Amycolatopsis decaplanina sp. nov., a novel member of the genus with unusual morphology.

Strain DSM 44594T, which produces the glycopeptide antibiotic decaplanin, is a member of the genus Amycolatopsis based on 16S rRNA gene sequence analysis and chemotaxonomic properties. It is the first member of this genus that is reported to form pseudosporangia, which resemble those of members of the genus Kibdelosporangium. Phylogenetically, the novel taxon is related to Amycolatopsis orientalis, Amycolatopsis lurida, Amycolatopsis azurea, Amycolatopsis japonica and Amycolatopsis keratiniphila. Morphological, cultural and physiological properties, the production of a unique glycolipid and DNA-DNA similarity of <55% with phylogenetically related strains reveal that strain DSM 44594T represents a novel species of the genus, for which the name Amycolatopsis decaplanina sp. nov. (type strain, FH 1845T=DSM 44594T=NRRL B-24209T) is proposed.
