A Gram-stain-negative, motile, facultatively anaerobic rod-shaped bacterium with a polar flagellum, designated strain S7T was isolated from seawater sample collected at Uljin marina, in the East Sea of the Republic of Korea. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that strain S7T was affiliated with members of genus Ferrimonas, showing the highest sequence similarities to the type strains Ferrimonas senticii P2S11T (95.7 %), Ferrimonas balearica PATT (95.7 %) and Ferrimonas pelagia CBA4601T (95.1 %). The genome was 4.13 Mbp with a DNA G+C content of 49.4 %. The average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) between S7T and F. senticii P2S11T and F. balearica PATT yielded ANI values of 71.9 and 70.7 %, and dDDH values of 15.1 and 13.9 %, respectively. The genome of S7T was predicted to encode triacylglycerol lipase, phospholipase A1/A2 and lysophospholipase as well as esterase involved in lipolytic processes. Growth was observed at 8–31 °C (optimum 27 °C), at pH 7–9 (optimum pH 7), and with 1–6 % NaCl (optimum 2 %). The respiratory quinones were MK-7 and Q-7 and the major fatty acids (>10 %) were C16 : 0, C16 : 1ω9c, C17 : 1ω8c, and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The major polar lipids were identified as phosphatidylethanolamine, phosphatidylglycerol, two unidentified phospholipids, and three unidentified lipids. On the basis of the results of this polyphasic analysis, it was determined that the strain represents a novel species of the genus Ferrimonas , for which the name Ferrimonas lipolytica sp. nov. is proposed. The type strain is S7T (=KCTC 72490T=JCM 33793T).

Five beige bacterial strains (176/10T, 178/10, 182/10, 185/7 and 193/8) were isolated from white storks in Poland and found to share identical 16S rRNA gene sequences; they were also investigated in a polyphasic taxonomic study. The cells of all isolates were rod-shaped and Gram-stain-negative. A comparison of the 16S rRNA gene sequences of these organisms with the sequences of the type strains of the most closely related species of the genus Psychrobacter showed highest sequence similarities to the type strains of Psychrobacter pulmonis and Psychrobacter faecalis (both 97.1 %). The 16S rRNA gene sequence similarities to all other species of the genus Psychrobacter were below 96.3 %. All five isolates showed an identical profile of physiological reactions and almost identical fatty acid profiles consisting of mainly C18 : 1ω9c, but also C12 : 0 3-OH as a characteristic hydroxylated fatty acid. A quinone system with mainly ubiquinone Q-8 was detected and the polar lipid profile of the type strain, 176/10T, was mainly composed of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine and diphosphatidylglycerol, plus some hitherto uncharacterized phospholipids and one aminolipid. The major polyamines were spermidine and putrescine. DNA–DNA hybridizations between 176/10T and the type strains of P. pulmonis and P. faecialis resulted in relatedness values below 70 %. These results indicate that the strains represent a novel species, for which the name Psychrobacter ciconiae sp. nov. (type strain 176/10T = CIP 110777T = LMG 28175T = CCM 8519T) is proposed.

A Gram-stain-negative, aerobic, motile, short rod-shaped, catalase-negative and oxidase-positive bacterium, strain CAU 1568T, was isolated from marine sediment sand sampled at Sido Island in the Republic of Korea. The optimum conditions for growth were at 25–30 °C, at pH 6.5–8.5 and with 0–4.0 % (w/v) NaCl. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain CAU 1568T was a member of the genus Photobacterium with high similarity to Photobacterium salinisoli JCM 30852T (97.7 %), Photobacterium halotolerans KACC 17089T (97.3 %) and Photobacterium galatheae LMG F28894T (97.3 %). The predominant cellular fatty acids were C16 : 0, summed feature 3 (C16 : 1  ω6c and/or C16 : 1  ω7c) and summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c), with Q-8 as the major of isoprenoid quinone. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerols, phosphatidylcholine, phosphatidylethanolamine, phospholipid, two aminophospholipids and three unidentified lipids. The whole genome size of strain CAU 1568T was 4.8 Mb with 50.1 mol% G+C content; including 38 contigs and 4233 protein-coding genes. These taxonomic data support CAU 1568T as representing a novel Photobacterium species, for which the name Photobacterium arenosum sp. nov. is proposed. The type strain of this novel species is CAU 1568T (=KCTC 82404T=MCCC 1K05668T).

A Gram-stain-positive actinobacterial strain, designated ANK073T, was isolated from rhizosphere soil sampled at a spinach farming field in Shinan, Republic of Korea. Cells of strain ANK073T were found to be aerobic, non-motile, non-spore-forming rods which could grow at 20–40 °C (optimum, 30 °C), at pH 6.0–10.0 (optimum, pH 6.5–7.5) and at salinities of 0–4 % (w/v) NaCl (optimum, 0 % NaCl). The 16S rRNA gene sequence analysis showed that strain ANK073T belongs to the genus Agromyces with high sequence similarities to Agromyces humatus CD5T (98.8 %), Agromyces tardus SJ-23T (98.5 %) and Agromyces iriomotensis IY07-20T (98.4 %). The phylogenetic analysis indicated that strain ANK073T formed a distinct phyletic line in the genus Agromyces and the results of DNA–DNA relatedness and phylogenomic analysis based on whole genome sequences demonstrated that strain ANK073T could be separated from its closest relatives in the genus Agromyces . The strain contained 2,4-diaminobutylic acid, glycine, d-glutamic acid and d-alanine in the peptidoglycan. The predominant menaquinones were identified as MK-12 and MK-11, and the major fatty acids were anteiso-C17 : 0, anteiso-C15 :  0 and iso-C15:0. The major polar lipids were identified as diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The G+C content of the genome was determined to be 70.2 mol%. On the basis of its phenotypic and chemotaxonomic properties and the results of phylogenetic and phylogenomic analyses, strain ANK073T is considered to represent a novel species in the genus Agromyces , for which the name Agromyces humi sp. nov. is proposed. The type strain is ANK073T (=KACC 18683T=NBRC 111825T).

Two yellow-pigmented bacterial strains (100T and C26T), showing 98.4 % 16S rRNA gene sequence similarity to each other and isolated from a chicken in Germany and as a contaminant from an agar plate of a rhizosphere sample in Alabama, were studied by using a polyphasic taxonomic approach. Cells of both isolates were rod-shaped and stained Gram-negative. A comparison of the 16S rRNA gene sequences of the two organisms with the sequences of the type strains of the most closely related species of the genus Chryseobacterium showed the highest sequence similarities of strains 100T and C26T to the type strains of Chryseobacterium joostei (respectively 97.5 and 98.2 %), C. viscerum (96.6, 97.8 %), C. gleum (97.1, 97.7 %), C. arthrosphaerae (97.3%, 97.7 %), C. indologenes (97.2, 97.7 %), C. tructae (96.6, 97.6 %), C. jejuense (97.0, 97.6 %) and C. oncorhynchi (96.3, 97.5 %); 16S rRNA gene sequence similarities to members of all other species of the genus Chryseobacterium were below 97.5 %. The fatty acid profiles of both strains consisted of the major fatty acids iso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), iso-C17 : 1ω9c and iso-C17 : 0 3-OH, but also showed slight differences (absence or presence of C16 : 0 3-OH and iso-C15 : 1 F). DNA–DNA hybridizations between the two strains and between the novel strains and the type strains of C. joostei , C. indologenes , C. jejuense , C. tructae and C. viscerum resulted in relatedness values clearly below 70 %. These DNA–DNA hybridization results and the differentiating biochemical and chemotaxonomic properties showed that both strains 100T and C26T represent novel species, for which the names Chryseobacterium gallinarum sp. nov. (type strain 100T = LMG 27808T = CCM 8493T) and Chryseobacterium contaminans sp. nov. (type strain C26T = LMG 27810T = CCM 8492T) are proposed.

A novel filamentous bacterium, designated NariEXT, was isolated from soil collected from Chott Melghir salt lake, which is located in the south-east of Algeria. The strain was an aerobic, halotolerant, thermotolerant, Gram-positive bacterium that was able to grow in NaCl concentrations up to 21 % (w/v), at 37–60 °C and at pH 5.0–9.5. The major fatty acids were iso- and anteiso-C15 : 0. The DNA G+C content was 47.3 mol%. The major menaquinone was MK-7, but MK-6 and MK-8 were also present. The polar lipid profile consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylmonomethylethanolamine (methyl-PE). Results of molecular and phenotypic analysis led to the description of the strain as a new member of the family Thermoactinomycetaceae . The isolate was distinct from members of recognized genera of this family by morphological, biochemical and chemotaxonomic characteristics. Strain NariEXT showed 16S rRNA gene sequence similarities of 95.38 and 94.28 % with the type strains of Desmospora activa and Kroppenstedtia eburnea , respectively, but differed from both type strains in its sugars, polar lipids and in the presence of methyl-PE. On the basis of physiological and phylogenetic data, strain NariEXT represents a novel species of a new genus of the family Thermoactinomycetaceae for which the name Melghirimyces algeriensis gen. nov., sp. nov. is proposed. The type strain of Melghirimyces algeriensis, the type species of the genus, is NariEXT ( = DSM 45474T = CCUG 59620T).

A novel actinobacterium, strain BC637T, was isolated from a biodeteriogenic biofilm sample collected in 2009 in the Saint Callixstus Roman catacomb. The strain was found to belong to the genus Kribbella by analysis of the 16S rRNA gene. Phylogenetic analysis using the 16S rRNA gene and the gyrB, rpoB, relA, recA and atpD concatenated gene sequences showed that strain BC637T was most closely related to the type strains of Kribbella lupini and Kribbella endophytica . DNA–DNA hybridization experiments confirmed that strain BC637T is a genomic species that is distinct from its closest phylogenetic relatives, K. endophytica DSM 23718T (63 % DNA relatedness) and K. lupini LU14T (63 % DNA relatedness). Physiological comparisons showed that strain BC637T is phenotypically distinct from the type strains of K. endophytica and K. lupini . Thus, strain BC637T represents the type strain of a novel species, for which the name Kribella italica sp. nov. is proposed ( = DSM 28967T = NRRL B-59155T).

An actinobacterial strain designated MMS20-R1-14T was isolated from a riverside soil sample. Colonies on agar plates were orange to strong orange brown in colour, which later became black. The cells grew at 10–40 °C (optimum, 37 °C), pH 5.0–11.0 (pH 8.0) and in the presence of 0–4 % NaCl (1 %). The 16S rRNA gene sequence of strain MMS20-R1-14T showed highest similarities to Micromonospora wenchangensis CCTCC AA 2012002T (99.51 %) and Micromonospora rifamycinica AM105T (99.37 %). The orthoANI values between strain MMS20-R1-14T and the two type strains were 95.72 and 90.99 %, and the digital DNA–DNA hybridization values were 63.6 and 40.8 %, respectively, thus confirming the distinction of strain MMS20-R1-14T from its mostly related species. The DNA G+C content of strain MMS20-R1-14T was 72.9 mol%. The strain contained meso-diaminopimelic acid as the major cell-wall amino acid, and the characteristic whole-cell sugars were arabinose, xylose, glucose, ribose and rhamnose. The main cellular fatty acids were C18 : 1  ω9c, iso-C15 : 0 and iso-C16 : 0, the diagnostic polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine, and the predominant menaquinones were MK-10(H4) and MK-10(H6), all of which were consistent with those of Micromonospora . Strain MMS20-R1-14T showed antimicrobial activity against a range of bacterial and yeast species. The genome of the strain was found to contain 33 potential biosynthetic gene clusters for secondary metabolites, thus showing a high potential as a producer of bioactive compounds. On the basis of these phenotypic, genotypic and chemotaxonomic data, strain MMS20-R1-14T merits recognition as representing a novel species of the genus Micromonospora , for which the name Micromonospora humida sp. nov. (type strain=MMS20 R1-14T=KCTC 49541T=JCM 34494T) is proposed.

This paper presents a polyphasic taxonomic study of a Gram-stain-negative bacterium designated GA093T, a soil isolate capable of benzo(α)pyrene degradation. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain GA093T is a member of the genus Flavobacterium , and formed an independent phylogenetic line while clustering with the type strains of Flavobacterium hibernum , Flavobacterium branchiarum and Flavobacterium hydatis . Strain GA093T was facultatively anaerobic, and could grow at 4–33 °C (optimum, 30 °C), at pH 6–11 (optimum, pH 7) and in the presence of 0–2 % (w/v) NaCl (optimum, 0 %). Strain GA093T was capable of producing acid from various carbon sources, which was comparable to other related species of Flavobacterium . The strain contained MK-6 as the only isoprenoid quinone, iso-C15 : 0 as the major cellular fatty acid, phosphatidylethanolamine and phosphatidylinositol as diagnostic polar lipids, and sym-homospermidine as the major polyamine. The chemotaxonomic properties of strain GA093T were consistent with the general properties of Flavobacterium except the presence of phosphatidylinositol, which distinguished it from other related species. The total stretch of the obtained genome of GA093T was 5.05 Mbp, and the DNA G+C content was 34.79 mol%. The genome contained genes potentially related to the degradation of aromatic hydrocarbons. On the basis of the present polyphasic analysis, strain GA093T was found to have properties that distunguished it as representing a novel species of the genus Flavobacterium , for which the name Flavobacterium hydrocarbonoxydans sp. nov. is proposed. The type strain is GA093T (=KCTC 72594T=LMG 31760T).

A novel endophytic actinomycete, designated strain NEAU-TX2-2T, was isolated from moss and characterized using a polyphasic approach. The isolate was found to have morphological characteristics typical of the genus Microbispora . The isolate formed longitudinally paired spores on the tips of short sporophores that branched from aerial hyphae. Analysis of the 16S rRNA gene sequence supported the assignment of the novel strain to the genus Microbispora , and strain NEAU-TX2-2T exhibited 99.08 and 98.62 % gene sequence similarities to Microbispora amethystogenes JCM 3021T and Microbispora rosea subsp. rosea JCM 3006T, respectively. However two tree-making algorithms supported the position that strain NEAU-TX2-2T formed a distinct clade with M. rosea subsp. rosea JCM 3006T. A low level of DNA–DNA relatedness allowed the isolate to be differentiated from M. amethystogenes JCM 3021T and M. rosea subsp. rosea JCM 3006T. Moreover, strain NEAU-TX2-2T could also be distinguished from its closest phylogenetic relatives by morphological and physiological characteristics. Therefore, it is proposed that strain NEAU-TX2-2T represents a novel species of the genus Microbispora for which the name Microbispora bryophytorum sp. nov. is proposed. The type strain is NEAU-TX2-2T ( = CGMCC 4.7138T = DSM 46710T).
