Emended Description

A Gram-stain-negative, rod-shaped, non-motile and yellow-pigmented bacterial strain, designated strain JJ013T, was isolated from an artificial lake in Jeollabuk-do, South Korea, and characterized using a polyphasic approach. The 16S rRNA gene sequence of strain JJ013T indicated that the isolate belonged to the family Flavobacteriaceae and exhibited similarity levels of 96.6 % to the type strains of Flavobacterium cheonanense and Flavobacterium koreense and 96.5 % to the type strain of Flavobacterium chungnamense . Growth was observed at 20–30 °C and pH 5.0–7.0. The major cellular fatty acids of the novel strain were iso-C15 : 0 (27.5 %), iso-C15 : 1 G (17.8 %), iso-C17 : 0 3-OH (9.4 %) and iso-C15 : 0 3-OH (9.2 %). Flexirubin-type pigments were present. The DNA G+C content of strain JJ013T was 33.9 mol%, the major respiratory quinone was menaquinone-6 (MK-6) and the major polyamine was sym-homospermidine. The polar lipid profile of the strain JJ013T consisted of a phosphatidylethanolamine (PE), two unknown aminolipids (AL1–2), three unidentified lipid (L1–3) and an unknown glycolipid (GL). On the basis of the morphological and physiological properties and biochemical evidence presented, it is concluded that strain JJ013T represents a novel species of the genus Flavobacterium , for which the name Flavobacterium aciduliphilum sp. nov. is proposed; the type strain is JJ013T ( = KACC 16594T = JCM 18211T). Since C15 : 0, which is known as a predominant fatty acid of the genus Flavobacterium was not detected in the novel strain and other reference strains, we propose an emended description of the genus Flavobacterium .

The Gram-strain-negative, rod-shaped, facultatively anaerobic, non-motile bacterial strain, designated S1-10T, was isolated from marine sediment. Strain S1-10T grew at 4–42 °C (optimally at 30–35 °C), at pH 7.0–10 (optimally at pH 9) and in the presence of 0.5–8 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S1-10T was related to the genus Aequorivita and had highest 16S rRNA gene sequence similarity to Aequorivita viscosa 8-1bT (97.7%). The predominant cellular fatty acids were iso-C15 : 0 and anteiso-C15 : 0. The main respiratory quinone was menaquinone 6 (MK-6). The genomic DNA G+C content of strain S1-10T was 34.6 mol%. The polar lipid profile of strain S1-10T contained phosphatidylethanolamine, two aminolipids, two glycolipids, one phosphoglycolipid and three unidentified polar lipids. In addition, the maximum values of in silico DNA–DNA hybridization (isDDH) and average nucleotide identity (ANI) between strain S1-10T and A. viscosa CGMCC 1.11023T were 15.4 and 75.7 %, respectively. Combined data from phenotypic, phylogenetic, isDDH and ANI analyses demonstrated that strain S1-10T is the representative of a novel species of the genus Aequorivita , for which we propose the name Aequorivita sinensis sp. nov. (type strain S1-10T=CGMCC 1.12579T=JCM 19789T). We also propose that Vitellibacter todarodis and Vitellibacter aquimaris should be transferred into genus Aequorivita and be named Aequorivita todarodis comb. nov. and Aequorivita aquimaris comb. nov., respectively. The type strain of Aequorivita todarodis comb. nov. is MYP2-2T (= KCTC 62141T= NBRC 113025T) and the type strain of Aequorivita aquimaris comb. nov. is D-24T (=KCTC 42708T=DSM 101732T).

Two Gram-stain-negative, aerobic, non-motile bacterial strains, 36D10-4-7T and 30C10-4-7T, were isolated from bark canker tissue of Populus × euramericana, respectively. 16S rRNA gene sequence analysis revealed that strain 36D10-4-7T shows 98.0 % sequence similarity to Sphingomonas adhaesiva DSM 7418T, and strain 30C10-4-7T shows highest sequence similarity to Sphingobacterium arenae H-12T (95.6 %). Average nucleotide identity analysis indicates that strain 36D10-4-7T is a novel member different from recognized species in the genus Sphingomonas . The main fatty acids and respiratory quinone detected in strain 36D10-4-7T are C18 : 1  ω7c and/or C18 : 1  ω6c and Q-10, respectively. The polar lipids are diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, aminolipid, phosphatidylethanolamine, sphingoglycolipid, two uncharacterized phospholipids and two uncharacterized lipids. For strain 30C10-4-7T, the major fatty acids and menaquinone are iso-C15 : 0, C16 : 1  ω7c and/or C16 : 1  ω6c and iso-C17 : 0 3-OH and MK-7, respectively. The polar lipid profile includes phosphatidylethanolamine, phospholipids, two aminophospholipids and six unidentified lipids. Based on phenotypic and genotypic characteristics, these two strains represent two novel species within the genera Sphingomonas and Sphingobacterium . The name Sphingomonas corticis sp. nov. (type strain 36D10-4-7T=CFCC 13112T=KCTC 52799T) and Sphingobacterium corticibacterium sp. nov. (type strain 30C10-4-7T=CFCC 13069T=KCTC 52797T) are proposed.

A Gram-stain-negative, short rod-shaped, non-flagellated, yellow bacterium, designated strain 5GHs7-2T, was isolated from a greenhouse soil sample in South Korea. 16S rRNA gene sequence analysis of strain 5GHs7-2T indicated that the isolate belonged to the family Chitinophagaceae , and exhibited the highest sequence similarities with members of the genera Terrimonas (89.2–92.6 %), Sediminibacterium (90.8–91.4 %) and Chitinophaga (89.2–91.7 %), Filimonas lacunae YT21T (91.7 %), members of the genus Segetibacter (90.2–91.6 %), Parasegetibacter luojiensis RHYL-37T (90.9 %) and Flavihumibacter petaseus T41T (91.2 %). Flexirubin-type pigments were present. The major cellular fatty acids of the novel strain were iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1 G. The polar lipid profile consisted of a large amount of phosphatidylethanolamine, and moderate and small amounts of several unknown aminolipids and lipids. The only respiratory quinone of strain 5GHs7-2T was MK-7, and the DNA G+C content was 47.6 mol%. On the basis of the evidence presented, it is concluded that strain 5GHs7-2T represents a novel species of a new genus in the family Chitinophagaceae , for which the name Parafilimonas terrae gen. nov., sp. nov. is proposed. The type strain of the type species is 5GHs7-2T ( = KACC 17343T = DSM 28286T).

Reference Strains

In the present study we investigated the taxonomic status of 20 lactic acid bacteria (LAB) originating from packaged meat. On the basis of 16S rRNA gene sequence similarity, these strains were shown to belong to the genus Leuconostoc with Leuconostoc gelidum , Leuconostoc inhae and Leuconostoc gasicomitatum as the closest phylogenetic relatives. The novel strains shared more than 70 % DNA–DNA relatedness with type and reference strains of both L. gelidum and L. gasicomitatum . The DNA–DNA relatedness values between L. gelidum type and reference strains and L. gasicomitatum type and reference strains were also above 70 %, showing that all these strains belonged to the same species. Sequence analyses of concatenated atpA, pheS, and rpoA genes demonstrated that the novel strains as well as type and reference strains of L. gelidum and L. gasicomitatum are phylogenetically closely related, but form three clearly separated subgroups. Numerical analysis of HindIII ribopatterns and phenotypic tests supported this subdivision. Based on the data presented in this study, we propose to reclassify Leuconostoc gasicomitatum as Leuconostoc gelidum subsp. gasicomitatum comb. nov. (type strain, LMG 18811T = DSM 15947T). The novel strains isolated in the present study represent a novel subspecies, for which the name Leuconostoc gelidum subsp. aenigmaticum subsp. nov. is proposed, with POUF4dT ( = LMG 27840T = DSM 19375T) as the type strain. The proposal of these two novel subspecies automatically creates the subspecies Leuconostoc gelidum subsp. gelidum subsp. nov. (type strain, NCFB 2775T = DSM 5578T). An emended description of Leuconostoc gelidum is also provided.

A novel actinomycete, designated strain PT708T, was isolated from cave soil collected in Pha Tup Cave Forest Park, Nan province, Thailand. It produced compounds with antimicrobial and anticancer activities. Its chemotaxonomic properties were consistent with those of members of the genus Nonomuraea . The major menaquinone was MK-9(H4), with minor amounts of MK-9(H6), MK-9(H2), MK-10(H2) and MK-8(H4). The polar lipid profile contained phosphatidylmonomethylethanolamine, diphosphatidylglycerol, hydroxy-phosphatidylmonomethylethanolamine, hydroxy-phosphatidylethanolamine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol mannoside and phosphatidylinositol. The major fatty acids were iso-C16 : 0, 10-methyl C17 : 0, C16 : 0 and C17 : 1ω6c. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain PT708T belonged to the genus Nonomuraea and was most closely related to Nonomuraea rhizophila YIM 67092T (98.50 % sequence similarity) and Nonomuraea rosea GW 12687T (98.30 %). The genomic DNA G+C content of strain PT708T was 73.3 mol%. Unlike the recognized members of the genus Nonomuraea , the novel strain formed single spores at the tips of aerial hyphae. Based on the phenotypic, phylogenetic and genotypic evidence, strain PT708T represents a novel species of the genus Nonomuraea , for which the name Nonomuraea monospora sp. nov. is proposed. The type strain is PT708T ( = TISTR 1910T = JCM 16114T).

A bacterial strain, isolated from a sample of reef-building coral (Isopora palifera) collected off the coast of southern Taiwan, was characterized using a polyphasic taxonomic approach. The strain, designated sw-2T, was Gram-staining-negative, aerobic, rod-shaped and motile, with subpolar flagella, and formed greyish pink colonies. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain sw-2T was most closely related to Roseivivax halodurans Och 239T (97.4 % sequence similarity) and Roseivivax halotolerans Och 210T (96.4 %). The novel strain did not require NaCl for growth and exhibited optimal growth at 35–40 °C, at pH 7.5–8.0 and with 3–7 % (w/v) NaCl. It produced bacteriochlorophyll a under aerobic conditions. Summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c; 63.7 %) predominated in the cellular fatty acid profile. The novel strain’s major respiratory quinone was ubiquinone Q-10 and its genomic DNA G+C content was 68.8 mol%. The polar lipid profile consisted of a mixture of phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, diphosphatidylglycerol, phosphatidyldimethylethanolamine, sulfo-quinovosyl diacylglycerol and three uncharacterized phospholipids. The level of DNA–DNA relatedness between strain sw-2T and Roseivivax halodurans Och 239T was only 15.0 %. The results of physiological and biochemical tests allowed the clear phenotypic differentiation of the novel strain from all established species of the genus Roseivivax . Based on the genotypic, phenotypic and chemotaxonomic data, strain sw-2T represents a novel species in the genus Roseivivax , for which the name Roseivivax isoporae sp. nov. is proposed. The type strain is sw-2T ( = LMG 25204T = BCRC 17966T).

A Gram-staining-negative, aerobic, rod-shaped bacterium, designated strain T202T, was isolated from the gill of a cultured flounder (Paralichthys olivaceus). Based on 16S rRNA gene sequence similarity, strain T202T was a member of the family Colwelliaceae and shared 93.32–96.58 % similarity with type strains of all members of the most closely related genus Thalassomonas . Phylogenetically, the isolate shared a root with the type strains of four marine species, Thalassomonas agariperforans M-M1T, Thalassomonas agarivorans TMA1T, Thalassomonas loyana CBMAI 722T and Thalassomonas ganghwensis JC2041T. Optimal growth occurred in the presence of 2–4 % (w/v) NaCl, at pH 7.0–8.0 and at 28 °C. Ubiquinone 8 (Q-8) was the predominant respiratory quinone. The major fatty acids were C16 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C16 : 1ω9c and C17 : 1ω8c. The major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The DNA G+C content of strain T202T was 37 mol%. On the basis of polyphasic analysis, especially the phylogenetic relationships and the lower DNA G+C content, strain T202T is considered to represent a novel species in a new genus, for which the name Thalassotalea piscium gen. nov., sp. nov. is proposed. The type strain of Thalassotalea piscium is T202T ( = JCM 18590T = DSM 26287T = KCTC 32144T). Because Thalassomonas agariperforans M-M1T, Thalassomonas agarivorans TMA1T, Thalassomonas loyana CBMAI 722T and Thalassomonas ganghwensis JC2041T formed a phylogenetic group together with strain T202T that was clearly separated from other known strains of Thalassomonas , these four species are reclassified as members of the genus Thalassotalea as Thalassotalea agariperforans comb. nov. (type strain M-M1T = KCTC 23343T = CCUG 60020T), Thalassotalea agarivorans comb. nov. (type strain TMA1T = BCRC 17492T = JCM 13379T = DSM 19706T), Thalassotalea loyana comb. nov. (type strain CBMAI 722T = LMG 22536T) and Thalassotalea ganghwensis comb. nov. (type strain JC2041T = IMSNU 14005T = KCTC 12041T = DSM 15355T). The type species of the genus Thalassotalea is Thalassotalea ganghwensis gen. nov., comb. nov. An emended description of the genus Thalassomonas is also proposed.

A novel Gram-stain-negative, aerobic, rod-shaped strain designated PG04T was isolated from the rhizosphere of watermelon plants cultivated in Beijing, China. A polyphasic taxonomic study was performed on the new isolate. On the basis of 16S rRNA gene sequence similarity studies, isolate PG04T belonged clearly to the genus Hansschlegelia and was most closely related to Hansschlegelia zhihuaiae (97.3 % similarity to the type strain). The predominant respiratory quinone was ubiquinone 10 (Q-10) and the polar lipid profile was composed of the major lipids diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine. The major fatty acids were C18 : 1ω7c (41.3 %), C19 : 0 cyclo ω8c (30.6 %) and C16 : 0 (19.1 %). The G+C content of the DNA was about 64.4 mol%. DNA–DNA hybridization experiments showed 34.4 % relatedness between strain PG04T and H. zhihuaiae DSM 18984T. The results of physiological and biochemical tests and differences in fatty acid profiles allowed clear phenotypic differentiation of strain PG04T from the most closely related species in the genus, H. zhihuaiae . Strain PG04T therefore represents a novel species within the genus Hansschlegelia , for which the name Hansschlegelia beijingensis sp. nov. is proposed, with the type strain PG04T ( = DSM 25481T = ACCC 05759T).

We carried out a polyphasic taxonomic study on a new halophilic strain designated 3(2)T, isolated from Meighan wetland, Iran. Cells of the novel strain were Gram-stain-negative, non-hemolytic, catalase- and oxidase-positive, rod-shaped, non-endospore-forming and motile. Cell growth occurred at 3–15 % NaCl (w/v; optimum, 5 %), pH 7.0–9.0 (optimum, pH 7.5–8.0) and 15–35 °C (optimum, 30 °C). 16S rRNA gene sequence comparisons confirmed the affiliation of strain 3(2)T to the class Gammaproteobacteria and the genus Halomonas with highest similarity to Halomonas daqiaonensis YCSA28T (98.4 %) and Halomonas ventosae Al12T (97.9 %). Experimental and in silico DNA–DNA hybridization values were 42.7 and 35.1% with H. daqiaonensis IBRC-M 10931T and 48 and 35.2% with H. ventosae IBRC-M 10566T, respectively, and indicated that they are different members of the same genus. The genome of the type strain was characterized by a size of 3.83 Mbp with 63 scaffolds and a G+C content of 64.8 mol%. Moreover, the average nucleotide identity values against H. ventosae Al12T and H. daqiaonensis YCSA28T were 88.8 and 88.5 %, respectively. The predominant respiratory quinone was Q-9 (92 %) with Q-8 (8 %) as a minor component. Major fatty acids were C16 : 0 cyclo, C19 : 0 ω8c, C16 : 1 ω7c and/or iso-C15:0 2-OH, C12 : 0 3-OH and C18 : 1 ω7c. The polar lipid profile of the strain contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphoaminoglycolipid and four unidentified phospholipids. According to our results, strain 3(2)T could be classified as a novel species in the genus Halomonas for which the name Halomonas lysinitropha sp. nov. is proposed. The type strain is 3(2)T (=IBRC M 10929T=LMG 29450T=CIP 111708T).

A bacterial strain designated 26BT, which had been isolated from the cloaca of a toad-headed turtle, was subjected to a comprehensive taxonomic study. Comparison of 16S rRNA gene sequences demonstrated that strain 26BT is a member of the family Neisseriaceae . Based on highest similarity values, Neisseria animaloris DSM 21642T (95.15 %), Alysiella filiformis ATCC 15532T (95.06 %), Uruburuella testudinis 07_OD624T (94.71 %), Uruburuella suis CCUG 47806T (94.66 %) and Alysiella crassa DSM 2578T (94.64 %) were identified as the closest relatives. Average nucleotide identity values based on the blast algorithm (ANIb) indicated that U. suis (76.10/76.17 %), Neisseria shayeganii 871T (74.34/74.51 %), Stenoxybacter acetivorans (73.30/73.41 %), N. animaloris (72.98/72.80) %, A. filiformis (71.14/71.21 %) and A. crassa (70.53/71.15 %) are the next closest relatives. Like ANIb, genome-based phylogeny did not suggest the affiliation of strain 26BT with any established genus. The polyamine pattern consisted of the major compounds putrescine, 1,3-diaminopropane and spermidine and the major quinone was ubiquinone Q-8. In the polar lipid profile, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and an ornithine lipid were predominant. The fatty acid profile contained predominantly C16 : 1 ω7c, C12 : 0, C14 : 0, C16 : 0 and C12 : 0 3OH. The size of the genome was 2.91 Mbp and the genomic G+C content was 54.0 mol%. Since these data do not demonstrate an unambiguous association with any established genus, we here propose the novel genus Paralysiella with the type species Paralysiella testudinis gen. nov., sp. nov. The type strain is 26BT (=CCM 9137T=LMG 32212T).
