Nonomuraea jiangxiensis sp. nov., isolated from acidic soil.

An actinomycete, designated FXJ1.102(T), was isolated from acidic soil collected in Jiangxi Province, south-east China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain FXJ1.102(T) belonged to the genus Nonomuraea and was most closely related to Nonomuraea candida HMC10(T), Nonomuraea turkmeniaca DSM 43926(T), Nonomuraea antimicrobica YIM 61105(T) and 'Nonomuraea aegyptia' S136 (98.9, 98.3, 97.9 and 97.5 % 16S rRNA gene sequence similarities, respectively). The morphological characteristics were typical of the genus Nonomuraea. The chemotaxonomic properties, such as cell-wall chemotype IIIB, phospholipid type IV, MK-9(H(4)) as the major menaquinone and iso-C(16:0) (22.2 %) as the major fatty acid, supported the assignment of the strain to the genus Nonomuraea. DNA-DNA relatedness and physiological tests allowed genotypic and phenotypic differentiation of strain FXJ1.102(T) from its closest phylogenetic relatives. The isolate therefore represents a novel species, for which the name Nonomuraea jiangxiensis sp. nov. is proposed. The type strain is FXJ1.102(T) ( = CGMCC 4.6533(T) = NBRC 106679(T)).
