During a study to isolate such actinobacteria with unique metabolic potential, a novel actinobacterium, designated KC333T, was isolated from a soil sample collected from the Karakum Desert, Turkmenistan. The taxonomic position of the strain was investigated using a polyphasic approach. Phylogenetic analysis of the 16S rRNA gene sequence showed that the strain was most closely related to Nonomuraea terrae CH32T (99.0% sequence similarity), Nonomuraea maritima FXJ7.203 T (98.9%), Nonomuraea candida HMC10T (98.7%) and Nonomuraea gerenzanensis ATCC 39727 T (98.6%), and is therefore considered to represent a member of the genus Nonomuraea. However, the average nucleotide identity and digital DNA-DNA hybridization based on whole-genome sequences between strain KC333T and close relatives demonstrated that it represents a novel species of the genus Nonomuraea. The major cellular fatty acids of strain KC333T were iso-C16: 0, C17:0 10-methyl and iso-C16: 0 2OH. Strain KC333T contained meso-diaminopimelic, mannose, madurose and ribose in the cell-wall peptidoglycan. The predominant menaquinones were MK-9(H4) and MK-9(H6). The genome size of strain KC333T is approximately 9.86 Mb, and the genomic DNA G + C content of the strain is 71.3%. In addition to the polyphasic characterisation, comprehensive genome analysis for gene clusters encoding carbohydrate-active enzymes and bioactive secondary metabolites as well as CRISPR-associated sequences revealed the high biotechnological potential of the strain. Based on evidence collected from the genotypic, phenotypic, and phylogenetic analyses, a novel species, Nonomuraea aridisoli sp. nov. is proposed with KC333T (= DSM 107062 T = JCM 32584 T = KCTC 49111 T) as the type strain.
