摘要： A novel actinomycete, strain W6(T), was isolated from a soil sample of Yunnan Province, China. The bacterium was aerobic, non-motile, non-spore-forming and Gram-stain-positive. Genetic, phenotypic and chemical properties of the isolate were studied. 16S rRNA gene sequence data suggested that the novel isolate belonged to the genus Friedmanniella and shared 98.6% sequence similarity with Friedmanniella antarctica DSM 11053(T) and Friedmanniella okinawensis DSM 21744(T), the most closely related species. The cell-wall peptidoglycan contained LL-diaminopimelic acid, and mycolic acids were absent. The main menaquinone was MK-9(H-4) and the predominant fatty acids were anteiso-C-15:0 and iso-C-15:0. The phospholipid profile contained phosphatidylglycerol, phosphatidylinositol, phosphatidylcholine and diphosphatidylglycerol. The DNA G+C content of strain W6(T) was 72 mol%. Strain W6(T) showed 30.0% and 28.5% DNA-DNA relatedness, respectively, to F. antarctica DSM 11053(T) and F. okinawensis DSM 21744(T). The combined genotypic and phenotypic data showed that strain W6(T) should be assigned to the genus Friedmanniella as a representative of a novel species, for which the name Friedmanniella flava sp. nov. is proposed. The type strain is W6(T) (=CGMCC 4.6856(T)=JCM 17701(T)).
