摘要： An aerobic, Gram-stain-positive actinomycete, designated strain 3SM4-07(T), was characterized using a polyphasic taxonomic approach. The strain produced branching mycelium which fragmented into short or elongated rods. The whole-cell hydrolysates contained LL-2,6-diaminopimelic acid as the diagnostic diamino acid, with glucose and ribose as the main sugars. The predominant cellular fatty acids were anteiso-C-15:0, iso-C-15:0 and iso-C-16:0. The predominant menaquinone was MK-9(H-4). Phospholipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylinositol and phosphatidylinositol mannoside. Mycolic acids were absent. The DNA G+C content was 72.3 mol%. Strain 3SM4-07(T) formed a phylogenetic line within the genus Jiangefla and its 16S rRNA gene sequence was related most closely to Jiangella alkaliphila D8-87(T) (99.0 % similarity), Jiangella muralis 15-Je-017(T) (98.8 %), Jiangella alba YIM 61503(T) (98.6 %) and Jiangella gansuensis YIM 002(T) (98.6 %). However, mean DNA-DNA hybridization values. revealed that strain 3SM4-07(T) differed from the closest species previously described in this genus. Data from phenotypic, chemotaxonomic and molecular analyses between strain 3SM4-07(T) and recognized species of the genus Jiangella indicate that strain 3SM4-07(T) is a representative of a novel species of the genus Jiangella, for which the name Jiangefla mangrovi sp. nov. is proposed. The type strain is 3SM4-07(T) (=BCC 60398(T)=NBRC 109648(T)).
