  • Title: [New elementary structures of actinomycete spores of the genera Actinomadura and Streptomyces].
    Author: Soina VS, Agre NS.
    Journal: Mikrobiologiia; 1979; 48(1):90-2. PubMed ID: 423813.
    Abstract:
    The structure of spore surfaces was studied by electron microscopy in five species of actinomycetes, and two new types of elementary surface structures were discovered. The surface of spores in Streptomyces regensis consists of long flexible, closely interwoven, band-like structures 25 A wide. Ring-like structures 140--150 A in diameter can be observed on spores of Actinomadura verrucosospora; their clusters resemble grapes and the spore silhouette looks like a cone. Rod-like structures of spores in Streptomyces cavourensis and Str. streptomycini which form an ornament resembling the surface of a basket and tubular strucutres in Str. acrimycini of which hair-shaped spore protrusions are made are similar to the elementary structures of spore surfaces in other actinomycetes.
