Achromobacter animicus sp. nov., Achromobacter mucicolens sp. nov., Achromobacter pulmonis sp. nov. and Achromobacter spiritinus sp. nov., from human clinical samples

The phenotypic and genotypic characteristics of fourteen human clinical Achromobacter strains representing four genogroups which were delineated by sequence analysis of nusA, eno, rpoB, gltB, lepA, nuoL and nrdA loci, demonstrated that they represent four novel Achromobacter species. The present study also characterized and provided two additional reference strains for Achromobacter ruhlandii and Achromobacter marplatensis, species for which, thus far, only single strains are publicly available, and further validated the use of 2.1% concatenated nusA, eno, rpoB, gltB, lepA, nuoL and nrdA sequence divergence as a threshold value for species delineation in this genus. Finally, although most Achromobacter species can be distinguished by biochemical characteristics, the present study also highlighted considerable phenotypic intraspecies variability and demonstrated that the type strains may be phenotypically poor representatives of the species. We propose to classify the fourteen human clinical strains as Achromobacter mucicolens sp. nov. (with strain LMG 26685^T [=CCUG 61961^T] as the type strain), Achromobacter animicus sp. nov. (with strain LMG 26690^T [=CCUG 61966^T] as the type strain), Achromobacter spiritinus sp. nov. (with strain LMG 26692^T [=CCUG 61968^T] as the type strain), and Achromobacter pulmonis sp. nov. (with strain LMG 26696^T [=CCUG 61972^T] as the type strain).     

Meiothermus granaticius sp. nov., a new slightly thermophilic red-pigmented species from the Azores

Two red-pigmented isolates, with optimum growth temperatures between 45 and 50 °C, were recovered from a hot spring in the Furnas, Área da Fonte 1825 on the Island of São Miguel in the Azores. Phylogenetic analysis of the 16S rRNA gene sequences showed that these organisms represented a new species of the genus Meiothermus. These new isolates could be distinguished from other strains of the species of the genus Meiothermus primarily by the fatty acid composition and polar lipid pattern, since they did not possess 2-OH fatty acids or glycolipid variant GL-1a. Moreover, the two new isolates had the lowest growth temperature range of any of the known species of the genus Meiothermus. On the basis of the results presented here we propose the name Meiothermus granaticius for the new species represented by strains AF-68^T (=DSM 23260^T = LMG 25524^T) and AF-49 (=DSM 23259 = LMG 25525).     

Arcobacter molluscorum sp. nov., a new species isolated from shellfish

Nineteen bacteria isolates recovered from shellfish samples (mussels and oysters) showed a new and specific 16S rDNA-RFLP pattern with an Arcobacter identification method designed to recognize all species described up to 2008. These results suggested that they could belong to a new species. ERIC-PCR revealed that the 19 isolates belonged to 3 different strains. The sequence of the 16S rRNA gene of a representative strain (F98-3^T) showed 97.6% similarity with the closest species Arcobacter marinus followed by Arcobacter halophilus (95.6%) and Arcobacter mytili (94.7%). The phylogenetic analysis with the16S rRNA, rpoB, gyrB and hsp60 genes placed the shellfish strains within the same cluster as the three species mentioned (also isolated from saline habitats) but they formed an independent phylogenetic line. The DDH results between strain F98-3^T and A. marinus (54.8% ± 1.05), confirmed that it represents a new species. Several biochemical tests differentiated the shellfish isolates from all other Arcobacter species. Although the new species was different from A. mytili, they shared not only the same habitat (mussels) but also the characteristic of being so far the only Arcobacter species that are simultaneously negative for urea and indoxyl acetate hydrolysis. All results supported the classification of the shellfish strains as a new species, for which the name Arcobacter molluscorum sp. nov. with the type strain F98-3^T is proposed (=CECT 7696^T = LMG 25693^T).     

Classification of Achromobacter genogroups 2, 5, 7 and 14 as Achromobacter insuavis sp. nov., Achromobacter aegrifaciens sp. nov., Achromobacter anxifer sp. nov. and Achromobacter dolens sp. nov., respectively

The phenotypic and genotypic characteristics of seventeen Achromobacter strains representing MLST genogroups 2, 5, 7 and 14 were examined. Although genogroup 2 and 14 strains shared a DNA–DNA hybridization level of about 70%, the type strains of both genogroups differed in numerous biochemical characteristics and all genogroup 2 and 14 strains could by distinguished by nitrite reduction, denitrification and growth on acetamide. Given the MLST sequence divergence which identified genogroups 2 and 14 as clearly distinct populations, the availability of nrdA sequence analysis as a single locus identification tool for all Achromobacter species and genogroups, and the differential phenotypic characteristics, we propose to formally classify Achromobacter genogroups 2, 5, 7 and 14 as four novel Achromobacter species for which we propose the names Achromobacter insuavis sp. nov. (with strain LMG 26845^T [= CCUG 62426^T] as the type strain), Achromobacter aegrifaciens sp. nov. (with strain LMG 26852^T [= CCUG 62438^T] as the type strain), Achromobacter anxifer sp. nov. (with strain LMG 26857^T [= CCUG 62444^T] as the type strain), and Achromobacter dolens sp. nov. (with strain LMG 26840^T [= CCUG 62421^T] as the type strain).     

Mycoplasma feriruminatoris sp. nov., a fast growing Mycoplasma species isolated from wild Caprinae

Five Mycoplasma strains from wild Caprinae were analyzed: four from Alpine ibex (Capra ibex) which died at the Berlin Zoo between 1993 and 1994, one from a Rocky Mountain goat collected in the USA prior to 1987. These five strains represented a population different from the populations belonging to the ‘Mycoplasma mycoides cluster’ as tested using multi locus sequence typing, Matrix-assisted laser desorption/ionization time of flight mass spectrometry analysis and DNA–DNA hybridization. Analysis of the 16S rRNA gene (rrs), genomic sequence based in silico as well as laboratory DNA–DNA hybridization, and the analysis of phenotypic traits in particular their exceptionally rapid growth all confirmed that they do not belong to any Mycoplasma species described to date. We therefore suggest these strains represent a novel species, for which we propose the name Mycoplasma feriruminatoris sp. nov. The type strain is G5847^T (= DSM 26019^T = NCTC 1362^T).     

Larsenia salina gen. nov., sp. nov., a new member of the family Halomonadaceae based on multilocus sequence analysis

Two Gram-staining-negative, moderately halophilic bacteria, strains M1-18^T and L1-16, were isolated from a saltern located in Huelva (Spain). They were motile, strictly aerobic rods, growing in the presence of 3–25% (w/v) NaCl (optimal growth at 7.5–10% [w/v] NaCl), between pH 4.0 and 9.0 (optimal at pH 6.0–7.0) and at temperatures between 15 and 40 °C (optimal at 37 °C). Phylogenetic analysis based on 16S rRNA gene sequence comparison showed that both strains showed the higher similarity values with Chromohalobacter israelensis ATCC 43985^T (95.2–94.8%) and Chromohalobacter salexigens DSM 3043^T (95.0–94.9%), and similarity values lower than 94.6% with other species of the genera Chromohalobacter, Kushneria, Cobetia or Halomonas. Multilocus sequence analysis (MLSA) based on the partial sequences of atpA, rpoD and secA housekeeping genes indicated that the new isolates formed an independent and monophyletic branch that was related to the peripheral genera of the family Halomonadaceae, Halotalea, Carnimonas and Zymobacter, supporting their placement as a new genus of the Halomonadaceae. The DNA–DNA hybridization between both strains was 82%, whereas the values between strain M1-18^T and the most closely related species of Chromohalobacter and Kushneria were equal or lower to 48%. The major cellular fatty acids were C_18:1ω7c/C_18:1ω6c, C_16:0, and C_16:1ω7c/C_16:1ω6c, a profile that differentiate this new taxon from species of the related genera. We propose the placement of both strains as a novel genus and species, within the family Halomonadaceae, with the name Larsenia salina gen. nov., sp. nov. The type strain is M1-18^T (= CCM 8464 = CECT 8192^T = IBRC-M 10767^T = LMG 27461^T).     

Meiothermus rufus sp. nov., a new slightly thermophilic red-pigmented species and emended description of the genus Meiothermus

Four red-pigmented isolates, with optimum growth temperatures of approximately 55–60 °C and an optimum pH for growth between 7.5 and 8.5, were recovered from hot springs in Central France. Phylogenetic analysis of the 16S rRNA gene sequences showed that these organisms represented a new species of the genus Meiothermus. The new isolates could be distinguished from other strains of the species of the genus Meiothermus primarily by the glycolipid profile and fatty acid composition because these organisms lacked the hydroxy fatty acids and the glycolipid variant GL-1a found in all other isolates of the species of Meiothermus examined. On the basis of the results presented here we propose the name Meiothermus rufus for the new species, which is represented by strains CAL-4^T (=DSM 22234^T=LMG 24878^T) and CAL-12 (=DSM 22235=LMG 24879). We also propose emending the genus Meiothermus to include strains that have only one glycolipid instead of two glycolipid variants.     

Pseudomonas asturiensis sp. nov., isolated from soybean and weeds

Five strains of gram negative bacteria, isolated from soybean (LPPA 221^T, 222 and 223) and weeds (LPPA 816 and 1442), were analyzed by a polyphasic approach. The isolates showed variation in their phenotypic traits and were placed in the Pseudomonas fluorescens lineage, based on 16S rRNA gene sequence phylogeny, as a single but well separated cluster. MLSA analysis based on gyrB and rpoD sequences clustered the strains in a single branch in the Pseudomonas syringae group, and revealed P. viridiflava as closest relative. DNA–DNA hybridizations showed medium levels of DNA–DNA relatedness with the type strain of P. viridiflava (50%) and lower levels (<32%) with other type strains of the P. syringae group, supporting classification within a novel species of the genus Pseudomonas. The strains can be distinguished from species of the P. syringae group by the fatty acid C_17:0 cyclo that is present in a low amount (2.5%) and from P. viridiflava by their inability to assimilate d-tartrate and d-sorbitol, and by the formation of red colonies on TTC medium. For this new species, the name Pseudomonas asturiensis sp. nov. is proposed. The type strain is LPPA 221^T (=LMG 26898^T = CECT 8095^T).     

Proposal of Ensifer psoraleae sp. nov., Ensifer sesbaniae sp. nov., Ensifer morelense comb. nov. and Ensifer americanum comb. nov

In a survey of rhizobia associated with the native legumes in Yunnan Province, China, seven and nine strains isolated from the root nodules of Psoralea corylifolia, Sesbania cannabina and Medicago lupulina were respectively classified into the novel genomic species groups I and II in the genus Ensifer (former Sinorhizobium) based on the sequence analyses of the 16S rRNA gene. Analyses of concatenated housekeeping genes (atpD, recA and glnII) further revealed that they were distinct lineages in the genus, and group I was most similar to Ensifer terangae and Ensifer garamanticus (both with 94.2% similarity), while group II was most similar to Ensifer adhaerens (94.0%). These groups could be distinguished from closely related species by DNA–DNA relatedness, MALID-TOF MS, cellular fatty acid profiles and a series of phenotypic characters. Therefore, two novel species were proposed: Ensifer psoraleae sp. nov. (seven strains, type strain CCBAU 65732^T = LMG 26835^T = HAMBI 3286^T) and Ensifer sesbaniae sp. nov. (nine strains, type strain CCBAU 65729^T = LMG 26833^T = HAMBI 3287^T). They had a DNA G + C mol% (T_m) of 58.9 and 60.4, respectively. Both of the type strains formed effective nodules on common bean (Phaseolus vulgaris) and their hosts of origin. In addition, the previously described species Sinorhizobium morelense and Sinorhizobium americanum were renamed as Ensifer morelense comb. nov. and Ensifer americanum comb. nov. according to the accumulated data from different studies.     

Tepidamorphus gemmatus gen. nov., sp. nov., a slightly thermophilic member of the Alphaproteobacteria

Two isolates, with an optimum growth temperature of about 45–50 °C and an optimum pH for growth between 7.5 and 8.5, were recovered from a hot spring in the Furnas area on the Island of São Miguel in the Azores. Strains form irregular rod-shaped cells are motile and stain Gram negative. The cells multiply by budding. These strains are non-pigmented, strictly aerobic, catalase and oxidase positive. These organisms assimilated carbohydrates, organic acids and amino acids. The major fatty acids are 19:0_{cyclo ω8c} and 18:0. Ubiquinone 10 is the major respiratory quinone. The major polar lipids are diphosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine in addition to one unidentified aminolipid and one unidentified glycolipid. Bacteriochlorophyll a, puf genes and RuBisCo genes were not detected. Analysis of the 16S rRNA gene shows the strains to cluster with species of the genera Afifella, Rhodobium, Anderseniella and Amorphus to which they have sequence similarity in the range 93–94%. Based on 16S rRNA gene sequence analysis, physiological and biochemical characteristics we describe a new species of a novel genus represented by strain CB-27A^T (=DSM 19345^T=LMG 24113^T) for which we propose the name Tepidamorphus gemmatus.     

Chryseobacterium oncorhynchi sp. nov., isolated from rainbow trout (Oncorhynchus mykiss)

Genotypic and phenotypic analyses were performed on five Gram-negative, catalase and oxidase-positive, rod-shaped bacteria isolated from the gill and liver of four rainbow trout. Studies based on comparative 16S rRNA gene sequence analysis showed that the five new isolates shared 99.8-100% sequence similarity and that they belong to the genus Chryseobacterium. The nearest phylogenetic neighbours of the strain 701B-08(T) were Chryseobacterium ureilyticum F-Fue-04IIIaaaa(T) (99.1% 16S rRNA gene sequence similarity) and Chryseobacterium joosteii LMG 18212(T) (98.6%). DNA-DNA hybridization values between the five isolates were 91-99% and ranged from 2 to 53% between strain 701B-08(T) and the type strains of phylogenetically closely related species of Chryseobacterium. Strain 701B-08(T) had a DNA G+C content of 36.3 mol%, the major fatty acids were iso-C(15:0), iso-C(17:1)ω9c, C(16:1)ω6c and iso-C(17:0) 3-OH and the predominant respiratory quinone was MK-6. The novel isolates were distinguished from related Chryseobacterium species by physiological and biochemical tests. The genotypic and phenotypic properties of the isolates from rainbow trout suggest their classification as representatives of a novel species of the genus Chryseobacterium, for which the name Chryseobacterium oncorhynchi sp. nov. is proposed. The type strain is 701B-08(T) (=CECT 7794(T)=CCUG 60105(T)).     

Geodermatophilus tzadiensis sp. nov., a UV radiation-resistant bacterium isolated from sand of the Saharan desert

Three novel Gram-positive, aerobic, actinobacterial strains, CF5/2^T, CF5/1 and CF7/1, were isolated in 2007 during environmental screening of arid desert soil in the Sahara desert, Chad. Results from riboprinting, MALDI-TOF protein spectra and 16S rRNA sequence analysis confirmed that all three strains belonged to the same species. Phylogenetic analysis of 16S rRNA sequences with the strains’ closest relatives indicated that they represented a distinct species. The three novel strains also shared a number of physiological and biochemical characteristics distinct from previously named Geodermatophilus species. The novel strains’ peptidoglycan contained meso-diaminopimelic acid; their main phospholipids were phosphatidylcholine, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol and a small amount of phosphatidylglycerol; MK-9(H₄) was the dominant menaquinone. The major cellular fatty acids were the branched-chain saturated acids iso-C_16:0 and iso-C_15:0. Galactose was detected as diagnostic sugar. Based on these chemotaxonomic results, 16S rRNA gene sequence analysis and DNA–DNA hybridization between strain CF5/2^T and the type strains of Geodermatophilus saharensis, Geodermatophilus arenarius, Geodermatophilus nigrescens, Geodermatophilus telluris and Geodermatophilus siccatus, the isolates CF5/2^T, CF5/1 and CF7/1 are proposed to represent a novel species, Geodermatophilus tzadiensis, with type strain CF5/2^T = DSM 45416 = MTCC 11411 and two reference strains, CF5/1 (DSM 45415) and CF7/1 (DSM 45420).     

Pseudoscardovia suis gen. nov., sp. nov., a new member of the family Bifidobacteriaceae isolated from the digestive tract of wild pigs (Sus scrofa)

Seventeen fructose-6-phosphate phosphoketolase-positive bacterial strains were isolated from the digestive tract of wild pigs (Sus scrofa). Most of them were identified as Bifidobacterium boum according to sequences of 16S rRNA gene. Two strains isolated from the small intestine content had unusual morphology of cells in comparison with bifidobacteria. Cells growing in liquid anaerobic media were regular shaped rods arranged mostly in pairs. These isolates showed relatively low 16S rRNA gene sequence similarities (maximum identity of 94%) to members of the family Bifidobacteriaceae. Nevertheless, phylogenetic analyses of 16S rRNA, hsp60 and xfp gene sequences revealed that these strains are more related to recently described Neoscardovia, Aeriscardovia and other scardovial genera, than to Bifidobacterium species. Partial gene sequences of other phylogenetic markers showed low (65.8–89.5%) similarities to genome sequences of bifidobacteria and Gardnerella vaginalis. The major fatty acids detected in cells of the representative strain DPTE4^T were C_16:0, C_18:1, C_14:0. The peptidoglycan type of the DPTE4^T strain was A3β l-Orn(l-Lys)-l-Ser(l-Ala)-l-Ala₂. Polar lipid analysis revealed two phosphoglycolipids and phospholipids, a glycolipid and diphosphatidylglycerol. The results of phylogenetic, genotypic and phenotypic analyses support the proposal of a novel taxa, Pseudoscardovia suis gen. nov., sp. nov. (type strain = DPTE4^T = DSM 24744^T = CCM 7942^T).     

Didymella pisi sp. nov., the teleomorph of Ascochyta pisi

The anamorphic pycnidial fungus Ascochyta pisi is one member of a species complex that causes Ascochyta blight of pea, a potentially devastating disease. The teleomorphic state of this fungus was induced under laboratory conditions. Using morphological and molecular characters, we placed the teleomorph within the genus Didymella as D. pisi and describe a heterothallic mating system using a PCR-based mating type assay and in vitro crosses. We compare D. pisi with other Didymella spp. with which it might be confused.     

Gibbsiella greigii sp. nov., a novel species associated with oak decline in the USA

In 2010, cream-coloured, Gram-negative staining, facultatively anaerobic enterobacteria were isolated from a single black oak tree (Quercus kelloggii) exhibiting decline symptoms in southern California, USA. These 12 isolates were tentatively identified as Gibbsiella quercinecans based on partial gyrB sequencing. Closer examination of the strains using multilocus sequence analysis, based on partial sequences of gyrB, rpoB, infB and atpD genes, and almost complete 16S rRNA gene sequencing suggested that the isolates belong to a novel taxon within the genus Gibbsiella with G. quercinecans as their closest phylogenetic relative. DNA–DNA relatedness studies confirmed that the strains belong to a single taxon in Gibbsiella, which can be differentiated from other members of the genus by several phenotypic traits. Therefore, the name Gibbsiella greigii sp. nov. is proposed for this novel species isolated from symptomatic Q. kelloggii in the USA with FRB 224^T (=LMG 27716^T = NCPPB 4583^T) as the type strain.     

Heavy metal tolerant Metalliresistens boonkerdii gen. nov., sp. nov., a new genus in the family Bradyrhizobiaceae isolated from soil in Thailand

Bacterial strains from inoculated soybean field soil in Thailand were directly isolated using Bradyrhizobium japonicum selective medium (BJSM), on the basis of Zn²⁺ and Co²⁺ resistance of B. japonicum and B. elkanii. The isolates were classified into symbiotic and non-symbiotic groups by inoculation assays and Southern hybridization of nod and nif genes. In this study, a nearly full-length 16S rRNA gene sequence showed that the non-symbiotic isolates were more closely related to members of Rhodopseudomonas and to a number of uncultured bacterial clones than to members of Bradyrhizobium. Therefore, a polyphasic study was performed to determine the taxonomic positions of four representatives of the non-symbiotic isolates. Multilocus phylogenetic analysis of individual genes and a combination of the 16S rRNA and three housekeeping genes (atpD, recA and glnII) supported the placement of the non-symbiotic isolates in a different genus. The ability of heavy metal resistance in conjunction with phenotypic analyses, including cellular fatty acid content and biochemical characteristics, showed that the non-symbiotic isolates were differentiated from the other related genera in the family Bradyrhizobiaceae. Therefore, the non-symbiotic isolates represented a novel genus and species, for which the name Metalliresistens boonkerdii gen. nov., sp. nov. is proposed. The type strain is NS23 (= NBRC 106595^T = BCC 40155^T).     

Hymenobacter perfusus sp. nov., Hymenobacter flocculans sp. nov. and Hymenobacter metalli sp. nov. three new species isolated from an uranium mine waste water treatment system

Three red-pink pigmented strains, designated A1-12(T), A2-50A(T) and A2-91(T), were recovered from two different sites in a uranium mine. For all strains, the optimum growth temperature was 25°C, the optimum pH was 6.0-6.5 and the DNA G+C contents were between 60 and 63.4 mol%. The major respiratory quinone was menaquinone 7 (MK-7) and the fatty acid profiles contained iso- and anteiso-branched C15 fatty acids, summed feature 3 (16:1 ω6c and/or ω7c and/or 15:0 iso 2-OH), summed feature 4 (17:1 anteiso B and/or iso I) and the unsaturated fatty acid 16:1 ω5c as the major components. Phylogenetic analysis of the 16S rRNA gene sequences showed that these organisms represented three distinct branches within the family Flexibacteraceae most closely related to the members of the genus Hymenobacter. Strain A1-12(T) formed a distinct phylogenetic line along with H. rigui KCTC 12533(T) and they shared approximately 98.9% 16S rRNA gene sequence similarity. However, these two strains shared only 14.7% pairwise similarity in their genomic DNA. Strains A2-50A(T) and A2-91(T) formed two distinct lineages, related to the species H. soli KCTC 12607(T), sharing about 95.5% 16S rRNA gene sequence similarity between themselves, and 88.3 and 92.0% with other members of the genus Hymenobacter. Based on the phylogenetic analysis and physiological and biochemical characteristics, these isolates were considered to represent three novel species for which we propose the names Hymenobacter perfusus for strain A1-12(T) (=CIP 110166=LMG 26000), Hymenobacter flocculans for strain A2-50A(T) (=CIP 110139=LMG 25699) and Hymenobacter metalli for strain A2-91(T) (=CIP 110140=LMG 25700).     

Arcobacter bivalviorum sp. nov. and Arcobacter venerupis sp. nov., new species isolated from shellfish

A group of ten Arcobacter isolates (Gram negative, slightly curved motile rods, oxidase positive) was recovered from mussels (nine) and from clams (one). These isolates could not be assigned to any known species using the molecular identification methods specific for this genus (16S rDNA-RFLP and m-PCR). The aim of this study is to establish the taxonomic position of these isolates. The 16S rRNA gene sequence similarity of mussel strain F4(T) to the type strains of all other Arcobacter species ranged from 91.1% to 94.8%. The species most similar to the clams' strain F67-11(T) were Arcobacter defluvii (CECT 7697(T), 97.1%) and Arcobacter ellisii (CECT 7837(T), 97.0%). On the basis of phylogenetic analyses with 16S rRNA, rpoB, gyrB and hsp60 genes, the mussel and clam strains formed two different, new lineages within the genus Arcobacter. These data, together with their different phenotypic characteristics and MALDI-TOF mass spectra, revealed that these strains represent two new species, for which the names Arcobacter bivalviorum (type strain F4(T)=CECT 7835(T)=LMG 26154(T)) and Arcobacter venerupis (type strain F67-11(T)=CECT 7836(T)=LMG 26156(T)) are proposed.     

Seminibacterium arietis gen. nov., sp. nov., isolated from the semen of rams

Two gram-negative, catalase- and oxidase-positive, bacillus-shaped bacterial strains were isolated from the semen of two rams. 16S rRNA gene sequencing demonstrated that both isolates represented a distinct subline within the family Pasteurellaceae with <95% sequence similarity to any recognized member of this family. Sequencing of rpoB and infB genes confirmed this finding with the semen isolates representing a new sub-line within the family Pasteurellaceae. The main cell fatty acids of strain DICM-00342^T were C_14:0, C_16:0, C_18:1ω7c and summed feature 3 (C_16:1ω7c/iso-C_15:0 2OH). Ubiquinone Q-8 was the major quinone and 1,3-diaminopropane was the predominat polyamine. Major polar lipids were phosphatidylglycerol and phosphatidylethanolamine. The new genus can be phenotypically distinguished from currently described genera of this family based on physiological traits and a combination of signature amino acids in the RpoB protein sequence. On the basis of these results we describe a new genus and species for which we propose the name of Seminibacterium arietis gen. nov., sp. nov. (DICM11-00342^T = CCUG 61707^T = CECT 8033^T).
