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.

Phenotypic Data

An actinomycete strain, designated IR27-S3T, was isolated from a forest soil sample collected from Iriomote Island, Okinawa, Japan. Cells of the isolate were Gram-stain-positive, aerobic, non-sporulating, non-motile coccoids or short rods. The strain grew in the presence of 0–7 % (w/v) NaCl, at pH 6–8 and at 12–37 °C, with optimum growth at 30 °C. Chemotaxonomically, the strain contained ll-diaminopimelic acid as the diagnostic diamino acid and MK-8(H4) as the predominant menaquinone. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and an unknown phospholipid. The major cellular fatty acids were iso-C16 : 0, C17 : 1 cis-9, C15 : 0 and iso-C15 : 0. The DNA G+C content was 73.7 mol%. On the basis of 16S rRNA gene sequence analysis, strain IR27-S3T was closely related to Nocardioides mesophilus MSL-22T (98.1 % 16S rRNA gene sequence similarity), Marmoricola bigeumensis MSL-05T (97.2 %) and Nocardioides jensenii DSM 20641T (96.5 %). On the basis of fatty acid analysis, phylogenetic analysis and phenotypic data, the isolate should be classified in a novel species of the genus Nocardioides, for which the name Nocardioides iriomotensis sp. nov. is proposed. The type strain is IR27-S3T ( = NBRC 105384T  = KACC 14926T).

A Gram-stain-positive, aerobic, non-motile, non-spore-forming, short rod-shaped actinobacterium, designated strain PB243T, was isolated from grass soil sampled in Daejeon, Republic of Korea. Comparative 16S rRNA gene sequence studies showed the isolate was clearly affiliated with the class Actinobacteria , and most closely related to Amnibacterium kyonggiense KEMC 51201-037T, showing 98.8 % 16S rRNA gene sequence similarity. Cells of strain PB243T formed yellow colonies on R2A agar, contained MK-11 and MK-12 as the predominant menaquinones, l-2,4-diaminobutyric acid as the diagnostic cell-wall diamino acid, and anteiso-C15 : 0 and iso-C16 : 0 among the major fatty acids. The acyl type of the muramic acid was acetyl. The G+C content of the genomic DNA of strain PB243T was 71.5 mol%. Thus, the combined genotypic and phenotypic data supported the conclusion that strain PB243T represents a novel species of the genus Amnibacterium , for which the name Amnibacterium soli sp. nov. is proposed. The type strain is PB243T ( = KCTC 33147T = JCM 19015T).

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).

Lactobacillus Kefiri

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).

Phyletic Line

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).

Two aerobic, Gram-reaction-negative, non-spore-forming bacterial strains, 4M29T and 4M40T, were isolated from cotton composts. The two strains grew in the presence of 0–5 % (w/v) NaCl (optimum growth in the absence of NaCl), at pH 6.0–8.0 (optimum, pH 7.0) and at 15–45 °C (optimum, 30 °C). The strains shared 97.1 % 16S rRNA gene sequence similarity. Strains 4M29T and 4M40T showed the next highest levels of 16S rRNA gene sequence similarity to Parapedobacter koreensis Jip14T (95.6 and 94.4 %, respectively) and Parapedobacter soli DCY14T (95.2 and 93.8 %). The level of DNA–DNA relatedness between strains 4M29T and 4M40T was 38 %. The two strains contained iso-C15 : 0, summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1 ω7c) and iso-C17 : 0 3-OH as major fatty acids, MK-7 as the major respiratory quinone, homospermidine as the only polyamine and phosphatidylethanolamine as the major polar lipid. The DNA G+C contents of strains 4M29T and 4M40T were 47.6 and 48.6 mol%, respectively. On the basis of phylogenetic and phenotypic data, strains 4M29T and 4M40T are considered to represent two novel species of the genus Parapedobacter, for which the names Parapedobacter luteus sp. nov. (type strain 4M29T =KACC 10955T =JCM 15977T) and Parapedobacter composti sp. nov. (type strain 4M40T =KACC 10972T =JCM 15978T) are proposed.

A novel halotolerant actinomycete, strain Chem15T, was isolated from soil around Inche-Broun hypersaline wetland; its taxonomic position was determined based on a polyphasic approach. Strain Chem15T was strictly aerobic and tolerated NaCl up to 12.5 %. The optimum temperature and pH for growth were 28–30 °C and pH 7.0–7.5, respectively. The cell wall of strain Chem15T contained meso-diaminopimelic acid as diamino acid and galactose, arabinose and ribose as whole-cell sugars. The major phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannosides. The cellular fatty acids profile consisted of C16 : 0, iso-C18 : 0, C18 : 0 10-methyl and C18 : 1ω9c, and the major respiratory quinone was MK-8(H4cycl). The G+C content of the genomic DNA was 68.0 mol%. The novel strain constituted a distinct phyletic line within the genus Nocardia, based on 16S rRNA gene sequence analysis, and was closely associated with Nocardia sungurluensis DSM 45714T and Nocardia alba DSM 44684T (98.2 and 98.1 % 16S rRNA gene sequence similarity, respectively). However DNA–DNA relatedness and phenotypic data demonstrated that strain Chem15T was clearly different from closely related species of the genus Nocardia. It is concluded that the organism should be classified as a representative of a novel species of the genus Nocardia, for which the name Nocardia halotolerans sp. nov. is proposed. The type strain is Chem15T ( = IBRC-M 10490T = LMG 28544T).

Polar Lipid Profile

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).

Actinomycete Strain

A moderately halophilic actinomycete strain, designated AH97T, was isolated from Saharan soil in the Hoggar region (south Algeria) and was subjected to polyphasic taxonomic characterization. The morphological and chemotaxonomic characteristics of the strain were consistent with those of the genus Actinoalloteichus. Results of 16S rRNA gene sequence comparison revealed that strain AH97T shared the highest degree of 16S rRNA gene sequence similarity with Actinoalloteichus hymeniacidonis DSM 45092T (99.3 %) and Actinoalloteichus nanshanensis DSM 45655T (98.7 %). However, DNA–DNA hybridization studies showed only 26.5 % relatedness with A. hymeniacidonis DSM 45092T and 28.0 % with A. nanshanensis DSM 45655T. The genotypic and phenotypic data showed that strain AH97T represents a novel species of the genus Actinoalloteichus, for which the name Actinoalloteichus hoggarensis sp. nov. is proposed, with AH97T ( = DSM 45943T = CECT 8639T) as the type strain.
