Genotypic Analysis

Two strains of bacteria isolated from the blood of French domestic cows were found to be similar to Bartonella species on the basis of phenotypic characteristics. Genotypic analysis based on sequence comparison of the 16S rRNA and citrate synthase (gltA) genes and on DNA–DNA hybridization showed that the two isolates represent a distinct and new species of Bartonella. Moreover, the phylogenetic analysis inferred from comparison of 16S rRNA and gltA sequences demonstrated that the new Bartonella species is related to other ruminant-derived Bartonella species. The name Bartonella chomelii is proposed for the new species. The type strain of Bartonella chomelii sp. nov. is A828T (=CIP 107869T=CCUG47497T).

Degrading Bacterium

A phenanthrene-degrading bacterium, strain TKPT, was isolated from a fly ash dumping site of the thermal power plant in Panki, Kanpur, India, by an enrichment culture method using phenanthrene as the sole source of carbon and energy. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belonged to the genus Sphingobium, as it showed highest sequence similarity to Sphingobium herbicidovorans DSM 11019T (97.3 %) and Sphingomonas cloacae JCM 10874T (96.5 %), compared with only 91–93 % similarity to members of other genera such as Sphingomonas sensu stricto, Novosphingobium, Sphingopyxis and Sphingosinicella. In DNA–DNA hybridization experiments with strains that were closely related phylogenetically and in terms of 16S rRNA gene sequences, i.e. Sphingobium herbicidovorans DSM 11019T and Sphingomonas cloacae JCM 10874T, strain TKPT showed less than 70 % relatedness. Strain TKPT contained sphingoglycolipids SGL-1 and SGL-2 and 18 : 1ω7c as the predominant fatty acid, with 16 : 0 as a minor component and 14 : 0 2-OH as the major 2-hydroxy fatty acid. Thus, phylogenetic analysis, DNA–DNA hybridization, fatty acid and polar lipid profiles and differences in physiological and morphological features from the most closely related members of the Sphingobium group showed that strain TKPT represents a distinct species of Sphingobium. The name Sphingobium fuliginis sp. nov. is proposed, with the type strain TKPT (=MTCC 7295T=CCM 7327T). Sphingomonas cloacae JCM 10874T formed a coherent cluster with members of Sphingobium, did not reduce nitrate to nitrite and had a fatty acid profile similar to those of Sphingobium species; hence Sphingomonas cloacae should be transferred to the genus Sphingobium as Sphingobium cloacae comb. nov., with the type strain JCM 10874T (=DSM 14926T).

Three Gram-negative, rod-shaped, non-spore-forming bacteria (strains CCUG 52769T, CCUG 52770 and CCUG 52771) isolated from haemodialysis water were characterized taxonomically, together with five strains isolated from industrial waters (CCUG 52428, CCUG 52507, CCUG 52575T, CCUG 52590 and CCUG 52631). Phylogenetic analysis based on 16S rRNA gene sequences indicated that these isolates belonged to the class Betaproteobacteria and were related to the genus Pelomonas, with 16S rRNA gene sequence similarities higher than 99 % with the only species of the genus, Pelomonas saccharophila and to Pseudomonas sp. DSM 2583. The type strains of Mitsuaria chitosanitabida and Roseateles depolymerans were their closest neighbours (97.9 and 97.3 % 16S rRNA gene sequence similarity, respectively). Phylogenetic analysis was also performed for the internally transcribed spacer region and for three genes [hoxG (hydrogenase), cbbL/cbbM (Rubisco) and nifH (nitrogenase)] relevant for the metabolism of the genus Pelomonas. DNA–DNA hybridization, major fatty acid composition and phenotypical analyses were carried out, which included the type strain of Pelomonas saccharophila obtained from different culture collections (ATCC 15946T, CCUG 32988T, DSM 654T, IAM 14368T and LMG 2256T), as well as M. chitosanitabida IAM 14711T and R. depolymerans CCUG 52219T. Results of DNA–DNA hybridization, physiological and biochemical tests supported the conclusion that strains CCUG 52769, CCUG 52770 and CCUG 52771 represent a homogeneous phylogenetic and genomic group, including strain DSM 2583, clearly differentiated from the industrial water isolates and from the Pelomonas saccharophila type strain. On the basis of phenotypic and genotypic characteristics, these strains belong to two novel species within the genus Pelomonas, for which the names Pelomonas puraquae sp. nov. and Pelomonas aquatica sp. nov. are proposed. The type strains of Pelomonas puraquae sp. nov. and Pelomonas aquatica sp. nov. are CCUG 52769T (=CECT 7234T) and CCUG 52575T (=CECT 7233T), respectively.

Phylogenetic analysis of ‘Sarraceniospora aurea’ NBRC 14752 and strain NBRC 15120, based on 16S rRNA gene sequences, revealed that these organisms are related to members of the genus Actinocorallia. These organisms contained glutamic acid, alanine and meso-diaminopimelic acid as cell-wall amino acids and the menaquinones MK-9(H4), MK-9(H6) and MK-9(H8). The chemotaxonomic characteristics of the strains were consistent with those of the genus Actinocorallia. However, DNA–DNA hybridization and phenotypic characteristics revealed that the strains differed from the recognized species of the genus Actinocorallia. Therefore, we propose that ‘Sarraceniospora aurea’ NBRC 14752 and strain NBRC 15120 be reclassified in the genus Actinocorallia as a novel species, Actinocorallia aurea sp. nov. (type strain NBRC 14752T=DSM 44434T).

Four Gram-negative, motile, rod-shaped bacterial strains were isolated from soil samples collected from south-east China. A taxonomic study including phylogenetic analysis based on 16S rRNA gene sequences and phenotypic characteristics was performed. DNA G+C contents of the four strains were 63–66 mol%. Their predominant ubiquinone was Q-8. The fatty acid profiles contained C16 : 1 ω7c (36·9–54·7 %) and C16 : 0 (22·8–25·5 %) as the major components. Based on their phenotypic characteristics, phylogenetic position as determined by 16S rRNA gene sequence analysis and DNA–DNA hybridization results, the four isolates are considered to represent four novel species of the genus Massilia, for which the names Massilia dura sp. nov. (type strain 16T=CCTCC AB 204070T=KCTC 12342T), Massilia albidiflava sp. nov. (type strain 45T=CCTCC AB 204071T=KCTC 12343T), Massilia plicata sp. nov.

An alkaliphilic actinomycete strain, designated YIM 80379T, was isolated from a soil sample collected from the eastern desert of Egypt and subjected to polyphasic taxonomy. The strain produced substrate and aerial mycelia on different media, with an optimum pH for growth of 9·5–10 and scarce or no growth at pH 7. Strain YIM 80379T contained meso-diaminopimelic acid, no diagnostic sugars, type PIII phospholipids and MK-10(H6) and MK-10(H8) as the predominant menaquinones. All of these characters assign isolate YIM 80379T consistently to the genus Nocardiopsis. This was confirmed by 16S rDNA analysis. It can be differentiated from all Nocardiopsis species with validly published names by phenotypic characteristics, phylogenetic analysis and DNA–DNA hybridization results. On the basis of polyphasic evidence, a novel species, Nocardiopsis alkaliphila sp. nov., is proposed. The type strain of the species is YIM 80379T (=CCTCC AA001031T=DSM 44657T).

Two actinomycete strains, designated LIPI11-2-Ac034T and LIPI11-2-Ac042T, were isolated from leaf litter collected from Cibodas Botanical Garden, West Java, Indonesia. Phylogenetic analysis based on 16S rRNA gene sequences suggested that both isolates belong to the genus Actinoplanes. These isolates were closely related to Actinoplanes ferrugineus and Actinoplanes durhamensis with similarity values of 98.2 % and 97.7 % respectively, for strain LIPI11-2-Ac034T, and 99.0 % and 97.4–97.7 % respectively for strain LIPI11-2-Ac042T. Both isolates grew well on ISP 7 medium with brown soluble pigment production. Spores were motile and sporangia were irregular. The isolates contained meso-diaminopimelic acid in cell-wall hydrolysates, and mannose, glucose and galactose in whole-cell hydrolysates. The predominant menaquinone of strain LIPI11-2-Ac034T was MK-9(H4) while that of strain LIPI11-2-Ac042T was MK-9(H6). The major cellular fatty acids were iso-C16 : 0, iso-C15 : 0 and anteiso-C15 : 0 for strain LIPI11-2-Ac034T, and iso-C16 : 0, anteiso-C15 : 0, iso-C15 : 0 and anteiso-C17 : 0 for strain LIPI11-2-Ac042T. Phosphatidylethanolamine was detected as the diagnostic polar lipid. The DNA G+C contents of strains LIPI11-2-Ac034T and LIPI11-2-Ac042T were 71.5 and 70.7 mol%, respectively. Based on the differential phenotypic characteristics and the results of DNA–DNA hybridization and phylogenetic analysis, it is proposed that strains LIPI11-2-Ac034T and LIPI11-2-Ac042T represent two novel species of the genus Actinoplanes, for which the names Actinoplanes tropicalis sp. nov. (type strain LIPI11-2-Ac034T = InaCC A459T = NBRC 110973T) and Actinoplanes cibodasensis sp. nov. (type strain LIPI11-2-Ac042T = InaCC A458T = NBRC 110974T) are proposed.

Two rod-shaped, non-motile bacteria were isolated from two separate salt mines in Yunnan, south-western China. These strains, designated YIM D15T and YIM J21T, were Gram-negative and moderately halophilic. The two strains required 6–10 % NaCl (w/v; optimal) for growth. The DNA G+C contents of strains YIM D15T and YIM J21T were 49.0 mol% and 48.4 mol%, respectively. The predominant isoprenoid quinone was MK-7. The polar lipid profiles of strains YIM D15T and YIM J21T were composed predominantly of diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, three unknown polar lipids and one glycolipid. Minor amounts of other lipids were also detectable. The predominant cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0, iso-C17 : 1ω9c/10 methyl-C16 : 0 and C16 : 1ω7c/C16 : 1ω6c. Phylogenetic analysis based on 16S rRNA gene sequence comparisons showed that the two isolates formed a distinct clade with the genus Fodinibius (in the phylum Bacteroidetes ) and were related to the species Fodinibius salinus , with sequence similarities of 91.9–92.4 %. Analyses of 16S rRNA gene sequences revealed that strains YIM D15T and YIM J21T were related to each other (97.3 % sequence similarity). The DNA–DNA hybridization relatedness between the two isolates was 34 %. On the basis of the phylogenetic analysis, DNA–DNA hybridization relatedness, phenotypic and chemotaxonomic characteristics, strains YIM D15T and YIM J21T should be classified as members of a novel genus and as two novel species, for which the names Aliifodinibius roseus gen. nov., sp. nov. (type strain YIM D15T = ACCC 10715T = KCTC 23442T) and Aliifodinibius sediminis sp. nov. (type strain YIM J21T = ACCC 10714T = DSM 21194T) are proposed.

Three strains, designated as LB1R34T, LB3P52T and ZT4R6T, were isolated from glaciers located on the Tibetan Plateau, PR China. The strains were Gram-stain-negative, aerobic, rod-shaped, non-motile and yellow. Phylogenetic analysis based on the 16S rRNA gene and genomic sequences indicated that they were related to the members of the genus Flavobacterium . The 16S rRNA gene sequences similarities between the three strains were 92.31–96.93 %. The average nucleotide identity values and digital DNA–DNA hybridization values between these three strains and their closest relatives were 76.80–91.33 % and 21.3–44.2 %, respectively. LB1R34T, LB3P52T and ZT4R6T contained MK-6 as the major menaquinone, summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) and iso-C15 : 0 as the major fatty acids. Phosphatidylethanolamine was present in their polar lipids profiles. On the basis of the phenotypic characteristics, he results of phylogenetic analysis and genotypic data, three novel species, Flavobacterium restrictum sp. nov. (type strain=LB1 R34T=CGMCC 1.11493T=NBRC 113650T), Flavobacterium rhamnosiphilum sp. nov. (type strain=LB3 P52T=CGMCC 1.11446T=NBRC 113776T) and Flavobacterium zepuense sp. nov.

A novel Gram-staining-positive, aerobic, endospore-forming, rod-shaped bacterial strain, YN2T, was isolated from ripened Pu'er tea. Phylogenetic analysis of 16S rRNA gene sequences showed that the strain represented a novel species of the genus Paenibacillus. The strains most closely related to strain YN2T were Paenibacillus vulneris JCM 18268T and Paenibacillus rigui JCM 16352T, with 16S rRNA similarities of 98.6 and 95.5 %, respectively. Chemotaxonomic data supported the affiliation of the new isolate to the genus Paenibacillus, including MK-7 as the major menaquinone, DNA G+C content of 51 mol%, cell-wall type A1γ (meso-diaminopimelic acid as the diagnostic diamino acid) and anteiso-C15 : 0 and iso-C16 : 0 as the major fatty acids. Major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmonomethylethanolamine and phospholipid. Strain YN2T could be differentiated from recognized species of the genus Paenibacillus based on phenotypic characteristics, chemotaxonomic differences, phylogenetic analysis and DNA–DNA hybridization data. On the basis of evidence from this polyphasic study, Paenibacillus yunnanensis sp. nov., is proposed, with strain YN2T ( = CGMCC 1.12968T = JCM 30953T) as the type strain.
