A novel bacterial strain, designated DCY54T, was isolated from a field cultivated with ginseng in Yongin, Republic of Korea. Cells were Gram-reaction-negative, yellow-pigmented, rod-shaped, non-spore-forming, and strictly aerobic. They were motile by gliding and produced flexirubin-type pigments. Growth occurred optimally at 25–30 °C, at pH 5.0–7.0 and in the presence of 0–1 % NaCl. The 16S rRNA sequence analysis demonstrated that strain DCY54T was most closely related to Flavobacterium defluvii EMB117T (96.9 %). The only isoprenoid quinone of strain DCY 54T was menaquinone-6 (MK-6) and the major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid. The major cellular fatty acids (>15 %) were iso-C15 : 0, summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH) and C16 : 0. The DNA G+C content was 33.3 mol%. Phylogenetic inference and phenotypic data supported affiliation of strain DCY54T to the genus Flavobacterium . Several physiological and biochemical tests differentiated strain DCY54T from the species of the genus Flavobacterium with validly published names. On the basis of data from a polyphasic study, strain DCY54T represents a novel species of the genus Flavobacterium for which the name Flavobacterium ginsengisoli sp. nov. is proposed. The type strain is DCY54T ( = KCTC 23318T = JCM 17336T).

A Gram-reaction-negative, strictly aerobic, non-motile, non-spore-forming and rod-shaped bacterial strain, designated THG-45T, was isolated from soil of a ginseng field of Pocheon province in the Republic of Korea and its taxonomic position was investigated by a polyphasic approach. Growth occurred at 4–30 °C, at pH 5.5–9.0 and with 0–2 % (w/v) NaCl on nutrient agar. On the basis of 16S rRNA gene sequence similarity, strain THG-45T was shown to belong to the genus Pedobacter and was related to Pedobacter borealis G-1T (98.8 %), P. alluvionis NWER-II11T (97.9 %), P. agri PB92T (97.9 %), P. terrae DS-57T (97.5 %), P. suwonensis 15-52T (97.4 %), P. sandarakinus DS-27T (97.0 %) and P. soli 15-51T (97.0 %), but DNA relatedness between strain THG-45T and these strains was below 36 %. The G+C content of the genomic DNA was 39 mol%. The only isoprenoid quinone detected in strain THG-45T was menaquinone-7 (MK-7). The predominant fatty acids were iso-C15 : 0, summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c) and iso-C17 : 0 3-OH, and the major polar lipids were phosphatidylethanolamine and an unidentified aminophosphoglycolipid. Phenotypic data and phylogenetic inference supported the affiliation of strain THG-45T to the genus Pedobacter , and a number of biochemical tests differentiated strain THG-45T from the recognized species of the genus Pedobacter . Therefore, the novel isolate represents a novel species, for which the name Pedobacter ginsenosidimutans sp. nov. is proposed, with THG-45T as the type strain ( = KACC 14530T = JCM 16721T).

AbstractPseudomonas are ubiquitously occurring microorganisms and are known for their ability to produce antimicrobials. An endophytic bacterial strain NP-1 T, isolated from Eucalyptus dunnii leaves, exhibits antifungal properties against five tested phytopathogenic fungi. The strain is a Gram-negative rod-shaped bacterium containing a single polar flagellum. It is strictly aerobic, grows at 4–37 °C, 2–5% NaCl, and pH 3–7. The 16S rRNA sequence analysis showed that NP-1 T belongs to the Pseudomonas genus. Phylogenetic analysis based on four concatenated partial genes (16S rDNA, gyrB, rpoB and rpoD) and the phylogenomic tree indicated that NP-1 T belongs to Pseudomonas fluorescens lineage but is distinct from any known Pseudomonas species. The G + C mol % of NP-1 T genome is 63.96, and the differences between NP-1 T and related species are larger than 1. The digital DNA-DNA hybridization and tetranucleotide signatures are 23.8 and 0.97, which clearly separates strain NP-1 T from its closest neighbours, Pseudomonas coleopterorum and Pseudomonas rhizosphaerae. Its phenotypic and chemotaxonomic features confirmed its differentiation from related taxa. The results from this polyphasic approach support the classification of NP-1 T as a novel species of Pseudomonas, and the name of Pseudomonas eucalypticola is thus proposed for this strain, whose type is NP-1 T (= CCTCC M2018494T = JCM 33572 T).

A Gram-stain-negative bacterium, designated strain PF-30T, was isolated from floodwater of a paddy field in South Korea. Strain PF-30T was found to be a strictly aerobic, motile and pink-pigmented rods which can grow at 25–40 °C (optimum, 28 °C), at pH 5.0–9.0 (optimum pH 7.0) and at salinities of 0.5–3.0 % NaCl (optimum 0.5 % NaCl). Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain PF-30T belongs to the genus Elioraea , showing highest sequence similarity to Elioraea tepidiphila TU-7T (97.1%) and less than 91.3 % similarity with other members of the family Acetobacteraceae . The average nucleotide identity (ANI) and DNA–DNA relatedness between the strain PF-30T and E. tepidiphila TU-7T yielded an ANI value of 75.1 % and DNA–DNA relatedness of 11.7±0.7 %, respectively. The major fatty acids were identified as C18 : 0 and C18 : 1 ω7c. The predominant respiratory quinone was identified as Q-10. The DNA G+C content was determined to be 69.9 mol%. The strain PF-30T was observed to produce plant-growth-promoting materials such as indole-3-acetic acid (IAA), siderophore and phytase. On the basis of the results from phylogenetic, chemotaxonomic and phenotypic data, we concluded that strain PF-30T represents a novel species of the genus Elioraea , for which the name Elioraea rosea sp. nov. is proposed. The type strain is PF-30T (=KACC 19985T=NBRC 113984T).
