| Popis: | A novel bacterial strain, designated THG-RS2OT, was isolated from fallow-land soil previously cultivated with Brassica oleracea in Yongin, South Korea. Cells were Gram-stain-negative, aerobic, non-motile rods, catalase- and oxidase-positive. Strain THG-RS2OT grew optimally at 25–37 °C, at pH 7.0 and in the absence of NaCl. 16S rRNA gene sequence analysis demonstrated that strain THG-RS2OT shows highest sequence similarity with Massilia kyonggiensis KACC 17471T followed by Massilia aerilata KACC 12505T, Massilia niastensis KACC 12599T, Massilia tieshanensis KACC 14940T and Massilia haematophila KCTC 32001T. Levels of DNA–DNA relatedness between strain THG-RS2OT and the closest phylogenetic neighbours were below 55.0 % and the DNA G+C content of strain THG-RS2OT was 63.2 mol%. Major fatty acids were C16 : 0, cyclo-C17 : 0 and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c). The major respiratory quinone was identified as ubiquonone-8 and predominant polar lipids were determined to be diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. Characterization by 16S rRNA gene sequence analysis, DNA–DNA hybridization, ubiquinone, polar lipid, fatty acid composition, and physiological and biochemical parameters revealed that strain THG-RS2OT represents a novel species of the genus Massilia. Hence, the present study describes a novel species for which the name Massilia arvi sp. nov. is proposed. The type strain is THG-RS2OT ( = KCTC 42609T = CCTCC AB 2015115T). |
