A novel Gram-stain-negative, rod-shaped, non-flagellated, strictly aerobic strain with gliding motility, designated XH134T, was isolated from surface seawater of the South Pacific Gyre (45° 58′ S 163° 11′ W) during the Integrated Ocean Drilling Program Expedition 329. The major respiratory quinone of strain XH134T was MK-6. The dominant fatty acids of strain XH134T were iso-C15 : 0, iso-C15 : 1 G, C16 : 1ω6c and/or C16 : 1ω7c, iso-C17 : 0 3-OH, iso-C15 : 0 3-OH and 10-methyl C16 : 0 and/or iso-C17 : 1ω9c. The polar lipids of strain XH134T comprised phosphatidylethanolamine, one unknown aminolipid and three unknown polar lipids. The DNA G+C content of strain XH134T was 32.4 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that the novel strain was related most closely to Aquimarina macrocephali JAMB N27T with 96.9 % sequence similarity. A number of phenotypic characteristics distinguished strain XH134T from described members of the genus Aquimarina . On the basis of combined phenotypic and phylogenetic analyses, strain XH134T represents a novel species of the genus Aquimarina , for which the name Aquimarina megaterium sp. nov. is proposed. The type strain is XH134T ( = CGMCC 1.12186T = JCM 18215T).

A novel Gram-stain-negative, strictly aerobic, rod-shaped, brick red-pigmented bacterium, designated R-22-1 c-1T, was isolated from water from Baiyang Lake, Hebei Province, PR China. The strain was able to grow at 20–30 °C (optimum, 30 °C) and pH 6–7 (optimum, pH 6) in Reasoner’s 2A medium. 16S rRNA gene sequence and phylogenetic analyses of R-22-1 c-1T revealed closest relationships to Rufibacter immobilis MCC P1T (97.8 %), Rufibacter sediminis H-1T (97.9 %) and Rufibacter glacialis MDT1-10-3T (97.0 %), with other species of the genus Rufibacter showing less than 97.0 % sequence similarity. The predominant polar lipids were phosphatidylethanolamine, two unidentified aminophospholipids and three unidentified lipids. The major cellular fatty acids were iso-C15 : 0, C15 : 1  ω6c, C17 : 1  ω6c, anteiso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1  ω7c and/or C16 : 1  ω6c) and summed feature 4 (iso-C17 : 1I and/or anteiso-C17 : 1B). The respiratory quinone was MK-7. The draft genome of R-22-1 c-1T was 5.6 Mbp in size, with a G+C content of 50.2 mol%. The average nucleotide identity and digital DNA–DNA hybridization relatedness values between strain R-22-1 c-1T and related type strains were R. immobilis MCC P1T (77.2 and 21.8 %), R. sediminis H-1T (81.6 and 21.4 %) and R. tibetensis 1351T (78.5 and 22.9 %). Based on these phylogenetic, chemotaxonomic and genotypic results, strain R-22-1 c-1T represents a novel species in the genus Rufibacter , for which the name Rufibacter latericius sp. nov. is proposed. The type strain is R-22-1 c-1T (=CGMCC 1.13570T=KCTC 62781T).

A pink-pigmented, non-motile, Gram-stain-negative, rod-shaped bacterium, designated RP-2-7T, was obtained from soil sampled at the Arctic station, Spitsbergen, Svalbard, Norway. Cells were strictly aerobic, psychrotolerant, grew optimally at 15–20 °C and hydrolysed CM-cellulose. Phylogenetic analysis based on its 16S rRNA gene sequence revealed that strain RP-2-7T formed a lineage within the family Hymenobacteraceae and clustered with members of the genus Hymenobacter . Its closest relative was Hymenobacter marinus KJ035T (97.6 % sequence similarity). The sequence similarities to other strains were ≤96.9 %. The principal respiratory quinone was MK-7 and the major polar lipids were phosphatidylethanolamine and an unidentified aminophospholipid. The predominant cellular fatty acids were summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c), anteiso-C15 : 0, iso-C15 : 0, C16 : 1  ω5c and summed featured 4 (iso-C17 : 1 I and/or anteiso-C17 : 1 B). The DNA G+C content was 62.8 mol%. In addition, the average nucleotide identity and in silico DNA–DNA hybridization relatedness values between strain RP-2-7T and closely related strains were lower than species demarcation thresholds. Based on the resuls of genomic, chemotaxonomic, phenotypic and phylogenetic analyses, strain RP-2-7T represents novel species in the genus Hymenobacter , for which the name Hymenobacter polaris sp. nov. is proposed.

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.

Two novel strains (HMF3257T and HMF4905T), isolated from freshwater and bark samples, were investigated to determine their relationships within and between species of the genus Spirosoma by using a polyphasic approach. They were aerobic, Gram-stain-negative, non-motile and rod-shaped bacteria. The major fatty acids (>10%) in both strains were identified as summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c) and C16 : 1 ω5c, while strains HMF3257T and HMF4905T contained a moderately high amount of C16 : 0 and iso-C15 : 0, respectively. The predominant respiratory quinone was MK-7 for both strains. In addition to phosphatidylethanolamine and one unidentified glycolipid, the polar lipid profile of strain HMF3257T consisted of three unidentified aminophospholipids, one unidentified aminolipid and two unidentified polar lipids, and that of strain HMF4905T consisted of one unidentified aminophospholipid, two unidentified aminolipids and three unidentified polar lipids. The DNA G+C contents of strains HMF3257T and HMF4905T were 47.2 and 46.4 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains HMF3257T and HMF4905T are closely related to Spirosoma migulaei 15J9-8T (97.0 % sequence similarity), while sharing 97.4 % sequence similarity with each other. The average nucleotide identity value between strains HMF3257T and HMF4905T was 81.1 %, and the digital DNA–DNA hybridization value between these two strains was 24.4 %. Based on the above data, strains HMF3257T and HMF4905T represent two novel members within the genus Spirosoma , for which the names Spirosoma telluris sp. nov. and Spirosoma arboris sp. nov. are proposed, respectively. The type strain of S. telluris is HMF3257T (=KCTC 62463T=NBRC 112670T) and type strain of S. arboris is HMF4905T (=KCTC 72779T=NBRC 114270T).

The polar lipids of strain ARSA-19T were phosphatidylethanolamine, four unknown aminolipids and two unidentified polar lipids. The DNA G+C content of strain ARSA-19T was 33.3 mol%. Based on its phenotypic and genotypic characteristics and on the phylogenetic evidence presented, strain ARSA-19T is considered to represent a novel species in the genus Flavobacterium , for which the name Flavobacterium dankookense sp. nov. is proposed. The type strain is ARSA-19T ( = KCTC 23179T  = JCM 17065T  = KACC 14968T).
