A bacterial strain (DB5T), with polysaccharide-degrading activities, was isolated from garden soil in Daejeon, Republic of Korea. The cells were Gram-positive, aerobic or facultatively anaerobic, non-motile straight rods. Phylogenetic analysis based on 16S rRNA gene sequences showed that this strain belongs to the genus Cellulomonas and that it is most closely related to Cellulomonas xylanilytica LMG 21723T and Cellulomonas humilata ATCC 25174T (98·0 and 97·9 % similarity, respectively). Chemotaxonomic data also supported the classification of strain DB5T in the genus Cellulomonas, i.e. l-ornithine as the cell-wall diamino acid, anteiso-C15 : 0 and iso-C15 : 0 as the major fatty acids, MK-9(H4) as the predominant menaquinone and the presence of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylinositol mannosides in the polar lipid profile. The results of DNA–DNA hybridization in combination with chemotaxonomic and physiological data demonstrated that strain DB5T (=KCTC 19081T=NBRC 100819T) should be classified as the type strain of a novel species within the genus Cellulomonas, for which the name Cellulomonas terrae sp. nov. is proposed.

Diamino Acid

A Gram-stain-positive, aerobic, non-motile and coccoid-shaped bacterium, designated XNB-1T, was isolated from farmland soil in Taian, Shandong province, China. Strain XNB-1T contained iso-C15 : 0 and iso-C16 : 0 as the predominant fatty acids. The diagnostic diamino acid of the peptidoglycan was ornithine, and the interpeptide bridge was l-Orn←Gly(1, 2)←d-Glu. The polar lipid profile of strain XNB-1T consisted of diphosphatidylglycerol, phosphatidylglycerol, an unidentified phosphoglycolipid and three unidentified phospholipids. The predominant menaquinone of strain XNB-1T was MK-8(H4) and the DNA G+C content was 70.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain XNB-1T belonged to the genus Ornithinicoccus , and shared the highest similarity with Ornithinicoccus hortensis HKI 0125T (96.0 %), followed by Ornithinicoccus halotolerans EGI 80423T (95.5 %). Genome-based analysis of average nucleotide identity of strain XNB-1T with O. hortensis HKI 0125T and O. halotolerans EGI 80423T yielded values of 73.1 and 73.3 %, respectively, while the digital DNA–DNA hybridization values were 19.5 and 19.9 %, respectively. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain XNB-1T is considered to represent a novel species of the genus Ornithinicoccus , for which the name Ornithinicoccus soli sp. nov. is proposed. The type strain is XNB-1T (=CCTCC AB 2019099T=KCTC 49259T).

An alkalitolerant and moderately halophilic strain, designated KB23T, characterized by optimal growth at pH 8.0–9.0 and in the presence of 5–7 % (w/v) NaCl, was isolated from a reed (Phragmites australis) periphyton sample originating from an extremely shallow, alkaline soda pond located in Hungary. Cells of strain KB23T were Gram-stain-positive, motile straight rods. Strain KB23T was facultatively anaerobic, catalase-positive, oxidase-negative and contained peptidoglycan type A4β (l-Orn–d-Asp). MK-9(H4) was the predominant isoprenoid quinone and anteiso-C15 : 0, C16 : 0 and anteiso-C15 : 1 were the major cellular fatty acids. The DNA G+C content of strain KB23T was 74.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that this strain belongs to the genus Cellulomonas and that it is related most closely to Cellulomonas flavigena DSM 20109T (97.35 % similarity), Cellulomonas terrae DB5T (96.81 %), Cellulomonas iranensis OT (96.75), Cellulomonas chitinilytica X.bu-bT (96.60 %), Cellulomonas persica IT (96.53 %), Cellulomonas composti TR7-06T (96.45 %), Cellulomonas biazotea DSM 20112T (96.34 %) and Cellulomonas fimi DSM 20113T (96.20 %). According to these results, together with DNA–DNA hybridization and physiological data, strain KB23T is considered to represent a novel species of the genus Cellulomonas, for which the name Cellulomonas phragmiteti sp. nov. is proposed. The type strain is KB23T ( = DSM 22512T  = NCAIM B002303T).

Two endophytic strains, coded MOVP5T and MOPV6, were isolated from nodules of Phaseolus vulgaris plants grown on agricultural soil in Southeastern Spain, and were characterized through a polyphasic taxonomy approach. Their 16S rRNA gene sequences showed 99.3 and 99.4 %, 98.9 and 99.6 %, and 99.0 and 98.7% similarity to ‘ A. deltaense ’ YIC 4121T, A. radiobacter LGM 140T, and A. pusense NRCPB10T, respectively. Multilocus sequence analysis based on sequences of recA and atpD genes suggested that these two strains could represent a new Agrobacterium species with less than 96.5 % similarity to their closest relatives. PCR amplification of the telA gene, involved in synthesis of protelomerase, confirmed the affiliation of strains MOPV5T and MOPV6 to the genus Agrobacterium . Whole genome average nucleotide identity and digital DNA–DNA hybridization average values were less than 95.1 and 66.7 %, respectively, with respect to its closest related species. Major fatty acids in strain MOPV5T were C18 : 1 ω7c/C18 : 1 ω6c in summed feature 8, C19 : 0 cyclo ω8c, C16 : 0 and C16 : 0 3-OH. Colonies were small to medium, pearl-white coloured on YMA at 28 °C and growth was observed at 10–42 °C, pH 5.0–10.0 and with 0.0–0.5 % (w/v) NaCl. The DNA G+C content was 59.9 mol%. These two strains differ from all other genomovars of Agrobacterium found so far, including those that have not yet given a Latin name. The combined genotypic, phenotypic and chemotaxonomic data support the classification of strain MOPV5T as representing a novel species of Agrobacterium , for which the name Agrobacterium leguminum sp. nov. is proposed. The type strain is MOPV5T (=CECT 30096T=LMG 31779T).

Phenotypic Characteristics

Phylogenetic analysis of ‘Sarraceniospora aurea’ NBRC 14752 and strain NBRC 15120, based on 16S rRNA gene sequences, revealed that these organisms are related to members of the genus Actinocorallia. These organisms contained glutamic acid, alanine and meso-diaminopimelic acid as cell-wall amino acids and the menaquinones MK-9(H4), MK-9(H6) and MK-9(H8). The chemotaxonomic characteristics of the strains were consistent with those of the genus Actinocorallia. However, DNA–DNA hybridization and phenotypic characteristics revealed that the strains differed from the recognized species of the genus Actinocorallia. Therefore, we propose that ‘Sarraceniospora aurea’ NBRC 14752 and strain NBRC 15120 be reclassified in the genus Actinocorallia as a novel species, Actinocorallia aurea sp. nov. (type strain NBRC 14752T=DSM 44434T).

Optimum Ph

A bacterial strain, designated FSY-8T, was isolated from a freshwater mesocosm in Taiwan and characterized using the polyphasic taxonomy approach. Cells of strain FSY-8T were aerobic, Gram-stain-negative, rod-shaped, non-motile and formed yellow coloured colonies on Reasoner's 2A agar. Growth occurred at 20–40 °C (optimum, 30–37 °C) and pH 5–7 (optimum, pH 6) and in the presence of 0–0.5 % NaCl (optimum, 0 %, w/v). The major fatty acids (>10 %) of strain FSY-8T were summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c) and summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c). The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, phosphatidylmonomethylethanolamine, phosphatidyldimethylethanolamine, sphingoglycolipid, diphosphatidylglycerol, an uncharacterized aminophospholipid, an uncharacterized glycolipid and an uncharacterized lipid. The major polyamine was spermidine. The major isoprenoid quinone was Q-10. The DNA G+C content was 64.8 mol %. Phylogenetic analyses based on 16S rRNA gene sequences and coding sequences of 92 protein clusters indicated that strain FSY-8T formed a phylogenetic lineage in the genus Novosphingobium . Strain FSY-8T showed 71.6–77.2 % average nucleotide identity and 19.9–22.8 % digital DNA–DNA hybridization identity with the strains of other Novosphingobium species. On the basis of phenotypic and genotypic properties and phylogenetic inference, strain FSY-8T should be classified in a novel species of the genus Novosphingobium , for which the name Novosphingobium ovatum sp. nov. is proposed. The type strain is FSY-8T (=BCRC 81051T=LMG 30053T=KCTC 52812T).

Abstract Strain WGZ8T was isolated from a soil sample of Puerh tea garden in Puer city, Southwest China. The isolate was rod-shaped, Gram-stain negative, aerobic, non-motile. Growth occurred within 0-3.0% (w/v) NaCl (optimal concentration, 0-1.0%), pH 5.0-11.0 (optimal pH, 7.0) and 10-40°C (optimal temperature, 28°C). 16S rRNA gene sequences based phylogenetic and phylogenomic analysis revealed that WGZ8T belonged to the genus Microvirga. Its major cellular fatty acids were C19:0 cyclo ω8c, C16:0, C18:1ω7c and/or C18:1ω6c. The profile of polar lipids included phosphatidyldimethylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, phosphatidylcholine, diphosphatidylglycerol and phosphatidyl-glycerol. The only respiratory quinone was detected as ubiquinone 10 (Q-10). The genome size of strain WGZ8T was 5.17MB, and the content of DNA G+C was 61%. Based on the results of digital DNA-DNA hybridization and phenotypic results, strain WGZ8T could be concluded as a novel species of the genus Microvirga, for which the name Microvirga puerhi sp. nov. is proposed. The type strain is WGZ8T (=CGMCC 1.19171T=JCM XXXXT).

A novel strain, C-138T, belonging to the genus Corynebacterium was isolated from a severe thigh liposarcoma infection and its differentiation from Corynebacterium xerosis and Corynebacterium freneyi is described. Analysis of 16S rRNA gene sequences, rpoB sequences and the PCR profile of the 16S–23S spacer regions was not conclusive enough to differentiate strain C-138T from C. xerosis and C. freneyi. However, according to DNA–DNA hybridization data, strain C-138T constitutes a member of a distinct novel species. It can be differentiated from strains of C. xerosis and C. freneyi by colony morphology, the absence of α-glucosidase and some biochemical characteristics such as glucose fermentation at 42 °C and carbon assimilation substrates. The name Corynebacterium hansenii sp. nov. is proposed for this novel species; the type strain is C-138T (=CIP 108444T=CCUG 53252T).
