The taxonomic position of a strain isolated from soil in Shiraz, Fars province, Iran, was investigated. Strain UTMC 693T produced an extensively branched substrate mycelium and aerial hyphae consisting of hyphae that fragment into short to elongated rod-like elements. The chemotaxonomic characteristics of the isolate matched those described for the genus Kribbella . Strain UTMC 693T showed the highest 16S rRNA gene sequence similarity to Kribbella karoonensis DSM 17344T (98.3 %), K. swartbergensis DSM 17345T (98.2 %), K. hippodromi S1.4T (98.0 %), K. aluminosa HKI 0478T (98.0 %) and K. jejuensis HD9T (98.0 %). DNA–DNA hybridization studies with closely related type strains showed 56.3 % relatedness to K. karoonensis , 21.3 % to K. swartbergensis , 39.0 % to K. jejuensis and 42.0 % to K. aluminosa . Thus, strain UTMC 693T can be considered to represent a novel Kribbella species. Strain UTMC 693T showed the typical morphology found among members of Kribbella , but can be differentiated easily from closely related species by genotypic characteristics, chemotaxonomic results and other phenotypic markers. Based on these results, strain UTMC 693T ( = DSM 45490T = CCUG 61792T) is considered the type strain of a novel species of the genus Kribbella , for which the name Kribbella shirazensis sp. nov. is proposed.
