Abstract

Two actinomycete strains were isolated from within the fynbos-rich area surrounded by the horseracing track at Kenilworth Racecourse in Cape Town, South Africa. Rapid molecular identification indicated that the isolates belonged to the family . Based on 16S rRNA gene sequence analysis, the isolates were identified as members of the genus . Phylogenetic analysis showed that the isolates clustered with each other and were most closely related to DSM 43909. Further 16S rRNA gene sequence analysis using EzTaxon revealed that the isolates are closely related to TT1-11, MC5-1, LK2-10, DSM 43818 and DSM 43868. DNA–DNA hybridization and physiological tests allowed genotypic and phenotypic differentiation of both isolates from related species; however, their high DNA–DNA relatedness showed that they belong to the same genomic species. Strain Y22 ( = DSM 45644 = NRRL B-24859) was selected as the type strain to represent this novel species, for which the name sp. nov. is proposed.
