Transfer of Actinoplanes armeniacus Kalakoutskii and Kusnetsov to Streptomyces: Streptomyces armeniacus (Kalakoutskii and Kusnetsov) comb. nov.

Abstract
A study was made of the morphology, cell wall chemotype and phage susceptibility of A. armeniacus ATCC 15676, the type strain of the species. The spore chains produced by A. armeniacus on its aerial mycelium are similar to those typical of streptomycetes. No spore vesicles (sporangia) were observed. Whole-cell hydrolysates contained LL-diaminopimelic acid. Phage activity spectra showed extensive cross-reactions between streptomycetes and A. armeniacus ATCC 15676, where as phage propagated on this strain lysed a range of Streptomyces spp. On the basis of these characteristics, the transfer of A. armeniacus Kalakoutskii and Kusnetsov to the genus Streptomyces is proposed as S. armeniacus (Kalakoutskii and Kusnetsov) comb. nov. The type strain of this taxon is ATCC 15676. An amended description of this species is given.
