A polyphasic approach was used to establish the taxonomic position of two actinomycetes isolated from a Namibian soil and shown to utilise nitrile compounds as growth substrates. The organisms, strains NAM-BN063AT and NAM-BN063B, had chemical and morphological properties consistent with their assignment to the genus Gordonia. Direct 16S rRNA sequencing studies confirmed the taxonomic position of the strains following the generation of phylogenetic trees using four different algorithms. The strains consistently formed a distinct phylogenetic line within the evolutionary radiation occupied by gordoniae and were most closely related to Gordonia rubropertincta DSM 43197T. DNA:DNA relatedness studies indicated that the two organisms belonged to a genomic species that was readily distinguished from G. rubropertincta. The unique phenotypic profile of the strains sharply separated them from representatives of all of the validly described species of Gordonia. The combination of genotypic and phenotypic data indicates that the two strains should be classified in the genus Gordonia as a new species. The name proposed for this taxon is Gordonia namibiensis, the type strain is NAM-BN063AT (= DSM 44568T = NCIMB 13780T).
