A Gram-staining-negative, rod-shaped and motile bacterium, designated strain ERB1-3T, was isolated from a laboratory-scale activated sludge system treating coke plant effluent using thiocyanate-supplemented growth medium. Strain ERB1-3T was oxidase-positive and weakly catalase-positive. The predominant fatty acids were C18 : 1ω7c (35.6 %) and C17 : 1ω6c (29.2 %), and the major respiratory quinone was Q-10. Polar lipids were dominated by sphingoglycolipid and phosphatidylglycerol. Major polyamines were spermidine and sym-homospermidine. The G+C content of the genomic DNA of strain ERB1-3T was 66.4 mol%. Based on the 16S rRNA gene, strain ERB1-3T exhibited the highest sequence similarity values to Sphingomonas sanxanigenens DSM 19645T (96.1 %), Sphingobium scionense DSM 19371T (95.1 %) and Stakelama pacifica LMG 24686T (94.8 %) within the family Sphingomonadaceae . The novel isolate had some unique chemotaxonomic features that differentiated it from these closely related strains, contained much more C17 : 1ω6c, C15 : 0 2-OH, C17 : 0 and C17 : 1ω8c fatty acids and possessed diphosphatidylglycerol only in trace amounts. On the basis of the phenotypic, chemotaxonomic and molecular data, strain ERB1-3T is considered to represent a novel genus and species, for which the name Hephaestia caeni gen. nov., sp. nov. is proposed. The type strain is ERB1-3T ( = DSM 25527T = NCAIM B 02511T).

A novel Gram-reaction-negative, yellow-pigmented, aerobic, non-motile and rod-shaped bacterium designated strain CC-YHH031T was isolated from an agricultural soil collected at Chiayi County, Taiwan. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CC-YHH031T formed a discrete monophyletic lineage in the family Xanthomonadaceae , sharing high pairwise sequence similarity of 93.5–95.2 and 94.8 % with species of the genus Dokdonella (94.9 % similarity to the type strain of the type species) and Aquimonas voraii GPTSA 20T, respectively. The genomic DNA G+C content of strain CC-YHH031T was 68.6±0.7 mol% and the predominant respiratory quinone was ubiquinone Q-8. Spermidine was the principal polyamine, with minor amounts of putrescine. Major fatty acids (>5 % of total fatty acids) were iso-C16 : 0, iso-C15 : 0, C16 : 1ω7c and/or C16 : 1ω6c (summed feature 3), iso-C17 : 1ω9c, iso-C14 : 0, iso-C11 : 0 and iso-C11 : 0 3-OH. The polar lipid profile of strain CC-YHH031T included phosphatidylethanolamine, phosphatidylmonomethylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, two unidentified aminophospholipids (APL1–2) and four unidentified phospholipids (PL1–4). Strain CC-YHH031T was distinguished particularly from the type species of the genus Dokdonella ( Dokdonella koreensis ) by the presence of major amounts of iso-C14 : 0 and summed feature 3 and minor amounts of iso-C17 : 0 and by the complete absence of anteiso-C17 : 0, the presence of PL1–3 and APL1–2, the absence of APL3 and the presence of putrescine in the former. On the basis of distinguishing genotypic and phenotypic evidence, strain CC-YHH031T is proposed to represent a novel genus and species within the family Xanthomonadaceae , for which the name Chiayiivirga flava gen. nov., sp. nov. is proposed. The type strain of Chiayiivirga flava is CC-YHH031T ( = BCRC 80273T = DSM 24163T).

A novel Gram-stain-negative, aerobic, gliding, rod-shaped and carotenoid-pigmented bacterium, designated A20-9T, was isolated from a microbial consortium of polyethylene terephthalate enriched from a deep-sea sediment sample from the Western Pacific. Growth was observed at salinities of 1–8 %, at pH 6.5–8 and at temperatures of 10–40 °C. The results of phylogenetic analyses based on the genome indicated that A20-9T formed a monophyletic branch affiliated to the family Schleiferiaceae , and the 16S rRNA gene sequences exhibited the maximum sequence similarity of 93.8 % with Owenweeksia hongkongensis DSM 17368T, followed by similarities of 90.4, 90.1 and 88.8 % with Phaeocystidibacter luteus MCCC 1F01079T, Vicingus serpentipes DSM 103558T and Salibacter halophilus MCCC 1K02288T, respectively. Its complete genome size was 4 035 598 bp, the genomic DNA G+C content was 43.2 mol%. Whole genome comparisons indicated that A20-9T and O. hongkongensis DSM 17368T shared 67.8 % average nucleotide identity, 62.7 % average amino acid identity value, 46.6% of conserved proteins and 17.8 % digital DNA–DNA hybridization identity. A20-9T contained MK-7 as the major respiratory quinone. Its major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phospatidylcholine; and the major fatty acids were iso-C15 : 0 (37.5 %), iso-C16 : 0 3-OH (12.4 %), and summed feature 3 (C16 : 1ω7c /C16 : 1ω6c, 11.6 %). Combining the genotypic and phenotypic data, A20-9T could be distinguished from the members of other genera within the family Schleiferiaceae and represents a novel genus, for which the name Croceimicrobium hydrocarbonivorans gen. nov., sp. nov. is proposed. The type strain is A20-9T (=MCCC 1A17358T =KCTC 72878T).

A Gram-staining-negative, rod-shaped, gliding and pale-pink-pigmented bacterium, designated strain ZLM-10T, was isolated from a soil sample collected from an arid area in Xinjiang province, China, and characterized in a taxonomic study using a polyphasic approach. The novel strain grew optimally at 30–37 °C and in the presence of 2 % (w/v) sea salts. The only respiratory quinone detected was MK-7 and the major cellular fatty acids were summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), iso-C15 : 0 and iso-C17 : 0 3-OH. The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, an unidentified aminolipid and two unidentified aminophospholipids. The DNA G+C content was 45.4 mol%. Flexirubin-type pigments were not produced. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain ZLM-10T was a member of the phylum Bacteroidetes and appeared most closely related to Cesiribacter roseus 311T (90.2 % sequence similarity), Marivirga sericea LMG 13021T (89.2 %), Cesiribacter andamanensis AMV16T (89.1 %) and Marivirga tractuosa DSM 4126T (89.1 %). On the basis of phenotypic and genotypic data and phylogenetic inference, strain ZLM-10T should be classified as a novel species of a new genus in the family Flammeovirgaceae , for which the name Nafulsella turpanensis gen. nov., sp. nov. is proposed. The type strain of the type species is ZLM-10T ( = CCTCC AB 208222T = KCTC 23983T).

Two strains of the family Rhodospirillaceae were isolated from the rhizosphere of the medicinal plant Hypericum perforatum. Cells of both strains were Gram-stain-negative, motile by means of a single polar flagellum, non-spore-forming, non-capsulated, short rods that divided by binary fission. Colonies were small and white. Strains R5913T and R5959T were oxidase-positive, mesophilic, neutrophilic and grew optimally without NaCl. Both grew under aerobic and microaerophilic conditions and on a limited range of substrates with best results on yeast extract. Major fatty acids were C19 : 0 cyclo ω8c and C16 : 0; in addition, C18 : 1ω7c was also found as a predominant fatty acid in strain R5913T. The major respiratory quinone was ubiquinone 10 (Q-10). The DNA G+C contents of strains R5913T and R5959T were 66.0 and 67.4 mol%, respectively. 16S rRNA gene sequence comparison revealed that the closest relatives (<92 % similarity) of the strains are Oceanibaculum pacificum MCCC 1A02656T, Dongia mobilis CGMCC 1.7660T, Dongia soli D78T and Dongia rigui 04SU4-PT. The two novel strains shared 98.6 % sequence similarity and represent different species on the basis of low average nucleotide identity of their genomes (83.8 %). Based on the combined phenotypic, genomic and phylogenetic investigations, the two strains represent two novel species of a new genus in the family Rhodospirillaceae , for which the name Hypericibacter gen. nov. is proposed, comprising the type species Hypericibacter terrae sp. nov. (type strain R5913T=DSM 109816T=CECT 9472T) and Hypericibacter adhaerens sp. nov. (type strain R5959T=DSM 109817T=CECT 9620T).

A prosthecate bacterial strain, designated G-192T, was isolated from decaying biomass of a haloalkaliphilic cyanobacterium Geitlerinema sp. Z-T0701. The cells were aerobic, Gram-negative, non-endospore-forming and dimorphic, occurring either as sessile bacteria with a characteristic stalk or as motile flagellated cells. The strain utilized a limited range of substrates, mostly peptonaceous, but was able to degrade whole proteins. Growth occurred at 5–46 °C (optimum, 35–40 °C), pH 7.3–10.3 (optimum, pH 8.0–9.0), 0–14 % NaCl (v/w; optimum, 2.0–6.0 %, v/w). The G+C content of the genomic DNA of strain G-192T was 66.8%. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain G-192T formed a distinct evolutionary lineage within the family Hyphomonadaceae . Strain G-192T showed the highest 16S rRNA sequence similarity to Glycocaulis profundi ZYF765T (95.2%), Oceanicaulis stylophorae GISW-4T (94.2%) and Marinicauda salina WD6-1T (95.5%). The major cellular fatty acids (>5% of the total) were C18:1 ω9c, C18:0 and 11-methyl-C18:1 ω7c. The major polar lipids were glycolipids and phospholipids. The only respiratory quinone was ubiquinone-10 (Q-10). Based on polyphasic results including phylogenomic data, the novel strain could be distinguished from other genera, which suggests that strain G-192T represents a novel species of a new genus, for which the name Alkalicaulis satelles gen. nov., sp. nov. is proposed. The type strain is G-192T (=VKM B-3306T=KCTC 72746T). The strain is the first representative of the stalked bacteria associated with a haloalkaliphilic cyanobacterium. Based on phylogenomic indices and phenotypic data, it is proposed to evolve two novel families Maricaulaceae fam. nov. and Robiginitomaculaceae fam. nov. out of the current family Hyphomonadaceae . In addition, it is proposed to place the first two families in the novel order Maricaulales ord. nov. and novel order Hyphomonadales ord. nov. is proposed to accommodate the family Hyphomonadaceae .

Two facultatively anaerobic mesophilic bacteria, strains MEBiC 07026T and MEBiC 08903T, were isolated from two different tidal flat sediments and both strains showed approximately 92.2 % 16S rRNA gene sequence similarity with [Cytophaga] fermentans DSM 9555T. 16S rRNA gene sequence similarity between the two new isolates was 97.5 % but levels of DNA–DNA relatedness between the two were 31.3–31.8 %. Phylogenetic analysis revealed that the two isolates and [Cytophaga] fermentans DSM 9555T were affiliated with the family Marinilabiliaceae in the class Bacteroidia . The dominant fatty acids of strains MEBiC 07026T, MEBiC 08903T and [Cytophaga] fermentans DSM 9555T were branched-type or hydroxylated C15 : 0, but [Cytophaga] fermentans DSM 9555T contained a higher proportion of anteiso-branched fatty acids. The two new isolates contained a markedly higher proportion of monounsaturated fatty acids than other members of the family Marinilabiliaceae . The major respiratory quinone of the strains was MK-7. Strains MEBiC07026T and MEBiC08903T utilized a wide range of carboxylic acids whereas [Cytophaga] fermentans DSM 9555T utilized carbohydrates rather than carboxylic acids. The DNA G+C content of the novel strains was about 44 mol% but that of [Cytophaga] fermentans DSM 9555T revealed from the genome sequence was 37.6 mol%. Based on evidence from this polyphasic taxonomic study, a novel genus, Carboxylicivirga gen. nov., is proposed in the family Marinilabiliaceae with two novel species, Carboxylicivirga mesophila sp. nov. with type strain MEBiC 07026T ( = KCCM 42978T = JCM 18290T) and Carboxylicivirga taeanensis sp. nov. with type strain MEBiC 08903T ( = KCCM 43024T = JCM 19490T). Additionally, [Cytophaga] fermentans DSM 9555T ( = ATCC 19072T) is reclassified as Saccharicrinis fermentans gen. nov., comb. nov.

A strain of thermotolerant actinomycete, designated YIM 75948T, was isolated from a soil sample in Yunnan province, China. The strain grew at 25–55 °C (optimum 37 °C). The substrate mycelium and aerial mycelium produced on Czapek’s agar were both pale yellow to white. The diagnostic diamino acid of the cell-wall peptidoglycan was meso-diaminopimelic acid, and the whole-cell sugars were mannose, ribose, glucose, galactose and arabinose. The major fatty acids were iso-C15 : 0, iso-C16 : 0 and C16 : 0 and the predominant respiratory quinone was MK-9(H4). The polar lipids consisted of phosphatidylethanolamine, phosphatidylethanolamine with hydroxy fatty acids, diphosphatidylglycerol, phosphatidylinositol and two unidentified phospholipids. The genomic DNA G+C content was 73.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YIM 75948T belonged in the genus Actinokineospora and that its closest relative among recognized species was Actinokineospora fastidiosa DSM 43855T (97.6 % sequence similarity). The mean level of DNA–DNA relatedness between the novel strain and A. fastidiosa DSM 43855T was, however, only 47.8 %. Based on the phenotypic, chemotaxonomic and phylogenetic data and the results of the DNA–DNA hybridizations, strain YIM 75948T represents a novel species of the genus Actinokineospora for which the name Actinokineospora soli sp. nov. is proposed. The type strain is YIM 75948T ( = JCM 17695T = DSM 45613T). The description of the genus Actinokineospora is emended to reflect the fact that the genomic DNA G+C contents of A. fastidiosa DSM 43855T and the type strain of Actinokineospora soli sp. nov. recorded in the present study fell above the range given in previous descriptions of this genus.

A Gram-negative bacterium, designated DCY13T, was isolated from soil of a ginseng field in South Korea. Comparative analysis of 16S rRNA gene sequences showed that strain DCY13T shared the highest sequence similarity (95.0 %) with Sediminibacterium salmoneum NBRC 103935T and 87.6–91.4 % sequence similarity with other members of the family Chitinophagaceae . Cells were non-spore-forming rods, catalase- and oxidase-positive, motile by gliding and facultatively anaerobic. The only respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids were iso-C17 : 0 3-OH, iso-C15 : 0 and iso-C15 : 1 G. The G+C content of the genomic DNA was 47.5±1.0 mol%. In addition to phosphatidylethanolamine, the major polar lipids were two unidentified aminophospholipids, one unidentified aminolipid and three unidentified polar lipids. The major cell-wall sugars were ribose, xylose and galactose. It is proposed that strain DCY13T represents a novel species in the genus Sediminibacterium , for which the name Sediminibacterium ginsengisoli sp. nov. is proposed. The type strain is DCY13T ( = KCTC 12833T  = JCM 15794T  = DSM 22335T). Emended descriptions of the genus Sediminibacterium and of Sediminibacterium salmoneum are also proposed.
