List of new names and new combinations previously effectively, but not validly, published
The purpose of this announcement is to effect the valid publication of the following new names and new combinations under the procedure described in the Bacteriological Code (1990 Revision). Authors and other individuals wishing to have new names and/or combinations included in future lists should send three copies of the pertinent reprint or photocopies thereof, or an electronic copy of the published paper, to the IJSEM Editorial Office for confirmation that all of the other requirements for valid publication have been met. It is also a requirement of IJSEM and the ICSP that authors of new species, new subspecies and new combinations provide evidence that types are deposited in two recognized culture collections in two different countries (i.e. documents certifying deposition and availability of type strains). It should be noted that the date of valid publication of these new names and combinations is the date of publication of this list, not the date of the original publication of the names and combinations. The authors of the new names and combinations are as given below, and these authors' names will be included in the author index of the present issue and in the volume author index. Inclusion of a name on these lists validates the publication of the name and thereby makes it available in bacteriological nomenclature. The inclusion of a name on this list is not to be construed as taxonomic acceptance of the taxon to which the name is applied. Indeed, some of these names may, in time, be shown to be synonyms, or the organisms may be transferred to another genus, thus necessitating the creation of a new combination.

Notification that new names and new combinations have appeared in volume 57, part 4, of the IJSEM
This listing of names published in a previous issue of the IJSEM is provided as a service to bacteriology to assist in the recognition of new names and new combinations. This procedure was proposed by the Judicial Commission [Minute 11(ii), Int J Syst Bacteriol 41 (1991), p. 185]. The names given herein are listed according to the Rules of priority (i.e. page number and order of valid publication of names in the original articles). Taxonomic opinions included in this List (i.e. the creation of synonyms or the emendation of circumscriptions) cannot be considered as validly published nor, in any other way, approved by the International Committee on Systematics of Prokaryotes and its Judicial Commission.

Notification of changes in taxonomic opinion previously published outside the IJSEM
The Bacteriological Code deals with the nomenclature of prokaryotes. This may include existing names (the Approved Lists of Bacterial Names) as well as new names and new combinations. In this sense the Code is also dealing indirectly with taxonomic opinions. However, as with most codes of nomenclature there are no mechanisms for formally recording taxonomic opinions that do not involve the creation of new names or new combinations. In particular, it would be desirable for taxonomic opinions resulting from the creation of synonyms or emended descriptions to be made widely available to the public. In 2004, the Editorial Board of the International Journal of Systematic and Evolutionary Microbiology (IJSEM) agreed unanimously that it was desirable to cover such changes in taxonomic opinions (i.e. the creation of synonyms or the emendation of circumscriptions) previously published outside the IJSEM, and to introduce a List of Changes in Taxonomic Opinion [Notification of changes in taxonomic opinion previously published outside the IJSEM; Euzéby et al. (2004). Int J Syst Evol Microbiol 54, 1429–1430]. Scientists wishing to have changes in taxonomic opinion included in future lists should send one copy of the pertinent reprint or a photocopy or a PDF file thereof to the IJSEM Editorial Office or to the Lists Editor. It must be stressed that the date of proposed taxonomic changes is the date of the original publication not the date of publication of the list. Taxonomic opinions included in the List of Changes in Taxonomic Opinion cannot be considered as validly published nor, in any other way, approved by the International Committee on Systematics of Prokaryotes and its Judicial Commission. The names that are to be used are those that are the ‘correct names' (in the sense of Principle 6) in the opinion of the bacteriologist, with a given circumscription, position and rank. A particular name, circumscription, position and rank does not have to be adopted in all circumstances. Consequently, the List of Changes in Taxonomic Opinion must be considered as a service to bacteriology and it has no ‘official character’, other than providing a centralized point for registering/indexing such changes in a way that makes them easily accessible to the scientific community.

Marmoricola aequoreus sp. nov., a novel actinobacterium isolated from marine sediment
More LessA yellow-coloured, marine actinobacterium, designated SST-45T, was isolated from sandy sediment under the surface of a beach and taxonomically characterized by physiological, chemotaxonomic and phylogenetic methods. The cells of the isolate were Gram-positive, aerobic, non-sporulating, non-motile, spherical cells that occurred singly, in pairs, in clusters or as short chains. The isolate grew at 10–37 °C, an initial pH 5.1–12.1 and in the presence of 5 % (w/v) NaCl. The organism possessed ll-2,6-diaminopimelic acid as the diagnostic diamino acid in the cell wall, MK-8(H4) as the major menaquinone, a polar lipid profile including diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and an unknown phospholipid, C18 : 1 and C16 : 0 as the major fatty acids, and a DNA G+C content of 72.4 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that the organism was related to members of the genera Marmoricola and Nocardioides. The closest neighbours were Marmoricola aurantiacus DSM 12652T (97.0 % sequence similarity) and Nocardioides jensenii KCTC 9134T (96.7 %). The combination of morphological and chemotaxonomic characters supported the assignment of the isolate to the genus Marmoricola. However, the organism is clearly distinguished phenotypically from the single described species of this genus, Marmoricola aurantiacus. Based on the data obtained, the organism has been assigned as a novel species, for which the name Marmoricola aequoreus sp. nov. is proposed. The type strain is strain SST-45T (=JCM 13812T=NRRL B-24464T).

Georgenia ruanii sp. nov., a novel actinobacterium isolated from forest soil in Yunnan (China), and emended description of the genus Georgenia
A Gram-positive, motile, short-rod-shaped strain, designated YIM 004T, was isolated from a forest-soil sample collected from Lijiang, Yunnan Province, China, and was investigated using a polyphasic taxonomic approach. The isolate contained chemotaxonomic markers that corresponded to those of its phylogenetic neighbour, Georgenia muralis, i.e. it possessed peptidoglycan type A4α with lysine as the diagnostic cell-wall diamino acid, the predominant menaquinone was MK-8(H4) and the major fatty acid was ai-C15 : 0. The G+C content of the genomic DNA was 72.9 mol%. Strain YIM 004T exhibited a 16S rRNA gene sequence similarity of 97.3 % and a DNA–DNA relatedness value of 18 % with respect to G. muralis DSM 14418T. On the basis of the phenotypic and genotypic differences between the isolate and G. muralis, strain YIM 004T represents a novel species of the genus Georgenia, for which the name Georgenia ruanii sp. nov. is proposed. The type strain is YIM 004T (=CCTCC AB 204065T=DSM 17458T=KCTC 19029T). In addition, an emended description of the genus Georgenia is presented.

Alloscardovia omnicolens gen. nov., sp. nov., from human clinical samples
More LessThe taxonomic position of 12 isolates tentatively assigned to the genus Bifidobacterium on the basis of a limited phenotypic characterization was examined. The isolates were collected between 1978 and 2005 in Belgium, Sweden and Norway, and originated from various human clinical samples, including urine, blood, urethra, oral cavity, tonsil, and abscesses of lung and aortic valve. On the basis of band number and clustering analysis, repetitive DNA element-based PCR fingerprinting using the BOXA1R and (GTG)5 primers indicated that the clinical isolates represented a taxon probably not belonging to the genus Bifidobacterium. Analysis of 16S rRNA gene sequence similarities revealed that the isolates were most closely affiliated to Parascardovia denticolens LMG 18312T (93.0–93.2 %), Scardovia inopinata LMG 18313T (92.9–93.1 %) and other members of the Bifidobacteriaceae, indicating that the isolates belong to a novel genus within that family. This observation was further substantiated by the results of partial sequencing of the heat-shock protein 60 gene (hsp60) and determination of the DNA G+C contents (47.3–48.3 mol%). Members of the novel taxon can be phenotypically distinguished from S. inopinata, P. denticolens and Gardnerella vaginalis by the ability to grow on agar under aerobic conditions and on the basis of positive reactions for acid production from l-arabinose, raffinose, salicin and d-xylose. Unambiguous phenotypic differentiation from Aeriscardovia aeriphila and Bifidobacterium species may be difficult, so phenotypic analyses should be complemented by molecular methods. The values for DNA–DNA binding among four members of the novel genus were in the range of 89–100 %, indicating that the strains should be considered as a single novel species of a novel genus, for which the name Alloscardovia omnicolens gen. nov., sp. nov. is proposed. The type strain of Alloscardovia omnicolens is CCUG 31649T (=LMG 23792T).

Curtobacterium ammoniigenes sp. nov., an ammonia-producing bacterium isolated from plants inhabiting acidic swamps in actual acid sulfate soil areas of Vietnam
The ammonia-producing bacteria B55T, CA73, SA69 and SA72 were isolated from the waterweeds Ludwigia adscendens (B55T) and Eleocharis dulcis (CA73, SA69 and SA72) grown in highly acidic swamps (pH 2–4) in actual acid sulfate soil areas of Vietnam. The isolates were Gram-positive, irregular rod-shaped, non-spore-forming bacteria. On the basis of 16S rRNA gene sequence similarity, strain B55T was shown to belong to the genus Curtobacterium of the class Actinobacteria. Chemotaxonomic data (MK-9 as major isoprenoid quinone, d-ornithine as cell-wall diamino acid, acetyl as the acyl type of peptidoglycan) supported the affiliation of all four strains to this genus. Although their 16S rRNA gene sequence similarity was 99 % to species with validly published names within the genus, they formed a group that was distinct in the phylogenetic tree, and DNA–DNA relatedness values to these established species were less than 10 %. The results of physiological and biochemical tests and major fatty acids (cyclohexyl-C17 : 0, anteiso-C17 : 0 and cyclohexyl-C19 : 0) allowed phenotypic differentiation of these strains from the species of Curtobacterium with validly published names. Therefore, strains B55T, CA73, SA69 and SA72 represent a novel species, for which the name Curtobacterium ammoniigenes sp. nov. is proposed. The type strain is B55T (=NBRC 101786T=VTCC D6-11T=JCM 14609T).

Solirubrobacter soli sp. nov., isolated from soil of a ginseng field
More LessA Gram-positive, non-spore-forming, rod-shaped and non-motile bacterium, strain Gsoil 355T, was isolated from soil of a ginseng field in South Korea. In phylogenetic analyses based on 16S rRNA gene sequences, strain Gsoil 355T showed the highest levels of sequence similarity with respect to Solirubrobacter pauli B33D1T (97.4 %), Conexibacter woesei DSM 14684T (94.2 %) and Patulibacter minatonensis KV-614T (91.8 %). The strain possesses menaquinone MK-7(H4) and contains C16 : 0 and C18 : 0 ω9c as the predominant fatty acids. The DNA G+C content is 71.5 mol%. On the basis of genotypic and phenotypic characteristics, strain Gsoil 355T represents a novel species of the genus Solirubrobacter, for which the name Solirubrobacter soli sp. nov. is proposed. The type strain is Gsoil 355T (=KCTC 12628T=LMG 23485T).

Nocardia terpenica sp. nov., isolated from Japanese patients with nocardiosis
Two bacterial strains isolated from different hospitals in Japan were subjected to a polyphasic analysis. Strains IFM 0406 and IFM 0706T, producers of novel terpenoid antibiotics, were found to have morphological, biochemical, physiological and chemotaxonomic properties consistent with their classification in the genus Nocardia, except for the presence of MK-8(H4) as one of the predominant menaquinones in addition to the major menaquinone MK-8(H4ω-cyc). The 16S rRNA gene sequence similarity of strains IFM 0406 and IFM 0706T was 99.9 %, and the closest members of Nocardia to these strains were the type strains of Nocardia nova and Nocardia mexicana, showing similarity of 97.5 and 97.1 %, respectively. Based on their characteristic phenotypic and phylogenetic properties, a novel species of the genus Nocardia, Nocardia terpenica sp. nov. is proposed for the two strains. The type strain is IFM 0706T (=JCM 13033T=DSM 44935T=NBRC 100888T).

Tsukamurella spongiae sp. nov., a novel actinomycete isolated from a deep-water marine sponge
More LessA Gram-positive, rod-shaped, non-spore-forming bacterium (strain K362T) was isolated from a deep-water marine sponge collected off the coast of Curaçao in the Netherlands Antilles. On the basis of 16S rRNA gene sequence similarities, strain K362T was shown to belong to the genus Tsukamurella, being most closely related to Tsukamurella pulmonis (99.2 %), Tsukamurella tyrosinosolvens (98.9 %), Tsukamurella strandjordii (98.8 %), Tsukamurella pseudospumae (98.8 %) and Tsukamurella spumae (98.8 %). A combination of the substrate utilization patterns, the fatty acid and mycolic acid profiles and the DNA–DNA hybridization results supported the affiliation of strain K362T to the genus Tsukamurella and enabled the genotypic and phenotypic differentiation of strain K362T from the seven recognized Tsukamurella species. Strain K362T therefore represents a novel species of the genus Tsukamurella, for which the name Tsukamurella spongiae sp. nov. is proposed. The type strain is K362T (=DSM 44990T=NRRL B-24467T).

Nocardia coubleae sp. nov., isolated from oil-contaminated Kuwaiti soil
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).

Nonomuraea bangladeshensis sp. nov. and Nonomuraea coxensis sp. nov.
More LessTwo novel bacterial strains were isolated from sandy soil from Cox's Bazar, Bangladesh. Strains 5-10-10T and 5-38-42T were Gram-positive, aerobic, non-motile actinomycetes that form branched substrate and aerial mycelium. On the basis of 16S rRNA gene sequence similarity studies, the novel strains were shown to belong to the genus Nonomuraea, being most closely related to Nonomuraea fastidiosa. Chemotaxonomic data supported the assignment of the novel strains as members of the genus Nonomuraea. Strain 5-10-10T contained MK-9(H4) and strain 5-38-42T contained MK-9(H6) and MK-9(H4) as the major menaquinones. Major polar lipids were phosphatidylethanolamine and hydroxyphosphatidylethanolamine. The major cellular fatty acid for strain 5-10-10T was iso-C16 : 0 (26.4 %); C16 : 0 (17.4 %) was the major cellular fatty acid for strain 5-38-42T. The results of DNA–DNA hybridization and physiological tests enabled strains 5-10-10T and 5-38-42T to be differentiated genotypically and phenotypically from each other and from the closely related species, N. fastidiosa. On the basis of these results, strains 5-10-10T and 5-38-42T represent two novel species of the genus Nonomuraea. Following an evaluation of morphological, physiological and chemotaxonomic characteristics, 16S rRNA gene sequence comparisons and DNA–DNA hybridization experiments, the new isolates are proposed as two novel species, Nonomuraea bangladeshensis sp. nov. [type strain, 5-10-10T (=MTCC 8089T=JCM 13930T)] and Nonomuraea coxensis sp. nov. [type strain, 5-38-42T (=MTCC 8090T=JCM 13931T)].

Nocardia amamiensis sp. nov., isolated from a sugar-cane field in Japan
More LessAn actinomycete, strain TT 00-78T, was isolated from soil from a sugar-cane field on Amami Island in Japan, using an SDS/yeast extract pre-treatment method, and the taxonomy was studied using a polyphasic approach. The chemotaxonomic and morphological characterizations clearly demonstrated that the strain belongs to the genus Nocardia. 16S rRNA gene sequencing studies showed that the strain was closely related to the type strains of Nocardia pneumoniae (98.6 %), Nocardia araoensis (98.1 %), Nocardia arthritidis (97.9 %) and Nocardia beijingensis (97.7 %). However, the results of DNA–DNA hybridization and physiological and biochemical tests showed that strain TT 00-78T could be differentiated from its closest phylogenetic relatives both genotypically and phenotypically. Therefore this strain represents a novel species of the genus Nocardia, for which the name Nocardia amamiensis sp. nov. is proposed. The type strain is TT 00-78T (=NBRC 102102T=DSM 45066T=KCTC 19208T).

Streptomyces emeiensis sp. nov., a novel streptomycete from soil in China
More LessAn actinomycete, strain 4776T, was isolated from soil collected from Emei Mountain in Sichuan Province, China. The taxonomic status of this strain was established using a polyphasic approach. The organism was found to have morphological and chemotaxonomic characteristics typical of streptomycetes. Phylogenetic analysis based on the almost complete 16S rRNA gene sequence indicated that the novel isolate belongs to the genus Streptomyces and consistently falls into a clade together with Streptomyces prasinopilosus DSM 40098T, Streptomyces prasinus JCM 4603T, Streptomyces bambergiensis DSM 40590T, Streptomyces hirsutus DSM 40095T and Streptomyces cyanoalbus DSM 40198T. However, DNA–DNA relatedness and phenotypic data distinguished strain 4776T from these phylogenetically related type strains. It is therefore concluded that strain 4776T (=CGMCC 4.3504T=DSM 41884T) represents a novel species of the genus Streptomyces, for which the name Streptomyces emeienseis sp. nov. is proposed.

Amycolatopsis saalfeldensis sp. nov., a novel actinomycete isolated from a medieval alum slate mine
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).

Halopiger xanaduensis gen. nov., sp. nov., an extremely halophilic archaeon isolated from saline Lake Shangmatala in Inner Mongolia, China
Strain SH-6T was isolated from the sediment of Lake Shangmatala, a saline lake in Inner Mongolia (China). Cells were pleomorphic. The organism was neutrophilic and required at least 2.5 M (15 %) NaCl, but not MgCl2, for growth; optimal growth occurred at 4.3 M (25 %) NaCl. The G+C content of its DNA was 63.1 mol%. 16S rRNA gene sequence analysis revealed that strain SH-6T is a member of the family Halobacteriaceae, but there was a low level of similarity with other members of this family. Highest sequence similarity (94.6 %) was obtained with the 16S rRNA genes of the type strains of Natronolimnobius innermongolicus and Natronolimnobius baerhuensis. Polar lipid analyses revealed that strain SH-6T contains phosphatidylglycerol and phosphatidylglyceromethylphosphate, derived from both C20C20 and C20C25 glycerol diethers together with the glycolipid S2-DGD-1. On the basis of the data obtained, the new isolate could not be classified in any recognized genus. Strain SH-6T is thus considered to represent a novel species in a new genus within the family Halobacteriaceae, order Halobacteriales, for which the name Halopiger xanaduensis gen. nov., sp. nov. is proposed. The type strain of Halopiger xanaduensis is SH-6T (=CECT 7173T=CGMCC 1.6379T=JCM 14033T).

Acidianus sulfidivorans sp. nov., an extremely acidophilic, thermophilic archaeon isolated from a solfatara on Lihir Island, Papua New Guinea, and emendation of the genus description
More LessA novel, extremely thermoacidophilic, obligately chemolithotrophic archaeon (strain JP7T) was isolated from a solfatara on Lihir Island, Papua New Guinea. Cells of this organism were non-motile, Gram-negative staining, irregular-shaped cocci, 0.5–1.5 μm in size, that grew aerobically by oxidation of sulfur, Fe2+ or mineral sulfides. Cells grew anaerobically using Fe3+ as a terminal electron acceptor and H2S as an electron donor but did not oxidize hydrogen with elemental sulfur as electron acceptor. Strain JP7T grew optimally at 74 °C (temperature range 45–83 °C) and pH 0.8–1.4 (pH range 0.35–3.0). On the basis of 16S rRNA gene sequence similarity, strain JP7T was shown to belong to the Sulfolobaceae, being most closely related to the type strains of Acidianus ambivalens (93.7 %) and Acidianus infernus (93.6 %). Cell-membrane lipid structure, DNA base composition and 16S rRNA gene sequence similarity data support the placement of this strain in the genus Acidianus. Differences in aerobic and anaerobic metabolism, temperature and pH range for growth, and 16S rRNA gene sequence differentiate strain JP7T from recognized species of the genus Acidianus, and an emendation of the description of the genus is proposed. Strain JP7T is considered to represent a novel species of the genus Acidianus, for which the name Acidianus sulfidivorans sp. nov. is proposed. The type strain is JP7T (=DSM 18786T=JCM 13667T).

Haloterrigena hispanica sp. nov., an extremely halophilic archaeon from Fuente de Piedra, southern Spain
An extremely halophilic archaeon belonging to the order Halobacteriales was isolated from Fuente de Piedra salt lake, Spain. This strain, designated FP1T, was a pleomorphic coccoid, neutrophilic and required at least 15 % (w/v) NaCl for growth. Strain FP1T grew at 37–60 °C, with optimal growth at 50 °C. Mg2+ was not required, but growth was observed with up to 10 % (w/v) MgSO4. Polar lipid analysis revealed the presence of mannose-6-sulfate(1-2)-glucose glycerol diether as a major glycolipid. Both C20C20 and C20C25 core lipids were present. The genomic DNA G+C content was 62.0 mol%. Phylogenetic analysis based on comparison of 16S rRNA gene sequences demonstrated that the isolate was most closely related to species of the genus Haloterrigena. DNA–DNA reassociation values between strain FP1T and the most closely related species of the genus Haloterrigena (Haloterrigena thermotolerans, Haloterrigena saccharevitans and Haloterrigena limicola) were lower than 29 %. It is therefore considered that strain FP1T represents a novel species of the genus Haloterrigena, for which the name Haloterrigena hispanica sp. nov. is proposed. The type strain is FP1T (=DSM 18328T=ATCC BAA-1310T).

Thermococcus thioreducens sp. nov., a novel hyperthermophilic, obligately sulfur-reducing archaeon from a deep-sea hydrothermal vent
A hyperthermophilic, sulfur-reducing, organo-heterotrophic archaeon, strain OGL-20PT, was isolated from ‘black smoker’ chimney material from the Rainbow hydrothermal vent site on the Mid-Atlantic Ridge (36.2°N, 33.9°W). The cells of strain OGL-20PT have an irregular coccoid shape and are motile with a single flagellum. Growth was observed within a pH range of 5.0−8.5 (optimum pH 7.0), an NaCl concentration range of 1–5 % (w/v) (optimum 3 %) and a temperature range of 55–94 °C (optimum 83–85 °C). The novel isolate is strictly anaerobic and obligately dependent upon elemental sulfur as an electron acceptor, but it does not reduce sulfate, sulfite, thiosulfate, Fe(III) or nitrate. Proteolysis products (peptone, bacto-tryptone, Casamino acids and yeast extract) are utilized as substrates during sulfur reduction. Strain OGL-20PT is resistant to ampicillin, chloramphenicol, kanamycin and gentamicin, but sensitive to tetracycline and rifampicin. The G+C content of the DNA is 52.9 mol%. The 16S rRNA gene sequence analysis revealed that strain OGL-20PT is closely related to Thermococcus coalescens and related species, but no significant homology by DNA–DNA hybridization was observed between those species and the new isolate. On the basis of physiological and molecular properties of the new isolate, we conclude that strain OGL-20PT represents a new separate species within the genus Thermococcus, for which we propose the name Thermococcus thioreducens sp. nov. The type strain is OGL-20PT (=JCM 12859T=DSM 14981T=ATCC BAA-394T).

Chitinophaga ginsengisegetis sp. nov. and Chitinophaga ginsengisoli sp. nov., isolated from soil of a ginseng field in South Korea
Two novel strains belonging to the phylum Bacteroidetes [formerly the Cytophaga–Flexibacter–Bacteroides (CFB) group], designated Gsoil 040T and Gsoil 052T, were isolated from the soil of a ginseng field in Pocheon province, South Korea. A polyphasic approach was used to characterize the taxonomic position of the novel strains. Both strains were Gram-negative, aerobic, non-motile, non-spore-forming and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel isolates belong to the genus Chitinophaga but are clearly separated from the recognized species of this genus; gene sequence similarities between the novel isolates and type strains of recognized species ranged from 91.2 to 96.5 %. One exception was found; strain Gsoil 052T and the type strain of Chitinophaga filiformis had a gene sequence similarity of 99.6 % but had a DNA–DNA relatedness value of 38 %. Phenotypic and chemotaxonomic data (major menaquinone, MK-7; major fatty acids, iso-C15 : 0 and C16 : 1 ω5c; major hydroxy fatty acid, iso-C17 : 0 3-OH and major polyamine, homospermidine) supported the affiliation of both strains Gsoil 040T and Gsoil 052T to the genus Chitinophaga. The results of physiological and biochemical tests enabled the genotypic and phenotypic differentiation of the novel strains from the other recognized species of the genus Chitinophaga. Therefore, it is suggested that the new isolates represent two novel species, for which the names Chitinophaga ginsengisegetis sp. nov. [type strain Gsoil 040T (=KCTC 12654T=DSM 18108T)] and Chitinophaga ginsengisoli sp. nov. [type strain Gsoil 052T (=KCTC 12592T=DSM 18017T)] are proposed.
