A bacterial strain designated TNR-2T was isolated from spring water in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain TNR-2T were aerobic, Gram-stain-negative, straight rods, motile by a single polar flagellum and containing poly-β-hydroxybutyrate. The cells were covered by large capsules and formed yellow colonies. Growth occurred at 15–37 °C (optimum, 20–30 °C), with 0–1.0 % NaCl (optimum, 0–0.1 %) and at pH 5.0–8.0 (optimum, pH 6.0). According to a phylogenetic tree based on 16S rRNA gene sequence analysis, strain TNR-2T belonged to the genus Sphingomonas and clustered with Sphingomonas alpina S8-3T, with which it shared the highest 16S rRNA gene sequence similarity (95.6 %). The major fatty acids (>10 %) of strain TNR-2T were C18 : 1ω7c, C17 : 1ω6c and C16 : 0. The DNA G+C content was 62.8 mol%. The major isoprenoid quinone was Q-10. The major polyamine was homospermidine. The polar lipid profile consisted of sphingoglycolipid, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylcholine, diphosphatidylglycerol, two uncharacterized glycolipids and an uncharacterized phospholipid. Phenotypic characteristics of the novel strain differed from those of the closest related species of the genus Sphingomonas. On the basis of the genotypic, chemotaxonomic and phenotypic data, strain TNR-2T represents a novel species in the genus Sphingomonas, for which the name Sphingomonas fonticola sp. nov. is proposed. The type strain is TNR-2T ( = BCRC 80539T = LMG 27384T = KCTC 32258T).

AbstractStrain M2T was isolated from the beach of Cuxhaven, Wadden Sea, Germany, in course of a program to attain new producers of bioactive natural products. Strain M2T produces litoralimycin and sulfomycin-type thiopeptides. Bioinformatic analysis revealed a potential biosynthetic gene cluster encoding for the M2T thiopeptides. The strain is Gram-stain-positive, rod shaped, non-motile, spore forming, showing a yellow colony color and forms extensively branched substrate mycelium and aerial hyphae. Inferred from the 16S rRNA gene phylogeny strain M2T affiliates with the genus Streptomonospora. It shows 96.6% 16S rRNA gene sequence similarity to the type species Streptomonospora salina DSM 44593 T and forms a distinct branch with Streptomonospora sediminis DSM 45723 T with 97.0% 16S rRNA gene sequence similarity. Genome-based phylogenetic analysis revealed that M2T is closely related to Streptomonospora alba YIM 90003 T with a digital DNA-DNA hybridisation (dDDH) value of 26.6%. The predominant menaquinones of M2T are MK-10(H6), MK-10(H8), and MK-11(H6) (> 10%). Major cellular fatty acids are iso-C16:0, anteiso C17:0 and C18:0 10-methyl. The polar lipid profile consisted of diphosphatidylglycerol phosphatidyl glycerol, phosphatidylinositol, phosphatidylcholine, phosphatidylethanolamine, three glycolipids, two unknown phospholipids, and two unknown lipids. The genome size of type strain M2T is 5,878,427 bp with 72.1 mol % G + C content. Based on the results obtained from phylogenetic and chemotaxonomic studies, strain M2T (= DSM 106425 T = NCCB 100650 T) is considered to represent a novel species within the genus Streptomonospora for which the name Streptomonospora litoralis sp. nov. is proposed.

A novel Gram-stain-positive, aerobic, motile, non-spore-forming coccus-shaped actinomycete, designated strain YIM 121300T, was isolated from alkaline sediment in Yuanjiang, Yunnan province, south-west China. Phylogenetic analyses based on the 16S rRNA gene sequence showed that strain YIM 121300T was affiliated to the genus Kineococcus, and was closely related to Kineococcus aurantiacus IFO 15268T (97.3 % similarity). 16S rRNA gene sequence similarity to other species of the genus Kineococcus was < 97 %. The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid. The whole-cell sugars contained arabinose, galactose, glucose, mannose and ribose. The predominant menaquinone was MK-9(H2). Mycolic acids were not detected. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and an unknown phospholipid. The predominant fatty acids were anteiso-C15 : 0 and anteiso-C15 : 1 A. The G+C content of the genomic DNA was 75.1 mol%. DNA–DNA relatedness (55 ± 4 % to K. aurantiacus IFO 15268T) and differential phenotypic data demonstrated that strain YIM 121300T was distinguished from all related species of the genus Kineococcus. On the basis of data from the present polyphasic study, the organism should be assigned to a novel species of the genus Kineococcus, for which the name Kineococcus gypseus sp. nov. is proposed. The type strain is YIM 121300T ( = CCTCC AA 2013232T = DSM 27627T).

A Gram-staining-positive, spore-forming, strictly anaerobic bacterium, designated strain LAM0A37T, was isolated from enrichment samples collected from a petroleum reservoir in Shengli oilfield. Cells of strain LAM0A37T were rod-shaped and motile by peritrichous flagella. The optimal temperature and pH for growth were 40 °C and 7.0–7.5, respectively. The strain did not require NaCl for growth but tolerated up to 3 % (w/v) NaCl. Strain LAM0A37T was able to utilize glucose, fructose, maltose, xylose, sorbitol, cellobiose, melibiose and melezitose as sole carbon sources. Sulfite was used as an electron acceptor. The main products of glucose fermentation were acetate and CO2. The predominant fatty acid was C16 : 0 (23.6 %). The main polar lipid profile comprised of five glycolipids, six phospholipids and two lipids. No menaquinone was detected. The genomic DNA G+C content was 27.1 ± 0.2 mol% as determined by the T m method. Analysis of the 16S rRNA gene sequence indicated that the isolate was a member of the genus Terrisporobacter, and was most closely related to Terrisporobacter glycolicus JCM 1401T and Terrisporobacter mayombei DSM 6539T with 98.3 % 16S rRNA gene sequence similarity to both. DNA–DNA hybridization values between strain LAM0A37T and type strains of Terrisporobacter glycolicus and Terrisporobacter mayombei were 45.6 ± 0.3 % and 38.3 ± 0.4 %, respectively. Based on phenotypic, phylogenetic and chemotaxonomic characteristics, strain LAM0A37T is suggested to represent a novel species of the genus Terrisporobacter, for which the name Terrisporobacter petrolearius sp. nov. is proposed. The type strain is LAM0A37T ( = ACCC 00740T = JCM 19845T).

Phenotypic Data

We analysed the taxonomic position of the genus Listonella based on phylogenetic, genomic and phenotypic data. The species of the genus Listonella were nested within the genus Vibrio according to the 16S rRNA gene sequence-based phylogenetic tree. The closest neighbour of Vibrio (Listonella) anguillarum strains LMG 4437T and ATCC 68554 ( = strain 775) was Vibrio ordalii LMG 13544T, with more than 99.5 % 16S rRNA gene sequence similarity. Furthermore, Vibrio (Listonella) pelagius is highly related to Vibrio splendidus. According to average amino acid identity (AAI), multilocus sequence analysis (MLSA) and Karlin genome signature, the closest neighbour of L. anguillarum ATCC 68554 is V. ordalii LMG 13544T, with 95 % AAI, 98 % MLSA and 5 in Karlin. V. anguillarum ATCC 68554 and Vibrio cholerae N16961 had 77 % similarity in AAI, 85 % in MLSA and 14 in the Karlin signature. Phenotypic analyses of previously published data for V. (L.) anguillarum and V. (L.) pelagius revealed that the genus Listonella is extremely similar to the genus Vibrio. V. ordalii and L. anguillarum strains yielded up to 67 % DNA–DNA hybridization. There are only a few phenotypic features that might be used to discriminate these two species: L. anguillarum is positive for the Voges–Proskauer reaction, citrate utilization, starch hydrolysis, lipase activity and acid production from glycerol, sorbitol and trehalose, whereas V. ordalii is negative for these traits. We suggest that the genus Listonella is a later heterotypic synonym of the genus Vibrio and propose to use the names Vibrio anguillarum and Vibrio pelagius in place of Listonella anguillarum and Listonella pelagia, respectively.

Lactobacillus ferintoshensis has recently been described as a novel species, distinct from its close phylogenetic neighbours Lactobacillus buchneri, Lactobacillus kefiri and Lactobacillus hilgardii. Two highly related species with validly published names, Lactobacillus parakefiri and Lactobacillus parabuchneri, were not considered in the study due to the lack of 16S rRNA gene sequence data at that time. Since the publication of the study, the sequences have become available and have revealed that L. ferintoshensis and L. parabuchneri share 99·7 % 16S rRNA gene sequence similarity. Further genomic and phenotypic data, derived from fluorescent amplified fragment length polymorphism, DNA–DNA hybridization and API 50 CHL analyses, have demonstrated that the species are synonymous.

Gene Sequence Analysis

A Gram-negative, non-spore-forming, rod-shaped bacterial strain, RL-2T, was isolated from seawater of the East Sea in Korea and was subjected to a polyphasic taxonomic study. Strain RL-2T grew optimally at pH 7.5–8.0, at 20 °C and in the absence of NaCl. Phylogenetic trees based on 16S rRNA gene sequence analysis showed that strain RL-2T forms a cluster with Perlucidibaca piscinae IMCC1704T and various uncultured and unidentified gammaproteobacteria. Strain RL-2T exhibited 16S rRNA gene sequence similarity values of 96.1 % to Perlucidibaca piscinae IMCC1704T and 93.7–99.7 % to the uncultured bacterial clones belonging to the cluster and an unidentified gammaproteobacterium. The fatty acid profile of strain RL-2T was similar to that of Perlucidibaca piscinae IMCC1704T, but the predominant ubiquinone type (Q-11) of strain RL-2T was different from that (Q-8) of Perlucidibaca piscinae IMCC1704T. The DNA G+C content of strain RL-2T was 61.3 mol%. On the basis of phylogenetic, chemotaxonomic and phenotypic data, strain RL-2T is considered to represent a novel species of a new genus in the family Moraxellaceae, for which the name Paraperlucidibaca baekdonensis gen. nov., sp. nov. is proposed. The type strain of Paraperlucidibaca baekdonensis is RL-2T ( = KCTC 23145T  = CCUG 59307T).

A novel actinomycete that was capable of degrading poly(l-lactic acid), strain CMU-PLA07T, was isolated from soil in northern Thailand. Strain CMU-PLA07T had biochemical, chemotaxonomic, morphological and physiological properties that were consistent with its classification in the genus Amycolatopsis. 16S rRNA gene sequence analysis showed that the isolate formed a phyletic line within the genus Amycolatopsis. Strain CMU-PLA07T was most similar to Amycolatopsis coloradensis IMSNU 22096T (99.5 % 16S rRNA gene sequence similarity) and Amycolatopsis alba DSM 44262T (99.4 %). However, strain CMU-PLA07T was distinguishable from the type strains of species of the genus Amycolatopsis on the basis of DNA–DNA relatedness and phenotypic data. Therefore, strain CMU-PLA07T is considered to represent a novel species of the genus Amycolatopsis, for which the name Amycolatopsis thailandensis sp. nov. is proposed. The type strain is CMU-PLA07T ( = JCM 16380T = BCC 38279T).
