Bacterium Strain

A coryneform bacterium (strain 1094T) was isolated from a wound swab taken from an 89-year-old female patient. Chemotaxonomic investigations suggested that this bacterium was related to the genera Actinomyces, Arcanobacterium and Actinobaculum. Phylogenetic analysis of 16S rRNA gene sequences showed that strain 1094T was most closely related to Actinomyces europaeus CCUG 32789 AT (94.3 % similarity). Phenotypically, the isolate could be separated from its closest phylogenetic neighbours on the basis of being positive for catalase, CAMP reaction, acid phosphatase, N-acetyl-β-glucosaminidase and raffinose fermentation. Based on the data presented, it is proposed that strain 1094T should be classified in a novel species, Actinomyces hominis sp. nov. The type strain is 1094T (=CCUG 57540T =DSM 22168T).

A novel strain, designated 311-10T, isolated from soil of Xinjiang, China, was characterized by using a polyphasic taxonomic approach. The isolate was Gram-negative, aerobic, rod-shaped, non-motile, oxidase-negative and catalase-positive. The predominant menaquinone of strain 311-10T was MK-7 and the genomic DNA G+C content was 47.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate formed a cluster with the genera Pontibacter and [Effluviibacter] in the phylum ‘Bacteroidetes’, with sequence similarities of 93.9–95.6 %. Phylogenetic evidence and the results of phenotypic, genotypic and chemotaxonomic analyses support the reclassification of [Effluviibacter] roseus as Pontibacter roseus comb. nov. (type strain, SRC-1T=MTCC 7260T=DSM 17521T) and the establishment of a novel species, Pontibacter xinjiangensis sp. nov., with strain 311-10T (=CCTCC AB 207200T=NRRL B-51335T) as the type strain.

Mycobacterium Simiae

Four strains isolated in the last 15 years were revealed to be identical in their 16S rRNA gene sequences to MCRO19, the sequence of which was deposited in GenBank in 1995. In a polyphasic analysis including phenotypic and genotypic features, the five strains (including MCRO19), which had been isolated in four European countries, turned out to represent a unique taxonomic entity. They are scotochromogenic slow growers and are genetically related to the group that included Mycobacterium simiae and 15 other species. The novel species Mycobacterium europaeum sp. nov. is proposed to accommodate these five strains. Strain FI-95228T ( = DSM 45397T  = CCUG 58464T) was chosen as the type strain. In addition, a thorough revision of the phenotypic and genotypic characters of the species related to M. simiae was conducted which leads us to suggest the denomination of the ‘Mycobacterium simiae complex’ for this group.

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).

A non-motile, yellow–orange-pigmented bacterial strain, designated HME6664T, was isolated from Lake Soyang, Republic of Korea. The major fatty acids of strain HME6664T were summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c; 44.7 %) and iso-C15 : 0 (20.2 %). The DNA G+C content was 40.8 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HME6664T formed a lineage within the genus Mucilaginibacter . Strain HME6664T was closely related to Mucilaginibacter ximonensis (96.7 %), Mucilaginibacter dorajii (96.5 %) and Mucilaginibacter lappiensis (96.3 %). On the basis of the evidence presented in this study, strain HME6664T represents a novel species of the genus Mucilaginibacter , for which the name Mucilaginibacter soyangensis sp. nov., is proposed. The type strain is HME6664T ( = KCTC 23261T = CECT 7824T).

Phenotypic Features

Halorubrum distributum (basonym, Halobacterium distributum) is an extremely halophilic, aerobic archaeon isolated from saline soils, which was described on the basis of phenotypic features of several strains. The designated type strain of the species (1mT=VKM B-1733T=JCM 9100T) was shown recently to differ from the other strains. In this study, Halorubrum distributum isolates have been characterized with regard to phenotypic features, polar lipid content, comparison of 16S rRNA gene sequences and DNA–DNA hybridization. On the basis of these data, a novel species that includes the other isolates is proposed, with the name Halorubrum terrestre sp. nov. The type strain of this novel species is 4pT (=VKM B-1739T=JCM 10247T). The DNA G+C content of this novel species is 64·2–64·9 mol% (64·4 mol% for the type strain).

A Gram-positive, non-motile, rod- or coccoid-shaped Isoptericola-like bacterium, strain DS-3T, was isolated from a soil sample from Dokdo, Korea, and its taxonomic position was investigated by a polyphasic approach. The organism grew optimally at 30 °C and pH 7.0–8.0. Strain DS-3T had the peptidoglycan type based on l-lys–d-Asp, and galactose, glucose, rhamnose and ribose as the whole-cell sugars. It contained MK-9(H4) as the predominant menaquinone and anteiso-C15 : 0 and iso-C15 : 0 as the major fatty acids. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and two unidentified glycolipids. The DNA G+C content was 74.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-3T was most closely related to members of the genus Isoptericola. Similarity values between the 16S rRNA gene sequences of strain DS-3T and the type strains of Isoptericola species ranged from 98.0 to 98.4 %. DNA–DNA relatedness values (11–23 %) and differential phenotypic properties demonstrated that strain DS-3T was distinguishable from recognized Isoptericola species. On the basis of phenotypic properties and phylogenetic and genetic distinctiveness, strain DS-3T represents a novel species in the genus Isoptericola, for which the name Isoptericola dokdonensis sp. nov. is proposed. The type strain is DS-3T (=KCTC 19128T=CIP 108921T).

An orange-pigmented bacterium, designated strain 13-9-B8T, was isolated from a seawater sample collected at Marado, Jeju Island, South Korea. The novel strain was Gram-staining-negative, non-motile, non-gliding, rod-shaped and aerobic. A phylogenetic analysis based on 16S rRNA gene sequences revealed that the strain clustered with members of the genus Lewinella of the family Saprospiraceae in the phylum Bacteroidetes and was most closely related to the species Lewinella marina (95.6 % similarity to the type strain). Strain 13-9-B8T grew optimally at 30 °C, pH 7.0 and with 2 % (w/v) NaCl. Strain 13-9-B8T contained MK-7 as the predominant menquinone and summed feature 3, iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The polar lipids detected in strain 13-9-B8T were phosphatidylethanolamine, one unidentified aminolipid, one unidentified phospholipid and eight unidentified lipids. The DNA G+C content of strain 13-9-B8T was 59.1 mol%. Based on phenotypic, chemotaxonomic and phylogenetic data presented, strain 13-9-B8T is considered to represent a novel species of the genus Lewinella, for which the name Lewinella xylanilytica sp. nov. is proposed. The type strain is 13-9-B8T ( = DSM 29526T = KCTC 32663T).

Three actinomycetes isolated from the surfaces of rocks in a medieval slate mine were examined in a polyphasic taxonomic study. Chemotaxonomic and morphological characteristics of the isolates were typical of strains of the genus Amycolatopsis. The isolates had identical 16S rRNA gene sequences and formed a distinct phyletic line towards the periphery of the Amycolatopsis mediterranei clade, being most closely related to Amycolatopsis rifamycinica. The organisms shared a wide range of genotypic and phenotypic markers that distinguished them from their closest phylogenetic neighbours. On the basis of these results, a novel species, Amycolatopsis saalfeldensis sp. nov., is proposed. The type strain is HKI 0457T (=DSM 44993T=NRRL B-24474T).

The taxonomic position of two actinomycete strains, LC2T and LC11T, isolated from a filtration substrate made from Japanese volcanic soil, was determined using a polyphasic approach. The strains grew at temperatures from 5 to 45 °C, on media of pH between 6 and 11 and in the presence of 7 % NaCl. The major menaquinone was MK-9(H4). The major fatty acid was iso-C16 : 0. A phylogenetic tree based on 16S rRNA gene sequences showed that the two strains formed a distinct evolutionary lineage within the genus Amycolatopsis. On the basis of their morphological, physiological and genotypic characteristics, the isolates are proposed to represent two novel species of the genus Amycolatopsis, for which the names Amycolatopsis echigonensis sp. nov. (type strain LC2T =IAM 15387T =CCTCC AB206019T), and Amycolatopsis niigatensis sp. nov. (type strain LC11T =IAM 15388T =CCTCC AB206020T) are proposed.

A novel facultatively methylotrophic, Gram-negative, rod-shaped bacterium, designated strain S2R03-9T, was isolated from jeotgal, a traditional Korean fermented seafood. The organism was strictly aerobic, motile by means of a single polar flagellum, non-sporulating and catalase- and oxidase-positive. Strain S2R03-9T grew in the presence of 0–1 % (w/v) NaCl and at pH 6.0–10.0, with optimum growth in the absence of NaCl and at pH 7.0. It grew at temperatures in the range 20.0–30.0 °C, with optimum growth at 30 °C. Colonies grown on R2A medium were non-pigmented, opaque and creamy white. Phylogenetic analysis based on 16S rRNA gene sequences indicated that it was most closely related to Methylobacterium organophilum JCM 2833T (96.6 % similarity) and the phylogenetic similarities to all other Methylobacterium species with validly published names were less than 95.0 %. The DNA G+C content was 64.9 mol%. The phylogenetic analysis, the phenotypic assessment and the chemotaxonomic data (major ubiquinone, Q-10; major fatty acids, C18 : 1 and C18 : 0) showed that S2R03-9T represents a novel species within the genus Methylobacterium in the class Alphaproteobacteria, for which the name Methylobacterium jeotgali sp. nov. is proposed. The type strain is S2R03-9T (=KCTC 12671T=LMG 23639T).
