A second novel clinical actinobacterial strain, designated IFM 10348T, was isolated from the sputum of the same Japanese patient with bacterial pneumonia from whom the type strain of Gordonia araii had been isolated. The strains differed in phylogenetic position and drug-resistance profiles. The taxonomic position of strain IFM 10348T was clarified by phenotypic, chemotaxonomic and phylogenetic studies. Phylogenetic analyses based on 16S rRNA gene sequences clearly demonstrated that strain IFM 10348T occupied a distinct clade within the genus Gordonia and was related closely to Gordonia malaquae DSM 45064T and Gordonia hirsuta DSM 44140T (97.3 and 97.1 % similarities, respectively). Strain IFM 10348T was also clearly differentiated from G. malaquae DSM 45064T and G. hirsuta DSM 44140T based on gyrB and secA1 gene sequence similarity values. Strain IFM 10348T had MK-9(H2) as the predominant menaquonine, contained meso-diaminopimelic acid, arabinose, galactose and glucosamine as cell-wall components, and contained C18 : 1ω9c, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0 as the major cellular fatty acids. Mycolic acids were present. The DNA G+C content of strain IFM 10348T was 68.0 mol%. DNA–DNA relatedness data coupled with the combination of genotypic and phenotypic data indicated that strain IFM 10348T represents a novel species of the genus Gordonia , for which the name Gordonia iterans sp. nov. is proposed. The type strain is IFM 10348T ( = CCTCC M2011245T = NCCB 100436T).

Strain HNM0947T, representing a novel actinobacterium, was isolated from the coral Galaxea astreata collected from the coast of Wenchang, Hainan, China. The strain was found to have morphological and chemotaxonomic characteristics consistent with the genus Nocardiopsis . The organism formed abundant fragmented substrate mycelia and aerial mycelia which differentiated into non-motile, rod-shaped spores. Whole-cell hydrolysates contained meso-diaminopimelic acid and no diagnostic sugars. The major menaquinones were MK-10(H8), MK-10(H6) and MK-10(H4). The major phospholipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The major fatty acids were iso-C16:0, anteiso-C17:0, C18:0, C18:0 10-methyl (TBSA) and anteiso-C15:0. The G+C content was 71.3 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain HNM0947T belonged to the genus Nocardiopsis and shared highest sequence similarity to Nocardiopsis salina YIM 90010T (98.8%), Nocardiopsis xinjiangensis YIM 90004T(98.5%) and Nocardiopsis kunsanensis DSM 44524T (98.3%). The strain HNM0947T was distinguished from its closest type strain by low average nucleotide identity (90.8%) and dDDH values (60.4%) respectively. Based on genotypic, chemotaxonomic and phenotypic characteristics, it was concluded that strain HNM0947T represents a novel species of the genus Nocardiopsis whose name was proposed as Nocardiopsis coralli sp. nov. The type strain was HNM0947T (=CCTCC AA 2020015 T=KCTC 49525 T).

A novel actinomycete, designated strain KT2025T, was isolated from arid soil collected from Magusa, northern Cyprus. The taxonomic position of the novel strain was established by using a polyphasic approach. The organism had chemical and morphological features consistent with its classification in the genus Amycolatopsis . Phylogenetic analyses based on 16S rRNA gene sequences supported the classification of the isolate in the genus Amycolatopsis and showed that the organism formed a cluster with Amycolatopsis nigrescens CSC17-Ta-90T, Amycolatopsis minnesotensis 32U-2T, Amycolatopsis sacchari DSM 44468T and Amycolatopsis dongchuanensis YIM 75904T. 16S rRNA gene sequence similarity analysis indicated that strain KT2025T was most closely related to Amycolatopsis lurida DSM 43134T (97.5 %), Amycolatopsis keratiniphila subsp. keratiniphila DSM 44409T (97.4 %), Amycolatopsis keratiniphila subsp. nogabecina DSM 44586T (97.1 %), Amycolatopsis nigrescens DSM 44992T (97.1 %), Amycolatopsis azurea DSM 43854T (97.1 %) and Amycolatopsis minnesotensis DSM 44988T (96.9 %). The organism was found to have chemical features typical of members of the genus Amycolatopsis such as meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, and arabinose and galactose as diagnostic sugars. The predominant menaquinone was MK-9(H4). The polar lipids detected were phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and hydroxy-phosphatidylethanolamine. The major fatty acids were iso-C16 : 0, iso-C15 : 0 and iso-C14 : 0. The G+C content of the genomic DNA was 70.8 mol%. Phenotypic data clearly distinguished the isolate from its closest relatives. The combined genotypic and phenotypic data and low levels of DNA–DNA relatedness with its closest relatives indicated that strain KT2025T represents a novel species of the genus Amycolatopsis , for which the name Amycolatopsis magusensis sp. nov. is proposed. The type strain is KT2025T ( = DSM 45510T = KCTC 29056T).

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.

Four aerobic, Gram-stain-positive, rod-shaped bacteria (HY60T, HY54, HY82T and HY89) were isolated from bat faeces of Hipposideros and Rousettus species collected in PR China. Phylogenetic analyses based on 16S rRNA gene sequences indicated that the four novel strains formed two separate but adjacent subclades close to Microbacterium agarici CGMCC 1.12260T (97.6–97.7 % similarity), Microbacterium humi JCM 18706T (97.3–97.5 %) and Microbacterium lindanitolerans JCM 30493T (97.3–97.4 %). The 16S rRNA gene sequence similarity was 98.3 % between strains HY60T and HY82T, and identical within strain pairs HY60T/HY54 and HY82T/HY89. The DNA G+C contents of strains HY60T and HY82T were 61.9 and 63.3 mol%, respectively. The digital DNA–DNA hybridization and average nucleotide identity values between each novel strain and their closest relatives were all below the 70 % and 95–96 % thresholds for species delimitation, respectively. All four novel strains contained anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and iso-C15 : 0 as the main fatty acids, MK-11 and MK-12 as the major respiratory quinones, and diphosphatidylglycerol, phosphatidylglycerol and one unidentified glycolipid as the predominant polar lipids. The cell-wall peptidoglycan was of B type and contained alanine, glutamate, glycine and ornithine. The acyl type of the muramic acid was glycolyl. The whole-cell sugars were rhamnose and ribose. Based on the foregoing polyphasic analyses, it was concluded that the four uncharacterized strains represented two novel species of the genus Microbacterium , for which the names Microbacterium chengjingii sp. nov. [type strain HY60T (=CGMCC 1.17468T=GDMCC 1.1951T=KACC 22102T)] and Microbacterium fandaimingii sp. nov. [type strain HY82T (=CGMCC 1.17469T=GDMCC 1.1949T=KACC 22101T)] are proposed, respectively.

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 .

Two Gram-stain-negative, aerobic, moderately halophilic, rod-shaped bacteria (strains Ar-45T and DY470T) were isolated from seawater collected from the Southern Ocean and the Pacific Ocean, respectively. Growth of strain Ar-45T was observed with between 0.5 and 10.0 % (w/v) NaCl (optimally with 0.5–3.0 %) and between pH 5.5 and 9.5. Strain DY470T grew in the presence of 0.5–7.5 % (w/v) NaCl (optimally with 2.0 %) and at pH 5.5–8.5. Chemotaxonomic analysis showed Q-10 as the respiratory quinone for both strains. The major fatty acids (>5 %) of strain Ar-45T were C16 : 0, C19 : 0 cyclo ω8c and C18 : 1ω7c, while those of strain DY470T were C18 : 1ω7c, C16 : 0 and 11-methyl C18 : 1ω7c. The DNA G+C contents of the two strains were 62.0 and 61.8 mol%, respectively. Phylogenetic analyses based on 16S rRNA gene sequences showed that strains Ar-45T and DY470T were related most closely to the genus Oceanicola , with sequence similarities of 97.4–94.0 and 97.7–94.7 %, respectively. The DNA–DNA hybridization value between strain Ar-45T and Oceanicola marinus LMG 23705T was 22.0 %. Levels of DNA–DNA relatedness between strain DY470T and Oceanicola nitratireducens LMG 24663T and Oceanicola batsensis DSM 15984T were 32.5 and 26.1 %, respectively. Based on phylogenetic, chemotaxonomic and phenotypic data, strains Ar-45T and DY470T are considered to represent two novel species of the genus Oceanicola , for which the names Oceanicola antarcticus (type strain Ar-45T = CGMCC 1.12662T = LMG 27868T) and Oceanicola flagellatus (type strain DY470T = CGMCC 1.12664T = LMG 27871T) are proposed.

Root-nodule bacteria were isolated from Inga laurina (Sw.) Willd. growing in the Cerrado Amazon region, State of Roraima, Brazil. The 16S rRNA gene sequences of six strains (BR 10250T, BR 10248, BR 10249, BR 10251, BR 10252 and BR 10253) showed low similarities with currently described species of the genus Bradyrhizobium . Phylogenetic analyses of sequences of five housekeeping genes (dnaK, glnII, gyrB, recA and rpoB) revealed Bradyrhizobium iriomotense EK05T to be the closest type strain (97.4 % sequence similarity or less). Chemotaxonomic data, including fatty acid profiles [with the major components C16 : 0 and summed feature 8 (C18 : 1ω6c/C18 : 1ω7c)], the slow growth rate and carbon compound utilization patterns supported the assignment of our strains to the genus Bradyrhizobium . Results from DNA–DNA hybridizations and physiological traits differentiated our strains from the closest related species of the genus Bradyrhizobium with validly published names. Sequences of symbiosis-related genes for nodulation (nodC) and nitrogen fixation (nifH) grouped together with those of B. iriomotense EK05T and Bradyrhizobium sp. strains BR 6610 (used as a commercial inoculant for Inga marginata in Brazil) and TUXTLAS-10 (previously observed in Central America). Based on these data, the six strains represent a novel species, for which the name Bradyrhizobium ingae sp. nov. is proposed. The type strain is BR 10250T ( = HAMBI 3600T).

A Gram-stain-negative, motile bacterium, designated strain YE3T, was isolated from activated sludge obtained from a municipal wastewater treatment plant in Daejeon Metropolitan City, Republic of Korea. The cells were oxidase- and catalase-positive, and grew under aerobic conditions at 10–40 °C (optimum, 30 °C), with 1.0–8.0 % (w/v) NaCl (1.0 %) and at pH 5.5–9.0 (pH 7.0). Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain YE3T was most closely related to Pusillimonas harenae KACC 14927T (98.2 % sequence similarity) and Pusillimonas ginsengisoli KCTC 22046T (98.0 %). DNA–DNA relatedness values for strain YE3T and P. harenae KACC 14927T, P. ginsengisoli KCTC 22046T and P. soli KCTC 22455T were 28.7±2.27 %, 21.3±1.16 %, and 14.0±0.67 %, respectively. The genomic G+C content of the type strain YE3T was 59.3 mol%, as determined by whole-genome sequencing. The dominant fatty acids were C16 : 0 (39.2 %) and C17 : 0cyclo (37.5 %). The major polar lipids of strain YE3T were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. Two aminophospholipids and four unidentified lipids were also detected. Furthermore, strain YE3T was able to oxidize thiosulfate under heterotrophic conditions. Based on the phenotypic, genotypic, chemotaxonomic and phylogenetic analyses, strain YE3T represents a novel species of the genus Pusillimonas , for which the name Pusillimonas thiosulfatoxidans sp. nov. is proposed. The type strain is YE3T (=KCTC 62737T=NBRC 113113T).
