Two Gram-staining-negative, rod-shaped, non-spore-forming bacterial strains, 1-2T and 1-4 were isolated from dry riverbed soil collected from the Xietongmen area of Tibet, China. On the basis of 16S rRNA gene sequence similarity, the novel strains were shown to belong to the genus Pedobacter, sharing <95 % sequence similarity with all recognized species of the genus Pedobacter. The major respiratory quinone was MK-7 and the predominant cellular fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (comprising iso-C16 : 1 ω7c and/or C16 : 1 ω6c). The DNA G+C contents were 37.2–37.6 mol%. Chemotaxonomic data supported the affiliation of the two new isolates to the genus Pedobacter and the results of physiological and biochemical tests confirmed that the new strains differed significantly from the recognized species of the genus Pedobacter. Therefore, the new isolates represent a novel species within the genus Pedobacter, for which the name Pedobacter glucosidilyticus sp. nov. is proposed. The type strain is 1-2T (=CCTCC AB 206110T=KCTC 22438T).

Major Respiratory Quinone

A novel bacterial strain, designated THG-PC7T, was isolated from fallow farmland soil in Yongin, South Korea. Cells of strain THG-PC7T were Gram-stain-negative, dark yellow, aerobic, rod-shaped and had gliding motility. Strain THG-PC7T grew optimally at 25–35 °C, at pH 7 and in the absence of NaCl. Comparative 16S rRNA gene sequence analysis identified strain THG-PC7T as belonging to the genus Lysobacter, exhibiting highest sequence similarity with Lysobacter ximonensis KCTC 22336T (98.7 %) followed by Lysobacter niastensis KACC 11588T (95.7 %). In DNA–DNA hybridization tests, DNA relatedness between strain THG-PC7T and its closest phylogenetic neighbour L. ximonensis was below 25 %. The DNA G+C content of the novel isolate was determined to be 62.5 mol%. Flexirubin-type pigments were found to be present. The major cellular fatty acids were determined to be iso-C15 : 0, iso-C16 : 0, anteiso-C15 : 0 and iso-C17 : 1ω9c. The major respiratory quinone was identified as ubiquonone-8 (Q8). The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and an unidentified aminophospolipid. On the basis of results from DNA–DNA hybridization and the polyphasic data, strain THG-PC7T represents a novel species of the genus Lysobacter, for which the name Lysobacter novalis sp. nov. is proposed. The type strain is THG-PC7T( = KACC 18276T = CCTCC AB 2014319T).

Taxonomic Approach

The taxonomic position of three bacterial strains, Asr22-19T, NBRC 101035 and NBRC 101041, isolated from shellfish in Japan, was determined by using a polyphasic taxonomic approach. The strains were facultatively anaerobic, motile by gliding and Gram-staining-negative slender rods. Their major respiratory quinone was menaquinone-7 and their predominant cellular fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 0 3-OH, C16 : 0 3-OH, and C16 : 0. The G+C content of the genomic DNA was 42.0–42.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strains clustered with the genus Persicobacter in the family ‘Flammeovirgaceae’. DNA–DNA relatedness values were higher than 68 % among strains Asr22-19T, NBRC 101035 and NBRC 101041, and were lower than 28 % between strain Asr22-19T and Persicobacter diffluens NBRC 15940T. The three novel strains could be differentiated from Persicobacter diffluens by several phenotypic characteristics. On the basis of these results, the novel species Persicobacter psychrovividus sp. nov. (type strain Asr22-19T=NBRC 101262T=CIP 109100T) is proposed and emended descriptions are given for the genus Persicobacter and for Persicobacter diffluens.

A bacterial strain (designated KMY03T) that possesses β-glucosidase activity was isolated from soil from a ginseng field in South Korea and was characterized in order to determine its taxonomic position. The bacterium was found to comprise Gram-negative, rod-shaped, motile cells with unipolar polytrichous flagella. On the basis of 16S rRNA gene sequence similarity, strain KMY03T was shown to belong to the family Burkholderiaceae of the Betaproteobacteria, being most closely related to Burkholderia caledonica LMG 19076T (97.8 %), Burkholderia terricola LMG 20594T (97.5 %), Burkholderia xenovorans LMG 21463T (97.4 %) and Burkholderia phytofirmans LMG 22146T (97.3 %). Chemotaxonomic data (major ubiquinone, Q-8; major fatty acids, C17 : 0 cyclo, C16 : 0, C19 : 0 cyclo ω8c and summed feature 2) supported the affiliation of the novel strain with the genus Burkholderia. The results of DNA–DNA hybridizations and physiological and biochemical tests allowed the strain to be differentiated genotypically and phenotypically from Burkholderia species with validly published names. On the basis of these data, strain KMY03T represents a novel species of the genus Burkholderia, for which the name Burkholderia ginsengisoli sp. nov. is proposed. The type strain is KMY03T (=KCTC 12389T=NBRC 100965T).
