4 % similarity), Catenulispora rubra Aac-30T (97.3 %), Catenulispora yoronensis TT N02-20T (97.3 %) and Catenulispora subtropica TT 99-48T (97 %). However, the level of DNA–DNA relatedness between strain BR-34T and C. acidiphila ID139908T was only 45.32 %. Based on DNA–DNA relatedness, morphological and phenotypic data, strain BR-34T could be distinguished from the type strains of phylogenetically related species. It is therefore considered to represent a novel species of the genus Catenulispora , for which the name Catenulispora graminis sp. nov. is proposed. The type strain is BR-34T ( = KACC 15070T = NBRC 107755T).

Strain MUSC 115T was isolated from mangrove soil of the Tanjung Lumpur river in the state of Pahang, Peninsular Malaysia. Cells of this strain stained Gram-positive and were non-spore-forming, short rods that formed yellowish-white colonies on different agar media. The taxonomy of strain MUSC 115T was studied by a polyphasic approach, and the organism showed a range of phylogenetic and chemotaxonomic properties consistent with those of the genus Microbacterium . The cell-wall peptidoglycan was of type B2β, containing the amino acids ornithine, alanine, glycine, glutamic acid and homoserine. The muramic acid was of the N-glycolyl form. The predominant menaquinones detected were MK-12, MK-13 and MK-11. The polar lipids consisted of phosphatidylglycerol, phosphoglycolipid, diphosphatidylglycerol, two unidentified lipids, three unidentified phospholipids and four unidentified glycolipids. The major fatty acids of the cell membrane were anteiso-C15 : 0 and anteiso-C17 : 0. The whole-cell sugars detected were ribose, glucose, mannose and galactose. Based on the 16S rRNA gene sequence, strain MUSC 115T showed the highest sequence similarity to Microbacterium immunditiarum SK 18T (98.1 %), M. ulmi XIL02T (97.8 %) and M. arborescens DSM 20754T (97.5 %) and lower sequence similarity to strains of other species of the genus Microbacterium . DNA–DNA hybridization experiments revealed a low level of DNA–DNA relatedness (less than 24 %) between strain MUSC 115T and the type strains of closely related species. Furthermore, BOX-PCR fingerprint comparison also indicated that strain MUSC 115T represented a unique DNA profile. The DNA G+C content determined was 70.9±0.7 mol%, which is lower than that of M. immunditiarum SK 18T. Based on the combination of genotypic and phenotypic data, it is proposed that strain MUSC 115T represents a novel species of the genus Microbacterium , for which the name Microbacterium mangrovi sp. nov. is proposed. The type strain is MUSC 115T ( = MCCC 1K00251T = DSM 28240T = NBRC 110089T).
