Acidovorax soli sp. nov., isolated from landfill soil

Abstract

A Gram-negative, aerobic, rod-shaped, non-motile strain, BL21T, was isolated from landfill soil in Pohang, Korea. Strain BL21T grew optimally at pH 7.0, 30 °C and 0 % NaCl (w/v). Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain BL21T belonged to the class Betaproteobacteria and was related to the genus Acidovorax. The 16S rRNA gene sequence of strain BL21T was less than 98.30 % similar to those of other species in the genus Acidovorax. DNA–DNA hybridization values with phylogenetically related species of the genus Acidovorax were only 11.7–28.4 %. The major fatty acid components included summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c), C16 : 0, C18 : 1 ω7c and C10 : 0 3-OH. The DNA G+C content was 60.9 mol%. For these reasons, strain BL21T (=KCTC 22399T =JCM 15909T) is proposed as a novel species in the genus Acidovorax, with the name Acidovorax soli sp. nov.
