A Gram-reaction-negative, yellow-pigmented, non-spore-forming rod, aerobic, motile bacterium, designated SJY3T, was isolated from soil samples collected from a Pu-erh tea cellar in Bolian Pu-erh tea estate Co. Ltd. in Pu'er city, Yunnan, south-west China. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate belonged to the genus Massilia . The closest phylogenetic relative was Massilia arenae CICC 24458T (99.5 %), followed by M. timonae CCUG45783T (97.9 %), M. oculi CCUG43427AT (97.8 %), and M. aurea DSM 18055T (97.8 %). The major fatty acids were C16 : 0 and C16 : 1  ω7c and/or C16 : 1  ω6c. The major respiratory quinone was ubiquinone Q-8 and the major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine. Genome sequencing revealed a genome size of 5.97 M bp and a G+C content of 65.4 mol%. Pairwise determined whole genome average nucleotide identity (gANI) values and digital DNA–DNA hybridization (dDDH) values were all below the threshold. Although the 16S rRNA gene similarity of stain SJY3T and Massilia arenae CICC 24458T was more than 99 %, the gANI, dDDH values and genomic tree clearly indicated that they were not of the same species. In summary, strain SJY3T represents a new species, for which we propose the name Massilia puerhi sp. nov. with the type strain SJY3T (=CGMCC 1.17158T=KCTC 82193T).

A Gram-negative, strictly aerobic, yellow-pigmented rod, designated DK69T, was isolated from soil collected from the waste liquid treatment facility of Bafeng Pharmaceutical Company in the city of Enshi, Hubei Province, China. Phylogenetic analysis based on 16S rRNA gene sequences placed strain DK69T in the genus Flavobacterium of the family Flavobacteriaceae . The highest 16S rRNA gene sequence similarities were found with Flavobacterium cauense R2A-7T (96.9 %), Flavobacterium saliperosum AS 1.3801T (96.3 %) and Flavobacterium suncheonense GH29-5T (95.7 %). The major fatty acids (≥5 %) were iso-C15 : 0, iso-C17 : 1ω9c, C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 0 3-OH. The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid. The major respiratory quinone was menaquinone-6. The genomic DNA G+C content was 34.4 mol%. Strain DK69T represents a novel species of the genus Flavobacterium , for which the name Flavobacterium enshiense sp. nov. is proposed. The type strain is DK69T ( = CCTCC AB 2011144T  = KCTC 23775T). Emended descriptions of the genus Flavobacterium and Flavobacterium cauense , Flavobacterium saliperosum and Flavobacterium suncheonense are also proposed.

A Gram-stain-negative, non-spore-forming, aerobic, motile, curved rod-shaped bacterium, designed strain R148T was isolated from a coralline algae Tricleocarpa sp. collected from Weizhou island, PR China. The optimal growth of R148T occurred at 25 °C, pH 8–9 in the presence of 0.5 % (w/v) NaCl on the basis of amended marine broth 2216. The genomic DNA G+C content was 59.5 mol%. The only detected respiratory quinone was Q-10. The major polar lipids were phosphatidylmethylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, and three unidentified ninhydrin-positive lipids. The major cellular fatty acids were C18 : 1ω7c, C16 : 1ω7c, C19 : 0cyclo 9, 10 DMA and C18 : 0. The results of 16S rRNA gene-based global alignment indicated that the closest neighbour of strain R148T was Pelagibius litoralis DSM 21314T (93.1 % similarity), the second is Limibacillus halophilus KCTC 42420T (92.2 %). The results of phylogenetic analysis indicated that R148T forms a distinct branch in the robust clade of R148T and P. litoralis DSM 21314T, while the taxonomic position of this clade in the family Rhodospirillaceae is ambiguous among phylogenetic approaches. The low 16S rRNA gene similarity and distinct polar lipid and cellular fatty acid profile could readily distinguish R148T from closely related type strains. So R148T is suggested to represent a novel species in a novel genus, for which the name Denitrobaculum tricleocarpae gen. nov., sp. nov. is proposed. The type strain is R148T (=MCCC 1K03781T=KCTC 72137T).

Two Gram-stain-negative, yellow-pigmented and strictly aerobic bacteria, designated strains SE-s27T and SE-s28T, were isolated from forest soil. Both strains were non-motile rods that were catalase-positive and oxidase-negative and grew optimally at 25–30 °C, pH 8.0 and with 0 % (w/v) NaCl. Strain SE-s28T produced flexirubin-type pigments, but strain SE-s27T did not produce them. Both strains contained menaquinone-6 as the sole respiratory quinone and phosphatidylethanolamine as a major polar lipid. As the major cellular fatty acids (>10 %), SE-s27T contained iso-C15 : 1 and iso-C15 : 1G, whereas SE-s28T contained iso-C15 : 0 and summed feature 3 comprising C16 : 1ω7c and/or C16 : 1ω6c and/or iso-C15 : 0 2-OH. The DNA G+C contents of strains SE-s27T and SE-s28T were 33.1 and 44.3 mol%, respectively. The results of phylogenetic analysis based on 16S rRNA gene sequences revealed that SE-s27T and SE-s28T formed respective distinct phylogenetic lineages within the genus Flavobacterium . Strains SE-s27T and SE-s28T were most closely related to Flavobacterium macrobrachii an-8T and Flavobacterium piscinae ICH-30T with 98.0 and 94.5 % 16S rRNA gene sequence similarities, respectively. In conclusion, strains SE-s27T and SE-s28T represent novel species of the genus Flavobacterium , for which the names Flavobacterium solisilvae sp. nov. and Flavobacterium silvaticum sp. nov. are proposed. The type strains of F. solisilvae and F. silvaticum are SE-s27T (=KACC 18802T=JCM 31544T) and SE-s28T (=KACC 18803T=JCM 31545T), respectively.

Novel aerobic, restricted facultatively methylotrophic bacteria were isolated from buds of English oak (Quercus robur L.; strain DubT) and northern red oak (Quercus rubra L.; strain KrD). The isolates were Gram-negative, asporogenous, motile short rods that multiplied by binary fisson. They utilized methanol, methylamine and a few polycarbon compounds as carbon and energy sources. Optimal growth occurred at 25 °C and pH 7.5. The dominant phospholipids were phosphatidylethanolamine, phosphatidylcholine, diphosphatidylglycerol and phoshatidylglycerol. The major cellular fatty acids of cells were C18 : 1 ω7c, 11-methyl C18 : 1 ω7c and C16 : 0. The major ubiquinone was Q-10. Analysis of 16S rRNA gene sequences showed that the strains were closely related to the members of the genus Hansschlegelia : Hansschlegelia zhihuaiae S113T(97.5–98.0 %), Hansschlegelia plantiphila S1T (97.4–97.6 %) and Hansschlegelia beijingensis PG04T(97.0–97.2 %). The 16S rRNA gene sequence similarity between strains DubT and KrD was 99.7 %, and the DNA–DNA hybridization (DDH) result between the strains was 85 %. The ANI and the DDH values between strain DubT and H. zhihuaiae S113T were 80.1 and 21.5  %, respectively. Genome sequencing of the strain DubT revealed a genome size of 3.57 Mbp and a G+C content of 67.0 mol%. Based on the results of the phenotypic, chemotaxonomic and genotypic analyses, it is proposed that the isolates be assigned to the genus Hansschlegelia as Hansschlegelia quercus sp. nov. with the type strain DubT (=VKM B-3284T=CCUG 73648T=JCM 33463T).

Hirudo Verbana

A Gram-staining-negative, non-endospore-forming, yellow-pigmented strain (E89T) was isolated from the skin of the medical leech Hirudo verbana obtained from a leech farm located in Biebertal, Germany. 16S rRNA gene sequencing analysis showed that the isolate was grouped in the genus Flavobacterium . Strain E89T was most closely related to Flavobacterium chilense LM-09-FpT (98.2 %), Flavobacterium chungangense CJ7T (98.1 %), and Flavobacterium oncorhynchi 631-08T (98.1 %). 16S rRNA gene sequence similarities to all other species of the genus Flavobacterium were ≤97.4 %. A menaquinone of the type MK-6 was found to be the predominant respiratory quinone and the polar lipid profile consisted of the major compounds phosphatidylethanolamine, phosphatidylserine, two unidentified aminolipids, one unknown phospholipid and two unknown lipids. The fatty acid profile was composed of iso-C15 : 0, C15 : 0, summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) found in major amounts and several hydroxylated fatty acids in smaller amounts, among them iso-C15 : 0 3-OH and iso-C17 : 0 3-OH. All these data support the allocation of the isolate in the genus Flavobacterium . Physiological/biochemical characterization and DNA–DNA hybridizations with the type strains of the most closely related species allowed a clear phenotypic and genotypic differentiation of the strain. Based on these data, strain E89T represents a novel species of the genus Flavobacterium , for which the name Flavobacterium cutihirudinis sp. nov. is proposed. The type strain is E89T ( = DSM 25795T = LMG 26922T = CIP 110374T).

A strictly anaerobic, Gram-stain-negative, non-spore-forming, non-motile, non-pigmented bacterium, strain J115T, was isolated from human faeces. Cells of strain J115T were straight rods, generally 1.8–3.0 µm, but could be up to 18 µm long. Growth occurred below 2 % (w/v) NaCl and 2 % (v/v) bile. Strain J115T produced acid from myo-inositol but not from d-glucose, d-ribose or d-xylose. Butyric acid was the major end-product from myo-inositol. The genomic DNA G+C content was 58.92 mol%. Phylogenetic analysis based on 16S rRNA gene sequencing indicated that the closest cultivated neighbours of strain J115T were Oscillibacter ruminantium GH1T (95.4 % similarity) and Oscillibacter valericigenes Sjm18-20T (94.1 %). Strain J115T was also related to the not-yet-cultured bacterium Oscillospira guilliermondii (92–93 % similarity). Coherently with the 16S rRNA gene sequence results, the ANI scores don't have units of strain J115T to O. ruminantium GH1T and O. valericigenes Sjm18-20T were 73.37 and 73.24, respectively, while in silico estimations of DNA–DNA hybridization were both 20.4 %, with confidence intervals of 18.2–22.9 % and 18.2–22.8 %, respectively. The major fatty acids were iso-C15 : 0 (24.2 %), C18 : 0 DMA (18.4 %), anteiso-C15 : 0 (15.2 %) and C16 : 0 DMA (7.6 %). No respiratory quinone was detected. Based on phenotypic features and phylogenetic position, it is proposed that this isolate represents a novel species in a new genus, Dysosmobacter welbionis gen. nov., sp. nov. The type strain of Dysosmobacter welbionis is J115T (DSM 106889T=LMG 30601T).

A novel bacterium, designated strain F051-1T, isolated from a seawater sample collected from the coast at Damupo beach in Pohang, Korea, was investigated in a polyphasic taxonomic study. Cells were yellow-pigmented, strictly aerobic, Gram-staining-negative and rod-shaped. The temperature, pH and NaCl ranges for growth were 4–30 °C, pH 6.0–9.0 and 1.0–6.0 % (w/v), respectively. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain F051-1T belongs to the genus Psychroserpens in the family Flavobacteriaceae . Its closest relatives were Psychroserpens burtonensis ACAM 188T (96.8 % 16S rRNA gene sequence similarity) and Psychroserpens mesophilus KOPRI 13649T (95.7 %). The major cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G and anteiso-C15 : 0. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, two unidentified aminolipids, one unidentified phospholipid and eight unidentified lipids. The major respiratory quinone was menaquinone-6 and the genomic DNA G+C content of the strain was 33.5 mol%. On the basis of phenotypic, phylogenetic and genotypic data, strain F051-1T represents a novel species within the genus Psychroserpens , for which the name Psychroserpens damuponensis sp. nov. is proposed. The type strain is F051-1T ( = KCTC 23539T  = JCM 17632T).

Pink-pigmented, facultatively methylotrophic bacteria, strains 87eT and 99bT, were isolated from the bryophytes Haplocladium microphyllum and Brachythecium plumosum, respectively. The cells of both strains were Gram-reaction-negative, motile, non-spore-forming rods. On the basis of 16S rRNA gene sequence similarity, strains 87eT and 99bT were found to be related to Methylobacterium organophilum ATCC 27886T (97.1 % and 97.7 %, respectively). Strains 87eT and 99bT showed highest 16S rRNA gene similarity to Methylobacterium gnaphalii 23eT (98.3 and 99.0 %, respectively). The phylogenetic similarities to all other species of the genus Methylobacterium with validly published names were less than 97 %. Major cellular fatty acids of both strains were C18 : 1ω7c and C18 : 0. The results of DNA–DNA hybridization, phylogenetic analyses based on 16S rRNA and cpn60 gene sequences, fatty acid profiles, whole-cell matrix-assisted, laser-desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) analysis, and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strains 87eT and 99bT from their phylogenetically closest relatives. We propose that strains 87eT and 99bT represent novel species within the genus Methylobacterium , for which the names Methylobacterium haplocladii sp. nov. (type strain 87eT = DSM 24195T = NBRC 107714T) and Methylobacterium brachythecii sp. nov. (type strain 99bT = DSM 24105T = NBRC 107710T) are proposed.
