Gene Sequence Analysis

A brown-coloured bacterium was isolated from photoheterotrophic (benzoate) enrichments of flooded paddy soil from Andhra Pradesh, India. On the basis of 16S rRNA gene sequence analysis, strain JA2T was shown to belong to the class Betaproteobacteria, related to Rubrivivax gelatinosus (99 % sequence similarity). Cells of strain JA2T are Gram-negative, motile rods with monopolar single flagella. The strain contained bacteriochlorophyll a and most probably the carotenoids spirilloxanthin and sphaeroidene, but did not have internal membrane structures. Intact cells had absorption maxima at 378, 488, 520, 590, 802 and 884 nm. No growth factors were required. Strain JA2T grew on benzoate, 2-aminobenzoate (anthranilate), 4-aminobenzoate, 4-hydroxybenzoate, phthalate, phenylalanine, trans-cinnamate, benzamide, salicylate, cyclohexanone, cyclohexanol and cyclohexane-2-carboxylate as carbon sources and/or electron donors. The DNA G+C content was 74.9 mol%. Based on DNA–DNA hybridization studies, 16S rRNA gene sequence analysis and morphological and physiological characteristics, strain JA2T is different from representatives of other photosynthetic species of the Betaproteobacteria and was recognised as representing a novel species, for which the name Rubrivivax benzoatilyticus sp. nov. is proposed. The type strain is JA2T (=ATCC BAA-35T=JCM 13220T=MTCC 7087T).

A bacterial strain, DC-186T, isolated from home-made compost, was characterized for its phenotypic and phylogenetic properties. The isolate was a Gram-negative rod that was able to grow at 15–36 °C and pH 5.5–8.0. Strain DC-186T was positive in tests for catalase, oxidase and β-galactosidase activities and aesculin hydrolysis. The predominant fatty acids were the summed feature C16 : 1/iso-C15 : 0 2-OH (42 %) and iso-C15 : 0 (26 %), the major respiratory quinone was menaquinone-7 and the genomic DNA G+C content was 42 mol%. 16S rRNA gene sequence analysis and phenetic characterization indicated that this organism belongs to the phylum Bacteroidetes and revealed its affiliation to the family Sphingobacteriaceae. Of recognized taxa, strain DC-186T was most closely related to Sphingobacterium daejeonense (90 % sequence similarity) based on 16S rRNA gene sequence analysis. The low 16S rRNA gene sequence similarity with other recognized taxa and the identification of distinctive phenetic features for this isolate support the definition of a new genus within the family Sphingobacteriaceae. The name Pseudosphingobacterium domesticum gen. nov., sp. nov. is proposed, with strain DC-186T (=CCUG 54353T=LMG 23837T) as the type strain.

Two anaerobic, pigmented, non-spore-forming, Gram-stain-negative, rod-shaped strains isolated from the human oral cavity, OMA31T and OMA130, were characterized by determining their phenotypic and biochemical features, cellular fatty acid profiles and phylogenetic positions based on 16S rRNA gene sequence analysis. 16S rRNA gene sequence analysis showed that the new isolates belonged to a single species of the genus Prevotella. The two isolates showed 100 % 16S rRNA gene sequence similarity with each other and were most closely related to Prevotella intermedia ATCC 25611T with 96.4 % 16S rRNA gene sequence similarity; the next most closely related strains to the isolates were Prevotella pallens AHN 10371T (96.1 %) and Prevotella falsenii JCM 15124T (95.3 %). Phenotypic and biochemical characteristics of the isolates were the same as those of P. intermedia JCM 12248T, P. falsenii JCM 15124T and Prevotella nigrescens JCM 12250T. The isolates could be differentiated from P. pallens JCM 11140T by mannose fermentation and α-fucosidase activity. Conventional biochemical tests were unable to differentiate the new isolates from P. intermedia, P. falsenii and P. nigrescens. However, hsp60 gene sequence analysis suggested that strain OMA31T was not a representative of P. intermedia, P. pallens, P. falsenii or P. nigrescens. Based on these data, a novel species of the genus Prevotella, Prevotella aurantiaca sp. nov., is proposed, with OMA31T (=JCM 15754T=CCUG 57723T) as the type strain.

Two bacterial strains isolated from chicken caecum, C46T and C47, were characterized using a polyphasic taxonomic approach that included analysis of the phenotypic and biochemical features, cellular fatty acid profiles, menaquinone profiles and phylogenetic position (using 16S rRNA gene sequence analysis). The 16S rRNA gene sequence analysis showed that these strains belonged to the family Porphyromonadaceae. These strains shared 100 % 16S rRNA gene sequence similarity with each other and were related to Parabacteroides distasonis (showing 86 % sequence similarity). The strains were found to be obligately anaerobic, non-pigmented, non-spore-forming, non-motile, Gram-negative rods. Growth of the strains was inhibited on medium containing 20 % bile. The major menaquinones of the isolates were MK-11 and MK-12. This menaquinone composition was different from those of other genera of the family Porphyromonadaceae, such as Parabacteroides (in which the predominant menaquinones are MK-9 and MK-10), Porphyromonas (MK-9 and MK-10) and Tannerella (MK-10 and MK-11). This is an important chemotaxonomic characteristic of these micro-organisms. The DNA G+C content of strain C46T is 52.0 mol%. On the basis of these data, strains C46T and C47 represent a novel genus and species, for which the name Barnesiella viscericola gen. nov., sp. nov. is proposed. The type strain of Barnesiella viscericola is C46T (=JCM 13660T=DSM 18177T).

A Gram-positive, rod-shaped, endospore-forming organism, strain CCUG 47242T, was isolated from a sample of industrial starch production in Sweden. 16S rRNA gene sequence analysis demonstrated that this isolate was moderately related to species of the genus Paenibacillus, with <94·4 % sequence similarity to all other hitherto described Paenibacillus species. Strain CCUG 47242T showed the greatest sequence similarity (96·5 %) to ‘Paenibacillus hongkongensis’ HKU3, a strain with a name that has not yet been validly published. Chemotaxonomic data [major menaquinone, MK-7 (98 %); major polar lipids, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, lysyl-phosphatidylglycerol, two unknown phospholipids, four unknown aminophospholipids; major fatty acids, iso-C16 : 0 and anteiso-C15 : 0] showed some significant differences when compared with the type species of the genus Paenibacillus, Paenibacillus polymyxa. Physiological and biochemical tests allowed clear phenotypic differentiation of strain CCUG 47242T from strain HKU3. On the basis of 16S rRNA gene sequence analysis, in combination with chemotaxonomic data, strains CCUG 47242T and HKU3 represent two novel species of a new genus of endospore-forming bacteria for which we propose the names Cohnella thermotolerans gen. nov., sp. nov. (type strain CCUG 47242T=CIP 108492T=DSM 17683T) and Cohnella hongkongensis sp. nov. (type strain HKU3T=CCUG 49571T=CIP 107898T=DSM 17642T).

A yellow-pigmented, Gram-negative, rod-shaped, non-spore-forming bacterium, strain CC-TPE-1T, was isolated from oil-contaminated soil near an oil refinery located in Kaohsiung County, Taiwan. 16S rRNA gene sequence analysis of strain CC-TPE-1T showed highest sequence similarity to Novosphingobium naphthalenivorans TUT562T (98.1 %), N. panipatense SM16T (97.9 %) and N. mathurense SM117T (97.6 %) and lower (<97 %) sequence similarity to all other Novosphingobium species. DNA–DNA hybridizations of strain CC-TPE-1T with N. naphthalenivorans DSM 18518T, N. panipatense SM16T and N. mathurense SM117T showed low relatedness of 30 % (reciprocal 35 %), 29.1 % (reciprocal 30.6 %) and 35 % (reciprocal 23.6 %), respectively. The major respiratory quinone was ubiquinone Q-10, the predominant fatty acid was C18 : 1 ω7c (49.9 %) and three 2-hydroxy fatty acids, C14 : 0 2-OH (8.2 %), C15 : 0 2-OH (2.45 %) and C16 : 0 2-OH (1.05 %), were detected. Polar lipids consisted mainly of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, phosphatidyldimethylethanolamine, two sphingoglycolipids, phosphatidylmonomethylethanolamine and several unidentified lipids, and a yellow pigment was also detected. The polyamine pattern contained the single major compound spermidine. Characterization by 16S rRNA gene sequence analysis, physiological parameters, pigment analysis and polyamine, ubiquinone, polar lipid and fatty acid compositions revealed that strain CC-TPE-1T represents a novel species of the genus Novosphingobium, for which we propose the name Novosphingobium soli sp. nov., with the type strain CC-TPE-1T (=DSM 22821T =CCM 7706T =CCUG 58493T).

A novel bacterial strain designated B3AT, isolated from shrimp paste, was investigated by a polyphasic taxonomic approach. Cells stained Gram-positive and were aerobic, non-pigmented, sporulating and rod-shaped with a polar flagellum. 16S rRNA gene sequence analysis indicated that strain B3AT belonged to the class Bacilli and was a member of the family Bacillaceae. Strain B3AT shared low levels of 16S rRNA gene sequence similarity (<94.0 %) with members of other genera in the family Bacillaceae and was most closely related to Halalkalibacillus halophilus BH2T (93.8 % sequence similarity). The isolate was able to grow at 20–45 °C, with 0.5–15 % NaCl and at pH 6–9. Menaquinone with seven isoprene units (MK-7) was the major respiratory quinone and 16 : 0 iso, 15 : 0 anteiso and 14 : 0 iso were the major fatty acids. The major polar lipids were diphosphatidylglycerol and phosphatidylglycerol. The characteristic diamino acid of the peptidoglycan was meso-diaminopimelic acid. The DNA G+C content was 45.3 mol%. On the basis of 16S rRNA gene sequence analysis in combination with chemotaxonomic and physiological data, strain B3AT represents a novel genus and species in the family Bacillaceae for which the name Allobacillus halotolerans gen. nov., sp. nov. is proposed. The type strain of Allobacillus halotolerans is B3AT ( = BCRC 17939T  = LMG 24826T).

An ivory-coloured bacterium, designated strain 5YN7-3T, was isolated from a wetland, Yongneup, Korea. Cells of the strain were aerobic, Gram-stain-negative, non-motile and short rods. 16S rRNA gene sequence analysis demonstrated that strain 5YN7-3T belongs to the order Rhizobiales of the class Alphaproteobacteria and is closely related to Kaistia soli 5YN9-8T (97.8 %), Kaistia granuli Ko04T (97.6 %) and Kaistia adipata Chj404T (97.4 %). Strain 5YN7-3T showed DNA–DNA hybridization values of 28, 22 and 35 % with K. granuli Ko04T, K. soli 5YN9-8T and K. adipata Chj404T, respectively. The major fatty acids were C18 : 1 ω7c (51.2 %), C19 : 0 cyclo ω8c (25.0 %), C18 : 0 (12.9 %) and C16 : 0 (10.8 %) (>10 % of total fatty acids). Ubiquinone-10 was the major isoprenoid quinone and the DNA G+C content was 66.5 mol%. The phenotypic characteristics in combination with 16S rRNA gene sequence analysis and DNA–DNA hybridization data clearly define strain 5YN7-3T as a novel species of the genus Kaistia, for which the name Kaistia terrae sp. nov. is proposed. The type strain is 5YN7-3T (=KACC 12910T =DSM 21341T).

A bacterial strain isolated from human faeces, M-165T, was characterized in terms of its phenotypic and biochemical features, cellular fatty acid profile, menaquinone profile and phylogenetic position (based on 16S rRNA gene sequence analysis). A 16S rRNA gene sequence analysis showed that the isolate was a member of the genus Parabacteroides. Strain M-165T was closely related to Parabacteroides merdae strains, showing 98 % sequence similarity. The strain was obligately anaerobic, non-pigmented, non-spore-forming, non-motile, Gram-negative, rod-shaped and was able to grow on media containing 20 % bile. Although the phenotypic characteristics of the strain M-165T were similar to those of P. merdae, the isolate could be differentiated from P. merdae by means of API 20A tests for l-arabinose and l-rhamnose fermentation. DNA–DNA hybridization experiments revealed the genomic distinctiveness of the novel strain with respect to P. merdae JCM 9497T (⩽60 % DNA–DNA relatedness). The DNA G+C content of the strain is 47.6 mol%. On the basis of these data, strain M-165T represents a novel species of the genus Parabacteroides, for which the name Parabacteroides johnsonii sp. nov. is proposed. The type strain is M-165T (=JCM 13406T=DSM 18315T).
