A non-motile, rod-shaped bacterium, designated strain A5T, was isolated from a dye wastewater treatment facility in the Republic of Korea. Cells were Gram-reaction-negative, aerobic, catalase-positive and oxidase-negative. The major fatty acids were C16 : 0, C18 : 0, iso-C15 : 0 and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) and the major polar lipid was phosphatidylethanolamine. The strain contained MK-7 as the only isoprenoid quinone and the DNA G+C content was 41.2 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain A5T forms an evolutionary lineage within the radiation encompassing the members of genus Mucilaginibacter , with Mucilaginibacter lutimaris BR-3T as its nearest neighbour (96.6 % sequence similarity). A number of phenotypic characteristics distinguished strain A5T from the members of the genus Mucilaginibacter . On the basis of the evidence presented in this study, strain A5T represents a novel species, for which the name Mucilaginibacter defluvii sp. nov. is proposed. The type strain is A5T ( = KCTC 23922T = JCM 18283T).

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).

The strain grew well on R2A agar, tryptone soya agar, Mueller-Hinton agar and nutrient agar. The major polar lipid profile comprised phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, aminophospholipid and glycolipid. The major respiratory quinone was ubiquinone 8 (Q-8). The main fatty acids were C17 : 0 cyclo, C16 : 0, C16 : 0 3-OH, C19 : 0 cyclo ω8c and C12 : 0. The DNA G+C content of the isolated strain based on the whole genome sequence was 63.4 mol%. The average nucleotide identity and digital DNA–DNA hybridization values between strain LD6T and its reference type strains ranged from 80.3 to 82.4%, and from 23.7 to 33.7%, respectively. Based on phenotypic, chemotypic and genotypic evidence, strain LD6T could be differentiated phylogenetically and phenotypically from the recognized species of the genus Paraburkholderia . Therefore, strain LD6T is considered to represent a novel species, for which the name Paraburkholderia flava sp. nov. is proposed. The type strain is LD6T (=KACC 21387T=JCM 33640T).
