title: Microvirga soli sp. nov., an alphaproteobacterium isolated from soil.
abstract: An aerobic, Gram-stain-negative, catalase-positive and oxidase-negative, non-motile, non-spore-forming, rod-shaped, pink-pigmented bacterium designated strain R491T was isolated from soil. Flexirubin-type pigments were absent. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain R491T formed a lineage within the family Methylobacteriaceae of the phylum Proteobacteria that was distinct from various species of the genus Microvirga, including Microvirgaaerilata 5420S-16T (97.83 % 16S rRNA gene sequence similarity), Microvirga zambiensis WSM3693T (97.76 %), Microvirga flocculans ATCC BAA-817T (97.41 %), and Microvirga lupini Lut6T, Microvirga subterranea DSM 14364T, Microvirga vignae BR3299T, and Microvirga guangxiensis 25BT (96.99 %). The major polar lipids of strain R491T were phosphatidylcholine, phosphatidylglycerol and phosphatidylethanolamine. The major cellular fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c; 71.2 %), C16 : 0 (12.0 %), summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 4.7 %), and C18 : 0 (4.2 %). The DNA G+C content of strain R491T was 61.8 mol%. DNA-DNA hybridization values between strain R491T and other members of the genus Microvirga ranged from 27 to 57 %. On the basis of phenotypic, genotypic and phylogenetic analyses, strain R491T represents a novel species of the genus Microvirga, for which the name Microvirga soli sp. nov. is proposed. The type strain is R491T (=KEMB 9005-408T=KACC 18969T=NBRC 112417T).
