Type Strains

A novel bacterial strain, designated ZLT, isolated from a warm spring in Jhonglun, Taiwan, was characterized by using a polyphasic taxonomic approach. The novel strain had chemotaxonomic and morphological properties consistent with its classification in the genus Paenibacillus. Cells were Gram-variable, aerobic, sporulating, motile rods. 16S rRNA gene sequence analysis demonstrated that this novel isolate was unique, showing 94.3 % sequence similarity to Paenibacillus assamensis GPTSA 11T and lower levels to Paenibacillus timonensis 2301032T (94.0 %), Paenibacillus macerans ATCC 8244T (93.3 %), Paenibacillus barengoltzii SAFN-016T (93.3 %) and Paenibacillus sanguinis 2301083T (93.2 %). The novel isolate could be distinguished from the type strains of all of these species based on a range of phenotypic data. The major cellular phospholipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and one unknown phosphoglycolipid. The predominant isoprenologue was an unsaturated menaquinone with seven isoprene units (MK-7). The major fatty acids of strain ZLT were C16 : 0 (33.5 %), anteiso-C15 : 0 (32.5 %) and iso-C16 : 0 (9.3 %). The G+C content of the genomic DNA was 49.2 mol%. It is evident from the genotypic and phenotypic data that strain ZLT should be classified as representing a novel species of the genus Paenibacillus, for which the name Paenibacillus fonticola sp. nov. is proposed. The type strain is ZLT (=BCRC 17579T=LMG 23577T).

Type Strains

A cholesterol side-chain-cleaving bacterial strain, AD-6T, was isolated from fresh faeces of a clouded leopard (Neofelis nebulosa) and was studied using a polyphasic taxonomic approach. 16S rRNA gene sequence analysis showed that the novel strain formed a distinct subline within the genus Gordonia, its closest neighbours being the type strains of Gordonia cholesterolivorans, Gordonia sihwensis and Gordonia hydrophobica, with sequence similarity values of 98.2, 97.8 and 97.6 %, respectively. The gyrB gene sequence of strain AD-6T exhibited similarities of 77–91 % with those of the type strains of recognized species of the genus Gordonia, being most similar to the type strains of G. sihwensis, G. hydrophobica and Gordonia hirsuta (91, 87 and 84 % similarity, respectively). The results of whole-cell fatty acid analyses and DNA–DNA relatedness data readily distinguished the new isolate from its nearest neighbours. Strain AD-6T is therefore considered to represent a novel species of the genus Gordonia, for which the name Gordonia neofelifaecis sp. nov. is proposed. The type strain is AD-6T (=NRRL B-59395T=CCTCC AB-209144T).

A soil isolate, strain CC-AB07T, was characterized using a polyphasic approach. This organism had chemotaxonomic and morphological properties consistent with its classification in the genus Gordonia. 16S rRNA gene sequence analysis showed that the novel strain formed a monophyletic branch at the periphery of the evolutionary radiation occupied by the genus Gordonia, its closest neighbours being the type strains of Gordonia alkanivorans, Gordonia amicalis, Gordonia bronchialis, Gordonia desulfuricans, Gordonia polyisoprenivorans and Gordonia rhizosphera. The novel isolate was distinguished from all of these type strains using a range of phenotypic properties and by gyrB gene sequence analysis. It was evident from the genotypic and phenotypic data that strain CC-AB07T should be classified as representing a novel species in the genus Gordonia, for which the name Gordonia soli sp. nov. is proposed. The type strain is CC-AB07T (=BCRC 16810T=DSM 44995T).

Two bacterial isolates from Kuwaiti soil contaminated by crude oil were analysed by using a polyphasic taxonomic approach. The isolates, designated OFN N11 and OFN N12T, were shown to have molecular, chemical and morphological properties typical of members of the genus Nocardia. Based on a multigenic approach that included 16S rRNA, hsp65 and sod gene sequencing, these novel isolates formed a monophyletic clade within the genus Nocardia. The closest species was Nocardia ignorata (with 99.4 %, 99.5 %, 98.6 % gene sequence similarity to the 16S rRNA, hsp65 and sod genes, respectively). The novel isolates could be distinguished phenotypically from the type strains of recognized species of the genus Nocardia. The novel isolates were not related to the type strain of N. ignorata in DNA–DNA hybridization experiments (26 % relatedness). On the basis of these genotypic and phenotypic data, the two isolates appear to represent a novel species, for which the name Nocardia coubleae sp. nov. is proposed. The type strain is OFN N12T (=DSM 44960T=CIP 108996T).

A Gram-reaction-positive, rod-shaped, non-motile, non-spore-forming bacterium (strain BX5-10T) was isolated from the soil of a ginseng field on Baekdu Mountain in Jilin district, China. The taxonomic position of this bacterium was determined in an investigation based on a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain BX5-10T was shown to belong to the family Nocardioidaceae and to be most closely related to Nocardioides plantarum NCIMB 12834T (96.5 % sequence similarity), Nocardioides dokdonensis KCTC 19309T (96.2 %) and Nocardioides fonticola NAA-13T (95.1 %). Strain BX5-10T was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in its cell-wall peptidoglycan, MK-8(H4) as the predominant menaquinone and C18 : 1ω9c, C16 : 0 and C17 : 1ω8c as its major fatty acids. The G+C content of the genomic DNA was 70.3 mol%. The novel strain could be differentiated genotypically and phenotypically from all recognized species of the genus Nocardioides. Based on the results of the phylogenetic analyses and the genotypic and phenotypic data, a novel species, Nocardioides ginsengagri sp. nov., is proposed. The type strain is BX5-10T ( = KCTC 19467T = DSM 21362T).

Two facultatively aerobic, heterotrophic bacteria capable of degrading pectin, xylan, laminarin and some other polysaccharides were obtained from the acidic Sphagnum peat bog Bakchar, in western Siberia, Russia, and were designated strains TPT18T and TPT56T. Cells of these isolates are Gram-negative, non-motile, long rods that are covered by large capsules. On ageing, they transform into spherical L-forms. Strains TPT18T and TPT56T are acido- and psychrotolerant organisms capable of growth at pH 4.2–8.2 (with an optimum at pH 6.0–6.5) and at 2–33 °C (with an optimum at 20 °C). The major fatty acids are iso-C15 : 0, anteiso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c); the quinones are MK-7 and MK-6. Comparative 16S rRNA gene sequence analysis revealed that the novel strains share 97 % sequence similarity and belong to the family Sphingobacteriaceae; however, they are related only distantly to members of the genera Pedobacter (91.8–93.3 % similarity) and Sphingobacterium (89.6–91.2 % similarity). The DNA G+C content of strains TPT18T and TPT56T is 42.4 and 46.1 mol%, respectively. The low DNA–DNA hybridization value (42 %) and a number of phenotypic differences between strains TPT18T and TPT56T indicated that they represent two separate species. Since the two isolates are clearly distinct from all currently described members of the family Sphingobacteriaceae, we propose a novel genus, Mucilaginibacter gen. nov., containing two novel species, Mucilaginibacter gracilis sp. nov. and Mucilaginibacter paludis sp. nov. The type strains of Mucilaginibacter gracilis and Mucilaginibacter paludis are respectively TPT18T (=ATCC BAA-1391T =VKM B-2447T) and TPT56T (=ATCC BAA-1394T =VKM B-2446T).

The taxonomic position of an actinomycete isolated from a brown hypermagnesian ultramafic soil was examined using a polyphasic approach. The organism, which was designated SBHS Strp1T, was found to have chemical and morphological properties typical of Amycolatopsis strains. It was most closely associated with Amycolatopsis kentuckyensis, Amycolatopsis lexingtonensis, Amycolatopsis rifamycinica, Amycolatopsis pretoriensis and Amycolatopsis tolypomycina on the basis of 16S rRNA gene sequence data, and showed a unique pattern of phenotypic properties that distinguished it from the type strains of these taxa. The combined genotypic and phenotypic data show that the organism merits description as a novel species of Amycolatopsis. The name proposed for the novel species is Amycolatopsis plumensis sp. nov.; the type strain is SBHS Strp1T (=DSM 44776T=NRRL B-24324T).

A bacterial strain designated TNR-22T was isolated from a freshwater river in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain TNR-22T were facultatively anaerobic, Gram-stain-negative, rod-shaped, motile by a single polar flagellum and formed cream-coloured colonies. Growth occurred at 4–45 °C (optimum, 25–30 °C), with 0–1.0 % (w/v) NaCl (optimum, 0.5 %) and at pH 7.0–8.0 (optimum, pH 7.0). Strain TNR-22T did not form nodules on Macroptilium atropurpureum. The nifH gene encoding denitrogenase reductase was not detected by PCR. The major fatty acids (>10 %) of strain TNR-22T were C18 : 1ω7c and C16 : 0. The DNA G+C content was 60.3 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, diphosphatidylglycerol, an uncharacterized aminoglycolipid and an uncharacterized phospholipid. Comparative analysis of 16S rRNA gene sequences showed that strain TNR-22T constituted a distinct branch within the genus Rhizobium , showing the highest level of sequence similarity with Rhizobium rosettiformans W3T (96.3 %). Phenotypic characteristics of the novel strain also differed from those of the most closely related species of the genus Rhizobium . On the basis of the genotypic, chemotaxonomic and phenotypic data, strain TNR-22T represents a novel species in the genus Rhizobium , for which the name Rhizobium alvei sp. nov. is proposed. The type strain is TNR-22T ( = BCRC 80408T = LMG 26895T = KCTC 23919T).

A novel betaproteobacterium, designated strain Ch07T, was isolated from granules from the wastewater-treatment bioreactor of an alcohol fermentation factory in South Korea. In order to determine its taxonomic position, the novel strain was characterized using a polyphasic approach. The new strain was Gram-negative, facultatively anaerobic, non-spore-forming, motile and short rod-shaped. 16S rRNA gene sequence analysis revealed that strain Ch07T belonged to the class Betaproteobacteria, being related to Pusillimonas noertemannii BN9T (gene sequence similarity 97.30 %), Achromobacter xylosoxidans subsp. xylosoxidans DSM 10346T (97.09 %), Bordetella pertussis DSM 5571T (97.01 %), Pigmentiphaga kullae DSM 13608T (96.68 %) and Castellaniella defragrans DSM 1214T (96.47 %). The results of DNA–DNA hybridization tests showed that reassociation values were less than 62 % with respect to these closely related type strains. Chemotaxonomic data showed that strain Ch07T possessed ubiquinone Q-8. The G+C content of the genomic DNA was 67.9±0.1 mol%. The major polyamine of strain Ch07T was putrescine. The major polar lipids of strain Ch07T were phosphatidylethanolamine, followed by diphosphatidylglycerol and phosphatidylglycerol. When strain Ch07T was incubated on tryptic soy agar, the major cellular fatty acids were C16 : 0, C17 : 0 cyclo, summed feature 3 (C16 : 1 ω7c/iso C15 : 0 2-OH) and summed feature 5 (C18 : 1 ω7c/ω9t/ω12t). The results of DNA–DNA hybridizations, in combination with the chemotaxonomic and physiological data, demonstrated that strain Ch07T represents a novel species of a new genus, for which the name Parapusillimonas granuli gen. nov., sp. nov. is proposed. The type strain of the type species is Ch07T (=KCTC 12668T=LMG 24012T).
