Analysis of its 16S rRNA gene sequence and construction of a phylogenetic tree showed most similarity to <jats:italic>Amycolatopsis kentuckyensis<\/jats:italic> NRRL B-24129<jats:sup>T<\/jats:sup>, <jats:italic>Amycolatopsis lexingtonensis<\/jats:italic> NRRL B-24129<jats:sup>T<\/jats:sup> and <jats:italic>Amycolatopsis pretoriensis<\/jats:italic> NRRL B-24133<jats:sup>T<\/jats:sup>, but the strain was probably not a member of any of these species. Results from DNA\u2013DNA hybridization experiments and comparison of DNA profiling patterns using pulsed-field gel electrophoresis also supported the assignment of strain DSM 46095 to a novel species. Analyses of phospholipids, fatty acid methyl esters and physiological characteristics also showed that the differences between different isolates of <jats:italic>A. mediterranei<\/jats:italic> and <jats:italic>A. mediterranei<\/jats:italic> DSM 46095 were as large as those between <jats:italic>Amycolatopsis<\/jats:italic> species.
