Three strains of anaerobic, non-pigmented, Gram-negative bacilli isolated from various human clinical samples were characterized in terms of phenotypic and genotypic tests, including sequence analysis of 16S rRNA and rpoB genes. The strains were most closely related to the type strains of Prevotella marshii and Prevotella shahii on the basis of both 16S rRNA (89.8 and 89.0 % identity, respectively) and rpoB gene sequences (83.1 and 82.8 % identity, respectively). Phylogenetic analysis showed that the isolates constituted a robust homogeneous group distinct from known species in the genus Prevotella. The rrn skeleton (as determined by PFGE) and the DNA G+C content, determined to be 39.4 mol% for strain LBN 293T, distinguished the novel isolates from the type strains of P. marshii and P. shahii. The three strains were saccharolytic and produced acetic, lactic and succinic acids as major metabolic end products. Polyphasic investigations supported the proposal of a novel species, Prevotella nanceiensis sp. nov., with LBN 293T (=AIP 261.03T =CIP 108993T =CCUG 54409T) as the type strain.

Three strains of anaerobic Gram-negative bacilli isolated from human oral sites were subjected to a comprehensive range of phenotypic and genotypic tests and were found to comprise a homogeneous group. 16S rRNA gene sequence analysis revealed the strains to constitute a novel group within the genus Prevotella, most closely related to Prevotella oris and Prevotella salivae. A novel species, Prevotella maculosa sp. nov., is proposed to accommodate these strains. Prevotella maculosa is saccharolytic and produces acetic and succinic acids as end products of fermentation. The G+C content of the DNA of the type strain is 48 mol%. The type strain of Prevotella maculosa is W1609T (=DSM 19339T =CCUG 54766T).

Two anaerobic, non-spore-forming, non-motile, Gram-negative-staining bacteria, strains YIT 12060T and YIT 12061T, were isolated from human faeces. Cells of strain YIT 12060T were coccoid to rod-shaped with round ends, positive for catalase, negative for indole and oxidase production, produced succinic and acetic acids as end products of glucose metabolism in peptone/yeast extract/glucose medium and had a DNA G+C content of 55.2 mol%. The main respiratory quinones were MK-10 (40 %) and MK-11 (57 %). Fatty acid analysis demonstrated the presence of a high concentration of iso-C15 : 0 (56 %). Following 16S rRNA gene sequence analysis, this strain was found to be most closely related to species of the genus Alistipes, with 90.9–92.6 % gene sequence similarities to type strains of this species. Phylogenetic analysis and biochemical data supported the affiliation of strain YIT 12060T to the genus Alistipes of the family ‘Rikenellaceae’. Strain YIT 12060T therefore represents a novel species of the genus Alistipes for which the name Alistipes indistinctus sp. nov. is proposed; the type strain is YIT 12060T (=DSM 22520T=JCM 16068T). Cells of the other isolate, strain YIT 12061T, were pleomorphic rods that were asaccharolytic, catalase- and oxidase-negative, positive for gelatin hydrolysis and indole production, produced small amounts of succinic, acetic and iso-valeric acids as end products of metabolism in peptone/yeast extract medium and had a DNA G+C content of approximately 42.4 mol%. On the basis of 16S rRNA gene sequence similarity values, this strain was shown to belong to the family ‘Porphyromonadaceae’ and related to the type strains of Odoribacter splanchnicus (89.6 %) and Odoribacter denticanis (86.2 %); similarity values with strains of recognized species within the family ‘Porphyromonadaceae’ were less than 84 %. Biochemical data supported the affiliation of strain YIT 12061T to the genus Odoribacter. Strain YIT 12061T therefore represents a novel species for which the name Odoribacter laneus sp. nov. is proposed; the type strain is YIT 12061T (=DSM 22474T=JCM 16069T).

Seven strains of anaerobic Gram-positive cocci isolated from human oral sites were subjected to a comprehensive range of phenotypic and genotypic tests. 16S rRNA gene sequence analysis revealed that the strains constituted a homogeneous group that was distinct from species with validly published names, but related to Peptostreptococcus anaerobius. All oral strains tested belonged to this group, whereas all non-oral strains studied were confirmed as P. anaerobius. A novel species, Peptostreptococcus stomatis sp. nov., is proposed to accommodate these oral strains. P. stomatis is weakly saccharolytic and produces acetic, butyric, isobutyric, isovaleric and isocaproic acids as end products of fermentation. The type strain of P. stomatis is W2278T (=DSM 17678T=CCUG 51858T); the G+C content of the DNA of this strain is 36 mol%.

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.

Three strains of a hitherto unknown, Gram-negative, anaerobic coccus were isolated from human samples. At the phenotypic level, the isolates displayed all the characteristics of bacteria belonging to the genus Veillonella. Sequence analysis revealed that the three strains shared >99·5 % similarity in 16S rDNA sequence and >98·4 % similarity in dnaK sequence. The three unknown strains formed a separate subclade that was clearly remote from Veillonella species of human and animal origin. Based on these results, the three strains were considered to represent a novel species within the genus Veillonella, for which the name Veillonella montpellierensis is proposed. The type strain of the species is ADV 281.99T (=CIP 107992T=CCUG 48299T).

A novel, Gram-negative, non-spore-forming, pleomorphic yellow-orange bacterial strain was isolated from a stadium seat. Strain CoronadoTfalls within theErythrobacteraceaefamily and the genusPorphyrobacterbased on 16S rRNA phylogenetic analysis. This strain has Q-10 as the predominant respiratory lipoquinone, as do other members of the family. The fatty acid profile of this strain is similar to otherPorphyrobacter, however CoronadoTcontains predominately C18:1ω7cis and C16:0, a high percentage of the latter not being observed in any otherErythrobacteraceae. This strain is catalase-positive and oxidase-negative, can grow from 4 to 28 °C, at NaCl concentrations 0.1–1.5%, and at pH 6.0–8.0. On the basis of phenotypic and phylogenetic data presented in this study, strain CoronadoTrepresents a novel species in thePorphyrobactergenus for which the namePorphyrobacter mercurialissp. nov. is proposed; the type strain is CoronadoT(=DSMZ 29971, =LMG 28700).

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.

Six isolates recovered from coffee seeds giving off a potato-like flavour were studied. Gene sequencing (rrs and rpoB) showed they belong to the genus Pantoea . By DNA–DNA hybridization, the isolates constituted a genomic species with less than 17 % relatedness to 96 strains representing enterobacterial species. Multilocus sequence analysis (gyrB, rpoB, atpD and infB genes) showed the isolates to represent a discrete species of the genus Pantoea . Nutritional versatility of the novel species was poor. The novel species is proposed as Pantoea coffeiphila sp.nov. and its type strain is Ca04T ( = CIP 110718T = DSM 28482T).

A micro-organism, DCY12T, comprising Gram-negative, non-motile, pale-yellow rods was isolated from soil from a ginseng field in South Korea and was investigated to determine its taxonomic status. It grew optimally at 30 °C and at pH 7.0, the G+C content of its DNA was 40.5 mol%, the major components of the fatty acid profile were C16 : 0 and C18 : 1 and the major ubiquinone was Q-8. A phylogenetic analysis based on the 16S rRNA gene sequence revealed that the novel isolate was most closely related to Hydrocarboniphaga effusa AP103T (89.2 %), Nevskia ramosa Soe1 (88.8 %) and Pseudomonas aeruginosa ATCC 10145T (83.2 %). The phenotypic, physiological, metabolic and phylogenetic properties of DCY12T suggest that it represents a novel genus (class Gammaproteobacteria) and species, for which the name Solimonas soli gen. nov., sp. nov. is proposed. The type strain of Solimonas soli is DCY12T (=KCTC 12834T =LMG 24014T).

A polyphasic analysis was undertaken of seven independent isolates of Gram-negative cocci collected from pathological clinical samples from New York, Louisiana, Florida and Illinois and healthy subgingival plaque from a patient in Virginia, USA. The 16S rRNA gene sequence similarity among these isolates was 99.7–100 %, and the closest species with a validly published name was Neisseria lactamica (96.9 % similarity to the type strain). DNA–DNA hybridization confirmed that these isolates are of the same species and are distinct from their nearest phylogenetic neighbour, N. lactamica . Phylogenetic analysis of 16S and 23S rRNA gene sequences indicated that the novel species belongs in the genus Neisseria . The predominant cellular fatty acids were C16 : 0, summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) and C18 : 1ω7c. The cellular fatty acid profile, together with other phenotypic characters, further supports the inclusion of the novel species in the genus Neisseria . The name Neisseria oralis sp. nov. (type strain 6332T  = DSM 25276T  = LMG 26725T) is proposed.
