Abstract SYP-B2174T is a yellow-pigmented, Gram-positive, non-motile, and rod-shaped actinobacterium isolated from the rhizospheric soil of Aquilegia viridiflora Pall. collected from the Xinjiang uygur autonomous region of China. The strain's growth temperature ranges from 1 to 35°C, with an optimal growth being observed at 28°C. Growth occurs from 0 to 5% NaCl and at pH 6-8, with optimal growth being observed in 1% NaCl at pH 7. Comparative 16S rRNA gene sequence-based phylogenetic analysis placed the strain in a clade with the species Leifsonia kafniensis JCM 17021T and Leifsonia psychrotolerans DSM 22824T with similarities of 97.8 and 97.6%, respectively. The DNA-DNA hybridization values of the strain SYP-B2174T to its closest phylogenetic neighbors were significantly lower than 35.7%. The strain was identified as a novel species of the genus Leifsonia judging by the coryneform morphology, peptidoglycans based upon 2,4-diaminobutyric acid, principal phospholipids phosphatidylglycerol and diphosphatidylglycerol, major menaquinone MK-11, predominant fatty acids of anteiso-C15:0, anteiso-C17:0, and iso-C16:0, and a DNA G + C base composition of 68.7 mol%, for which the name Leifsonia flava sp. nov. is proposed. The type strain is SYP-B2174T (= CGMCC 1.15856T = DSM 105144T = KCTC 39963T).
