A yellow-pigmented, Gram-stain-negative, strictly aerobic, rod-shaped, round-ended bacterium, designated strain 18-11HKT, was isolated from a phosphate mine situated in the suburb of Kunming in Yunnan province in south-western China. The taxonomic status of this strain was evaluated by using a polyphasic approach. On the basis of 16S rRNA gene sequence similarity, strain 18-11HKT was shown to belong to the genus Novosphingobium , showing the highest levels of sequence similarity with respect to ‘Novosphingobium ginsenosidimutans’ FW-6 (97.2 %), Novosphingobium subterraneum DSM 12447T (96.7 %), Novosphingobium aromaticivorans DSM 12444T (96.7 %) and Novosphingobium tardaugens DSM 16702T (96.3 %). Strain 18-11HKT had a genomic DNA G+C content of 65.3 mol% and Q-10 as the predominant respiratory quinone. DNA–DNA hybridizations of strain 18-11HKT with N. subterraneum DSM 12447T, N. aromaticivorans DSM 12444T and N. tardaugens DSM 16702T showed low relatedness values of 29.6, 33.5 and 32.3 %, respectively. The predominant fatty acids of strain 18-11HKT were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0, and the major 2-hydroxy fatty acid was C14 : 0 2-OH. The polar lipid profile revealed the presence of sphingoglycolipid, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine and some unidentified lipids. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain 18-11HKT represents a novel species of the genus Novosphingobium , for which the name Novosphingobium kunmingense sp. nov. is proposed. The type strain is 18-11HKT ( = CGMCC 1.12274T = DSM 25975T).

A strictly aerobic, thermophilic, moderately acidophilic, non-spore-forming bacterium, strain P373T, was isolated from geothermally heated soil at Waikite, New Zealand. Cells were filamentous rods, 0.2–0.4 µm in diameter and grew in chains up to 80 µm in length. On the basis of 16S rRNA gene sequence similarity, strain P373T was shown to belong to the family Chitinophagaceae (class Sphingobacteriia ) of the phylum Bacteroidetes , with the most closely related cultivated strain, Chitinophaga pinensis UQM 2034T, having 87.6 % sequence similarity. Cells stained Gram-negative, and were catalase- and oxidase-positive. The major fatty acids were i-15 : 0 (10.8 %), i-17 : 0 (24.5 %) and i-17 : 0 3-OH (35.2 %). Primary lipids were phosphatidylethanolamine, two unidentified aminolipids and three other unidentified polar lipids. The presence of sulfonolipids (N-acyl-capnines) was observed in the total lipid extract by mass spectrometry. The G+C content of the genomic DNA was 47.3 mol% and the primary respiratory quinone was MK-7. Strain P373T grew at 35–63 °C with an optimum temperature of 60 °C, and at pH 5.5–8.7 with an optimum growth pH of 7.3–7.4. NaCl tolerance was up to 5 % (w/v) with an optimum of 0.1–0.25 % (w/v). Cell colonies were non-translucent and pigmented vivid yellow–orange. Cells displayed an oxidative chemoheterotrophic metabolism. The distinct phylogenetic position and the phenotypic characteristics separate strain P373T from all other members of the phylum Bacteroidetes and indicate that it represents a novel species in a new genus, for which the name Thermoflavifilum aggregans gen. nov., sp. nov. is proposed. The type strain of the type species is P373T ( = ICMP 20041T = DSM 27268T).

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 Gram-stain-positive, strictly aerobic, spherical, non-motile red-pigmented bacterial strain, designated MJ27T, was isolated from a sludge sample of the Daejeon sewage disposal plant in South Korea. A polyphasic approach was used to study the taxonomic position of strain MJ27T. Strain MJ27T shared highest 16S rRNA gene sequence similarity with Deinococcus grandis DSM 3963T (98.8 %), Deinococcus caeni Ho-08T (97.5 %) and Deinococcus aquaticus PB314T (96.6 %.); levels of sequence similarity with the type strains of other Deinococcus species were less than 96.0 %. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MJ27T belonged to the clade formed by members of the genus Deinococcus in the family Deinococcaceae . The G+C content of the genomic DNA of strain MJ27T was 67.6 mol%. The chemotaxonomic characteristics of strain MJ27T were typical of members of the genus Deinococcus , with MK-8 as the predominant respiratory quinone, C16 : 1ω7c, C15 : 1ω6c, C16 : 0 and C15 : 0 as major fatty acids (>12 %), ornithine as the diamino acid in the cell-wall peptidoglycan and resistance to gamma radiation [D10 (dose required to reduce the bacterial population by tenfold) >9 kGy]. The low levels of DNA–DNA relatedness reported here (5.3±1.5–29.2±2.3 %) indicate that strain MJ27T represents a species that is separate from its closest relatives in the genus Deinococcus . On the basis of phylogenetic inference, fatty acid profile and other phenotypic properties, strain MJ27T is considered to represent a novel species of the genus Deinococcus , for which the name Deinococcus daejeonensis sp. nov. is proposed. The type strain is MJ27T ( = KCTC 13751T = JCM 16918T).
