| Summary: | © 2015 IUMS. An aerobic, Gram-stain-positive actinomycete, designated strain 3SM4-07 < sup > T < /sup > , 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 < inf > 15: 0 < /inf > , iso-C < inf > 15: 0 < /inf > and iso- < inf > C16: 0 < /inf > . The predominant menaquinone was MK-9(H < inf > 4 < /inf > ). 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 < sup > T < /sup > formed a phylogenetic line within the genus Jiangella and its 16S rRNA gene sequence was related most closely to Jiangella alkaliphila D8-87T (99.0% similarity), Jiangella muralis 15-Je-01 7 < sup > T < /sup > (98.8%), Jiangella alba YIM 61503 < sup > T < /sup > (98.6%) and Jiangella gansuensis YIM 002 < sup > T < /sup > (98.6%). However, mean DNA-DNA hybridization values revealed that strain 3SM4-07 < sup > T < /sup > differed from the closest species previously described in this genus. Data from phenotypic, chemotaxonomic and molecular analyses between strain 3SM4-07 < sup > T < /sup > andrecognizedspecies of the genus Jiangella indicate that strain 3SM4-07 < sup > T < /sup > is a representative of a novel species of the genus Jiangella, for which the name Jiangella mangrovi sp. nov. is proposed. The type strain is 3SM4-07 < sup > T < /sup > (=BCC 60398 < sup > T < /sup > =NBRC 109648 < sup > T < /sup > ). |
