Devosia Soli Sp Nov., Isolated From Greenhouse Soil In Korea

A Gram-negative, obligately aerobic, rod-shaped bacterium was isolated from greenhouse soil used to cultivate lettuce. The strain, GH2-10(T), was characterized on the basis of phenotypic and genotypic data. 16S rRNA gene sequence analysis revealed that the isolate belonged to the genus Devosia, with highest sequence similarity (98.5%) to Devosia riboflavina IFO 13584(T). Sequence similarities with other strains tested were below 97.0%. Strain GH2-10(T) had Q-10 as the predominant ubiquinone and C(18:1)w7c and C-16:0 as the major fatty acids. The G + C content of the genomic DNA was 59.5 mol%. The results of DNA-DNA hybridization experiments (47% relatedness between D. riboflavina DSM 7230(T) and strain GH2-10(T)) and physiological and biochemical tests suggested that strain GH2-10(T) represents a novel species of the genus Devosia, for which the name Devosia soli sp. nov. is proposed. The type strain is GH2-10(T) (= KACC 11509(T) =DSM 17780(T)).
