A straight-chain, spore-forming actinobacterium, strain YIM 120770T, was isolated from soil. Phylogenetic analysis on the basis of 16S rRNA gene sequence comparisons revealed that the isolate represents a distinct cluster within the clade comprising the genus Nonomuraea and is related most closely to Nonomuraea rhizophila YIM 67092T (96.5 % similarity). Cells of strain YIM 120770T grew in the presence of 0–3 % (w/v) NaCl, at 15–37 6C and at pH 7.0–8.0. The diagnostic amino acid was meso-diaminopimelic acid, cell hydrolysates contained madurose, glucose, mannose, ribose and galactose, the predominant cellular fatty acids were 10-methyl C17: 0 and iso-C16: 0, and the DNA G+C content was 66.4 mol%, data consistent with affiliation of strain YIM 120770T to the genus Nonomuraea. Strain YIM 120770T shared low levels of 16S rRNA gene sequence similarity (,97%) with the type strains of recognized species of the genus Nonomuraea and could be differentiated from its closest phylogenetic relative based on phenotypic characteristics. These results suggested that strain YIM 120770T represents a novel species of the genus Nonomuraea, for which the name Nonomuraea soli sp. nov. is proposed. The type strain is YIM 120770T (5DSM 45533T5JCM 17347T). The etymology of the genus Nonomuraea was corrected by Chiba et al. (1999) following description of the genus Nonomuria by Zhang et al. (1998). At the time of writing, the genus comprised 26 recognized species and two subspecie
