sp. nov., a novel acetic acid bacterium isolated from blueberry fruit ( L.).

Strain C17-3 was isolated from blueberry fruits collected from a farmland located in Damyang-gun, Jeollanam-do, Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences allocated strain C17-3 to the genus , where it occupied a rather isolated line of descent with 430A and LMG 27439 as the nearest neighbours (98.9 % sequence similarity to both species). The highest average nucleotide identity and digital DNA-DNA hybridization values were 76.3 % and 21.7 % with TBRC 12339; both values were well below the cutoff values for species delineation. Cells are strictly aerobic, Gram-stain-negative rods, catalase-positive and oxidase-negative. The DNA G+C content calculated from the genome sequence was 59.2 %. Major fatty acids were summed feature 8 (Cω6 and/or Cω7) and Ccyclo ω8. The major isoprenoid quinone was ubiquinone 9. On the basis of the results of phylogenetic analyses, phenotypic features and genomic comparisons, it is proposed that strain C17-3 represents a novel species of the genus and the name sp. nov. is proposed. The type strain is C17-3 (= KACC 21233 = LMG 31758).
