<Emphasis Type="Italic">Rhizobium sphaerophysae</Emphasis> sp. nov., a novel species isolated from root nodules of <Emphasis Type="Italic">Sphaerophysa salsula</Emphasis> in China

Four gram-negative, aerobic, motile, non-spore, forming rods with a wide pH and temperature range for growth (pH 7.0–11.0, optimum pH 8.0; 20–45°C, optimum 28°C) strains were isolated from root nodules of Sphaerophysa salsula and characterized by means of a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the four strains formed a new lineage related to the genus Rhizobium and the sequence similarities between the isolate and the most related type strain Rhizobium giardinii was 96.5%. These strains also formed a distinctive group from the reference strains for defined Rhizobium species based on housekeeping gene sequences (atpD and recA), BOX-PCR fingerprinting, phenotypic features and symbiotic properties. The representative strain CCNWGS0238^T has DNA-DNA relatedness of less than 33.4% with the most closely related species R. giardinii. It is therefore proposed as a new species, Rhizobium sphaerophysae sp. nov., with isolate CCNWGS0238^T (=ACCC17498^T = HAMBI3074^T) as the type strain.     

<Emphasis Type="Italic">Ogataea phyllophila</Emphasis> sp. nov., <Emphasis Type="Italic">Candida chumphonensis</Emphasis> sp. nov. and <Emphasis Type="Italic">Candida mattranensis</Emphasis> sp. nov., three methylotrophic yeast species from phylloplane in Thailand

Five strains (LN12, LN14^T, LN15^T, LN16 and LN17^T) representing three novel methylotrophic yeast species were isolated from the external surface of plant leaves by three-consecutive enrichments. On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics, the sequence analysis of the D1/D2 domain of the large subunit (LSU) rRNA gene and the phylogenetic analysis, the five strains were assigned to be one novel Ogataea species and two novel Candida species. Three strains (LN12, LN14^T and LN16) represent a single novel species of the genus Ogataea, for which the name Ogataea phyllophila sp. nov. is proposed. The type strain is LN14^T (= BCC 42666^T = NBRC 107780^T = CBS 12095^T). Strain LN15^T was assigned to be Candida chumphonensis sp. nov. (type strain LN15^T = BCC 42667^T = NBRC 107781^T = CBS 12096^T). Strain LN17^T represented another novel species of Candida that was named Candida mattranensis sp. nov. (type strain LN17^T = BCC 42668^T = NBRC 107782^T = CBS 12097^T).     

<Emphasis Type="Italic">Sphingomonas jejuensis</Emphasis> sp. nov., isolated from marine sponge <Emphasis Type="Italic">Hymeniacidon flavia</Emphasis>

A Gram-negative, non-motile, rod shaped, and orange-pigmented chemoheterotrophic bacterium, strain MS-31^T was isolated from the marine sponge Hymeniacidon flavia, collected from near Jeju Island, Korea. The Strain MS-31^T was subjected to a polyphasic taxonomic study. The phylogenetic analysis based on the 16S rRNA gene sequences revealed that the novel isolate could be affiliated within the genus Sphingomonas. The strain MS-31^T showed 95.6% of 16S rRNA gene sequence similarity with the most closely related species Sphingomonas koreensis JSS26^T. The DNA G+C content of the strain MS-31^T was 69.4 mol%. The major isoprenoid quinone was ubiqunone 10 and predominant cellular fatty acids were summed feature 7 (comprising C_18:1 ω7c, C_18:1 Ω9t and/or C_18:1 ωl2t, 39.7%), C_16:0 (16.3%), C_14:0 2OH (15.9%) and summed feature 3 (comprising C_16:1 ω7c and/or C_15:0 iso 2OH, 11.7%). The polar lipids were sphingoglycolipid, phosphatidyletha-nolamine, phosphatidylglycerol, diphosphatidylglycerol and unidentified glycolipid. Based on the evidence from the polyphasic taxonomic study, the strain should be classified as a new species of the genus Sphingomonas. As a result, the name Sphingomonas jejuensis sp. nov. (type strain MS-31^T =KCTC 23321^T =NBRC 107775^T) is proposed.     

<Emphasis Type="Italic">Kazachstania intestinalis</Emphasis> sp. nov., an ascosporogenous yeast from the gut of passalid beetle <Emphasis Type="Italic">Odontotaenius disjunctus</Emphasis>

Three ascosporogenous yeast strains were isolated from the gut of the passalid beetle, Odontotaenius disjunctus, inhabiting on rotten oak trees. DNA sequence comparison and other taxonomic characteristics identified the strains as a novel species in the genus Kazachstania. The name Kazachstania intestinalis sp. nov. (type strain EH085^T = ATCC MYA-4658^T = CBS 11839^T) is proposed for the strains. The yeast is homothallic, producing persistent asci with 1–4 spheroidal ascospores. Molecular phylogeny from ribosomal RNA gene sequences placed this novel species on the basal lineage of a clade including Kazachstania lodderae, Kazachstania exigua, Kazachstania martiniae, and other related Kazachstania spp., but none of those species was a close sister to K. intestinalis.     

<Emphasis Type="Italic">Singulispaera mucilagenosa</Emphasis> sp. nov., a novel acid-tolerant representative of the order <Emphasis Type="Italic">Planctomycetales</Emphasis>

Two novel strains of budding bacteria, Z-0071^T and Z-0072, were isolated from dystrophic humified waters formed by xylotrophic fungi in the course of spruce wood degradation. The cells of both strains are coccoid (0.95–1.80 μm), nonmotile, single or arranged in pairs. The cells have a complex system of intracellular membranes and are covered with fimbriae and surrounded by a mucous capsule up to 0.3 μm thick. Both strains are aerobic organoheterotrophic, mesophilic, and acid-tolerant microorganisms that are able to grow under microaerobic conditions. They utilize N-acetyl-glucosamine, carbohydrates, and lactate as growth substrates. The strains grow in a pH range of 4.0–7.5 with an optimum at 6.0–6.5. The temperature range for growth is 4–30°C, with an optimum at 25–28°C. Strains Z-0071^T and Z-0072, inhabitants of dystrophic low-mineral waters, are NaCl-sensitive: the NaCl content in the media above 0.5 g/l inhibited growth. The main fatty acids of strains Z-0071^T and Z-0072 are C_16:0, C_18:1ω9c, and C_{18:2ω9c, 12c}. The DNA G + C base content is 51.2–51.7 mol %. The sequences of the 16S rRNA gene fragments (1310 bp) of strains Z-0071^T and Z-0072 were found to be identical. The obtained sequences showed a 94.3% similarity with the sequences of the type strain of the most closely related species Singulisphaera acidiphila MOB10≅T. The phenotypic and phylogenetic properties of strains Z-0071^T and Z-0072 support classification of these strains within the genus Singulisphaera as a new species Singulisphaera mucilagenosa sp. nov., with the type strain Z-0071^T (VKM B-2626).     

<Emphasis Type="Italic">Streptomyces urticae</Emphasis> sp. nov., isolated from rhizosphere soil of <Emphasis Type="Italic">Urtica urens</Emphasis> L.

Two novel Gram-stain positive, spore-forming, aerobic actinomycetes, designated NEAU-PCY-1^T and NEAU-PCY-2, were isolated from rhizosphere soil of Urtica urens L. collected from Anshan, Liaoning Province, northeast China. The 16S rRNA gene sequence analysis showed that strains NEAU-PCY-1^T and NEAU-PCY-2 exhibited 99.8% similarity with each other and are closely related to Streptomyces abietis DSM 42080^T (98.2, 98.3%) and Streptomyces fildesensis DSM 41987^T (98.0, 98.1%). Phylogenetic analysis based on the 16S rRNA gene sequences indicated that the two strains formed a cluster with these two closely related species. Moreover, DNA–DNA hybridization results and some phenotypic, physiological and biochemical properties differentiated the two strains from their close relatives in the genus Streptomyces. Based on a polyphasic taxonomy study, strains NEAU-PCY-1^T and NEAU-PCY-2 are considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces urticae sp. nov. is proposed, with NEAU-PCY-1^T (=?DSM 105115^T?=?CCTCC AA 2017015^T) as the type strain.     

<Emphasis Type="Italic">Saturnispora serradocipensis</Emphasis> sp. nov. and <Emphasis Type="Italic">Saturnispora gosingensis</Emphasis> sp. nov., two ascomycetous yeasts from ephemeral habitats

Two novel ascomycetous yeast species, Saturnispora serradocipensis and Saturnispora gosingensis, were isolated from leaf detritus in a tropical stream of Southeastern Brazil and a mushroom collected in Taiwan, respectively. Analysis of the D1/D2 domains of the large-subunit of the rRNA gene of these strains showed that these species are related to Saturnispora hagleri, their closest relative. Saturnispora serradocipensis and S. gosingensis differed from S. hagleri, respectively, by seven nucleotide substitutions and two indels and three nucleotide substitutions and three indels in D1/D2 rRNA sequences. The two new species differ from each another by four nucleotide substitutions and one indel in D1/D2 rRNA sequences. However, the ITS sequences of S. serradocipensis, S. gosingensis and S. hagleri were quite divergent, showing that they are genetically separate species. The type strain of S. serradocipensis is UFMG-DC-198^T (=CBS 11756^T = NRRL Y-48717^T), and of S. gosingensis GA4M05^T is (CBS 11755^T = NRRL Y-48718^T).     

<Emphasis Type="Italic">Kribbella podocarpi</Emphasis> sp. nov., isolated from the leaves of a yellowwood tree (<Emphasis Type="Italic">Podocarpus latifolius</Emphasis>)

An endophytic actinobacterial strain was isolated from a yellowwood tree growing on the slope of Devil’s Peak, Cape Town, South Africa. Analysis of the 16S rRNA gene showed that the strain belongs to the genus Kribbella. Phylogenetic analyses using the 16S rRNA gene and multilocus sequence analysis using the concatenated gene sequences of the gyrB, rpoB, relA, recA and atpD genes showed that strain YPL1^T is closely related to the type strains of Kribbella karoonensis and Kribbella shirazensis. DDH experiments showed that strain YPL1^T is a distinct genomic species from its close phylogenetic relative, K. karoonensis Q41^T. Physiological comparisons further showed that strain YPL1^T is phenotypically distinct from the type strains of Kribbella jejuensis, Kribbella aluminosa, K. karoonensis, K. shirazensis and Kribbella swartbergensis. Strain YPL1^T is thus presented as the type strain of a novel species, for which the name Kribbella podocarpi sp. nov. (= DSM 29424^T = NRRL B-65063^T), is proposed.     

<Emphasis Type="Italic">Bacillus berkeleyi</Emphasis> sp. nov., isolated from the sea urchin <Emphasis Type="Italic">Strongylocentrotus intermedius</Emphasis>

A bacterial strain, designated KMM 6244^T, was isolated from the sea urchin Strongylocentrotus intermedius and subjected to a polyphasic taxonomic investigation. The bacterium was found to be heterotrophic, aerobic, non-motile and spore-forming. Comparative phylogenetic analysis based on 16S rRNA gene sequencing placed the marine isolate in the genus Bacillus. The nearest neighbor of strain KMM 6244^T was Bacillus decolorationis LMG 19507^T with a 16S rRNA gene sequence similarity of 98.0%. Sequence similarities with the other recognized Bacillus species were less than 96.0%. The results of the DNA–DNA hybridization experiments revealed a low relatedness (37%) of the novel isolate with the type strain of B. decolorationis LMG 19507^T. Strain KMM 6244^T grew at 4–45°C and with 0–12% NaCl. It produced catalase and oxidase and hydrolyzed aesculin, casein, gelatin and DNA. The predominant fatty acids were anteiso-C_15:0, iso-C_15:0, anteiso-C_17:0, C_15:0, iso-C_16:0 and iso-C_14:0. The DNA G + C content was 39.4 mol%. A combination of phylogenetic, genotypic and phenotypic data clearly indicated that strain KMM 6244^T represents a novel species in the genus Bacillus, for which the name Bacillus berkeleyi sp. nov. is proposed. The type strain is KMM 6244^T (KCTC 12718^T = LMG 26357^T).     

<Emphasis Type="Italic">Cohnella ferri</Emphasis> sp. nov. A Novel Member of the Genus <Emphasis Type="Italic">Cohnella</Emphasis> Isolated from Haematite Ore

The taxonomic position of a Gram-positive, endo-spore forming bacterium isolated from a haematite ore sample was analyzed by a polyphasic approach. The strain designated as HIO-4^T matched most of the phenotypic and chemical characteristics of the genus Cohnella and represents a novel species. The sequence of the almost complete 16S rRNA (1489 bases) was compared with those of previously studied Cohnella type strains and confirmed that the strain belongs to the genus Cohnella. Strain HIO-4^T differs from all other species of Cohnella by at least 3.9% at the 16S rRNA level and the moderately related species are Cohnella phaseoli (96.1%) and Cohnella yongneupensis (96.1%), respectively. Predominant polar lipids are diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylethanolamine (PE); few unknown phospholipids, mannose containing lipid, aminophospholipid and aminophosphoglycolipids. The results of physiological and biochemical tests allowed the genotypic and phenotypic distinctiveness of strain HIO-4^T with its phylogenetic relatives and suggest that the strain HIO-4^T should be recognized as a novel species, for which the name Cohnella ferri sp. nov. is proposed. The type strain is HIO-4^T (=MTCC 8365^T = JCM 16139^T)     

<Emphasis Type="Italic">Flavobacterium koreense</Emphasis> sp. nov., <Emphasis Type="Italic">Flavobacterium chungnamense</Emphasis> sp. nov., and <Emphasis Type="Italic">Flavobacterium cheonanense</Emphasis> sp. nov., isolated from a freshwater reservoir

Taxonomic studies were performed on three strains isolated from Cheonho reservoir in Cheonan, Korea. The isolates were Gram-negative, aerobic, rod-shaped, non-motile, catalase-positive, and oxidase-positive. Colonies on solid media were cream-yellow, smooth, shiny, and circular. Phylogenetic analysis of the 16S rRNA gene sequences revealed that these strains belong to the genus Flavobacterium. The strains shared 98.6–99.4% sequence similarity with each other and showed less than 97% similarity with members of the genus Flavobacterium with validly published names. The DNA-DNA hybridization results confirmed the separate genomic status of strains ARSA-42^T, ARSA-103^T, and ARSA-108^T. The isolates contained menaqui-none-6 as the predominant menaquinone and iso-C_15:0, iso-C_15:0 3-OH, iso-Ci_15:1 G, and iso-C_16:0 3-OH as the major fatty acids. The genomic DNA G+C content of the isolates were 31.4–33.2 mol%. According to the phenotypic and genotypic data, these organisms are classified as representative of three novel species in the genus Flavobacterium, and the name Flavobacterium koreense sp. nov. (strain ARSA-42^T =KCTC 23182^T =JCM 17066^T =KACC 14969^T), Flavobacterium chungnamense sp. nov. (strain ARSA-103^T =KCTC 23183^T =JCM 17068^T =KACC 14971^T), and Flavobacterium cheonanense sp. nov. (strain ARSA-108^T =KCTC 23184^T =JCM 17069^T =KACC 14972) are proposed.     

<Emphasis Type="Italic">Ogataea saltuana</Emphasis> sp. nov., a novel methanol-assimilating yeast species

Four ascosporulating strains of an undescribed methanol-assimilating yeast species were isolated from forest habitats in Hungary. Three were recovered from rotten wood and one from leaves of a sessile oak (Quercus petraea). An additional isolate of the undescribed species sharing similar phenotypic characters with the above-noted strains was recovered from the gut of an unidentified beetle collected from under the bark of a coniferous tree in Bulgaria. A closely related, but somewhat divergent strain was recovered from insect frass in a Ponderosa pine (Pinus ponderosa) collected in New Mexico, USA. Analysis of the D1/D2 sequences of the LSU rRNA gene placed the new species in the Ogataea clade. The ITS and the D1/D2 LSU sequences of the rRNA gene repeats were compared for the above-noted strains and that of the type strain of Ogataea zsoltii, the closest neighbour among currently recognized Ogataea species. Their relatedness was investigated by parsimony network analysis as well. As a result of the sequence analysis, it was concluded that the six strains isolated from tree associated habitats represent a single new yeast species. Ogataea saltuana sp. nov. is proposed to accommodate these strains. The type strain NCAIM Y.01833^T (CBS 10795^T, NRRL Y-48448^T) was recovered from rotten wood of Scotch pine (Pinus silvestris) in Hungary. The GenBank accession number for the D1/D2 domain nuclear large subunit rRNA gene sequence of strain NCAIM Y.01833^T (CBS 10795^T, NRRL Y-48448^T) is EU327033. The MycoBank number of the new species is MB 519966.     

<Emphasis Type="Italic">Streptomyces sudanensis</Emphasis> sp. nov., a new pathogen isolated from patients with actinomycetoma

Nine strains isolated from mycetoma patients and received as Streptomyces somaliensis were the subject of a polyphasic taxonomic study. The organisms shared chemical markers consistent with their classification in the genus Streptomyces and formed two distinct monophyletic subclades in the Streptomyces 16S rRNA gene tree. The first subclade contained four organisms, including the type strain of S. somaliensis, and the second clade the remaining five strains which had almost identical 16S rRNA sequences. Members of the two subclades were sharply separated using DNA:DNA relatedness and phenotypic data which also showed that the subclade 1 strains formed an heterogeneous group. In contrast, the subclade 2 strains were assigned to a single genomic species and had identical phenotypic profiles. It is evident from these data that the subclade 2 strains should be recognised as a new species of Streptomyces. The name proposed for this new species is Streptomyces sudanensis sp. nov. The type strain is SD 504^T (DSM = 41923^T = NRRL B-24575^T). Erika T. Quintana and Katarzyna Wierzbicka contributed equally to this work. The GenBank accession numbers for the 16S rRNA gene sequences of Streptomyces somaliensis DSM 40738^T and Streptomyces sudanensis DSM 41607, DSM 41608, DSM 41609, SD 504^T and SD 509 are EF540897, EF540898, EF540999, EF515876 and EF540900.     

The diversity of rhizobia nodulating the <Emphasis Type="Italic">Medicago</Emphasis>, <Emphasis Type="Italic">Melilotus</Emphasis> and <Emphasis Type="Italic">Trigonella</Emphasis> inoculation group in Egypt is marked by the dominance of two genetic types

Twenty four rhizobial strains were isolated from root nodules of Melilotus, Medicago and Trigonella plants growing wild in soils throughout Egypt. The nearly complete 16S rRNA gene sequence from each strain showed that 12 strains (50 %) were closely related to the Ensifer meliloti LMG6133^T type strain with identity values higher than 99.0 %, that 9 (37.5 %) strains were more than 99 % identical to the E. medicae WSM419^T type strain, and that 3 (12.5 %) strains showed 100 % identity with the type strain of N. huautlense S02^T. Accordingly, the diversity of rhizobial strains nodulating wild Melilotus, Medicago and Trigonella species in Egypt is marked by predominance of two genetic types, E. meliloti and E. medicae, although the frequency of isolation was slightly higher in E. meliloti. Sequencing of the symbiotic nodC gene from selected Medicago and Melilotus strains revealed that they were all similar to those of the E. meliloti LMG6133^T and E. medicae WSM419^T type strains, respectively. Similarly, nodC sequences of strains identified as members of the genus Neorhizobium were more than 99 % identical to that of N. galegae symbiovar officinalis HAMBI 114.     

Role of trehalose synthesis pathways in salt tolerance mechanism of <Emphasis Type="Italic">Rhodobacter sphaeroides</Emphasis> f. sp. <Emphasis Type="Italic">denitrificans</Emphasis> IL106

Two strains of trichloroethylene (TCE)-degrading bacteria were isolated from soils at polluted and unpolluted sites. The isolates, strains TE26^T and K6, showed co-substrate-independent TCE-degrading activity. TCE degradation was accelerated by preincubation with tetrachloroethylene, cis-dichloroethylene (DCE) and 1,1-DCE. TCE-degrading activities of strains TE26^T and K6 were 0.23, 0.24 mol min^–1 g^–1 dry cells, respectively. 16S rDNA sequences of strains TE26^T and K6 were almost identical (99.7% similarity), and most closely related to Ralstonia basilensis (ATCC17697^T) (98.5% similarity). From the results of DNA–DNA hybridizations, strain TE26^T was genetically coherent to strain K6 (94 and 88% hybridization), and exhibited lower relatedness to R. basilensis (DSM11853^T) (44% and 15%). In addition, because of the differences in chemotaxonomic properties, strain TE26^T and strain K6 appear to be distinct from all established species of the Ralstonia group. Based on these results and the proposal of transferring R. basilensis and related species to Wautersia gen. nov., we propose that these strains should be assigned to the genus Wautersia as Wautersia numadzuensis sp. nov.     

<Emphasis Type="Italic">Pseudonocardia bannaensis</Emphasis> sp. nov., a novel actinomycete isolated from the surface-sterilized roots of <Emphasis Type="Italic">Artemisia annua</Emphasis> L.

During the course of our research on new actinobacterial sources, a novel actinomycete strain YIM 63101^T was isolated from the surface-sterilized roots of Artemisia annua L. collected from Xishuangbanna, Yunnan province, south-west China and characterized by using a polyphasic approach. The strain formed well-differentiated aerial and substrate mycelia. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM 63101^T belongs to the genus Pseudonocardia, with highest similarity to “Pseudonocardia artemisiae YIM 63587^T” (99.4%). Sequence similarities between strain YIM 63101^T and the other Pseudonocardia species ranged from 97.0 (Pseudonocardia saturnea IMSNU 20052^T) to 94.0% (Pseudonocardia compacta IMSNU 20111^T). The chemotaxonomic characteristics, such as cell wall diaminopimelic acid, whole-cell sugars, fatty acid components and the major menaquinones suggested that the organism belonged to the genus Pseudonocardia. The G + C content of the genomic DNA was 69.4 mol%. Based on comparative analysis of physiological, biochemical and chemotaxonomic data, including low DNA–DNA hybridization results, it is proposed that strain YIM 63101^T represents a novel species of the genus Pseudonocardia, named Pseudonocardia bannaensis sp. nov. The type strain is YIM 63101^T (= CCTCC AA 208077 ^T = DSM 45300^T).     

<Emphasis Type="Italic">Salinarchaeum laminariae</Emphasis> gen. nov., sp. nov.: a new member of the family <Emphasis Type="Italic">Halobacteriaceae</Emphasis> isolated from salted brown alga <Emphasis Type="Italic">Laminaria</Emphasis>

Halophilic archaeal strains R26^T and R22 were isolated from the brown alga Laminaria produced at Dalian, Liaoning Province, China. Cells from the two strains were pleomorphic rods and Gram negative, and colonies were red pigmented. Strains R26^T and R22 were able to grow at 20–50°C (optimum 37°C) in 1.4–5.1 M NaCl (optimum 3.1–4.3 M) at pH 5.5–9.5 (optimum pH 8.0–8.5) and neither strain required Mg²⁺ for growth. Cells lyse in distilled water and the minimum NaCl concentration required to prevent cell lysis was 8% (w/v) for strain R26^T and 12% (w/v) for strain R22. The major polar lipids of the two strains were phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and minor phosphatidylglycerol sulfate; glycolipids were not detected. Phylogenetic analyses based on 16S rRNA genes and rpoB′ genes revealed that strains R26^T and R22 formed a distinct clade with the closest relative, Natronoarchaeum mannanilyticum. The DNA G+C content of strains R26^T and R22 was 65.8 and 66.4 mol%, respectively. The DNA–DNA hybridization value between strains R26^T and R22 was 89%. The phenotypic, chemotaxonomic and phylogenetic properties suggest that the strains R26^T and R22 represent a novel species in a new genus within the family Halobacteriaceae, for which the name Salinarchaeum laminariae gen. nov., sp. nov. is proposed. The type strain is R26^T (type strain R26^T = CGMCC 1.10590^T = JCM 17267^T, reference strain R22 = CGMCC 1.10589).     

<Emphasis Type="Italic">Paenibacillus camelliae</Emphasis> sp. nov., isolated from fermented leaves of <Emphasis Type="Italic">Camellia sinensis</Emphasis>

A novel bacterium, strain blls-2^T was isolated from Pu’er tea. The isolate was Gram-positive, endospore-forming motile rod that grew at 15∼42°C and pH 6.0∼10.2. The DNA G+C content was 48.3 mol%, the predominant isoprenoid quinone was MK-7, and the predominant cellular fatty acid was anteiso-C15:0 (54.2%) followed by C16:0 (15.5%) and iso-C16:0 (8.2%). The polar lipid pattern of blls-2^T was characterized by the presence of diphosphatidylglycerol, phosphatidylethanolamine, and phosphatidylglycerol. Phy-logenetic analysis based on 16S rRNA gene sequence showed that the strain was affiliated within the Paenibacillaceae. The strain was most closely related to Paenibacillus granivorans A30^T, with a similarity of 97.1%. Based on the phylogenetic and phenotypic characteristics of strain blls-2^T, the isolate is thought to represent a novel taxon in the genus Paenibacillus. The name Paenibacillus camelliae sp. nov. is proposed for the fermented tea isolate; the type strain is blls-2^T (= KCTC 13220^T= CECT 7361^T).     

<Emphasis Type="Italic">Halorubrum cibi</Emphasis> sp. nov., an extremely halophilic archaeon from salt-fermented seafood

Strain B31^T is a Gram-staining-negative, motile, and extremely halophilic archaeon that was isolated from salt-fermented seafood. Its morphology, physiology, biochemical features, and 16S rRNA gene sequence were determined. Phylogenetic analysis of its 16S rRNA gene sequence and composition of its major polar lipids placed this archaeon in the genus Halorubrum of the family Halobacteriaceae. Strain B31^T showed 97.3, 97.2, and 96.9 % 16S rRNA similarity to the type strains of Halorubrum alkaliphilum, Hrr. tibetense, and Hrr. vacuolatum, respectively. Its major polar lipids were phosphatidylglycerol (PG), phosphatidylglycerol phosphate methyl ester (PGP-Me) and sulfated diglycosyl diether (S-DGD). Genomic DNA from strain B31^T has a 61.7 mol% G+C content. Analysis of 16S rRNA gene sequences, as well as physiological and biochemical tests, identified genotypic and phenotypic differences between strain B31^T and other Halorubrum species. The type strain of the novel species is B31^T (=JCM 15757^T =DSM 19504^T).
