We researched microscopic morphological characteristics of Streptomyces coelicolor(REINER-MULLER) BERGEY et al. ATCC 10147,IFO 3176.The aerial mycelia are well developed and branch in monopodial forms : occasionally two or more branches grow from the same place on the main hyphae. The primary branches may function directly as sporogenous hyphae or may produce branches of the second and higher orders. Terminal branches are often arranged in cluster. The terminal hyphae have many spirals and wavy hyphae; the curvature of spirals are dextrorse under the microscope, extended or comparatively compact, 1〜6 turns, 3,2〜4.8μ in diameter.Sporogenesis is confined to the terminal elements, and the hyphal portions below the points of attachments of branches remain sterile.The aerial hyphae have a diameter of 0.9〜1.3μ, and no septa.The spores (oidia) are oval or long oval; 0.9〜1.3 by 1.0〜1.6μ.
