Acidovorax soli sp. nov., isolated from landfill soil.

A Gram-negative, aerobic, rod-shaped, non-motile strain, BL21(T), was isolated from landfill soil in Pohang, Korea. Strain BL21(T) grew optimally at pH 7.0, 30 °C and 0 % NaCl (w/v). Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain BL21(T) belonged to the class Betaproteobacteria and was related to the genus Acidovorax. The 16S rRNA gene sequence of strain BL21(T) 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-C(15 : 0) 2-OH and/or C(16 : 1)ω7c), C(16 : 0), C(18 : 1)ω7c and C(10 : 0) 3-OH. The DNA G+C content was 60.9 mol%. For these reasons, strain BL21(T) (=KCTC 22399(T) =JCM 15909(T)) is proposed as a novel species in the genus Acidovorax, with the name Acidovorax soli sp. nov.
