Conditions for microcycle sporogenesis in two streptomycete strains without shifting the culture were found. The sporulation in Streptomyces granaticolor took place after 24 h of cultivation. The dry mass was increasing till 32 h probably due to production of a hydrophobic substance resembling fibrous sheath of aerial hyphae and spores. Ultrathin section of microcycle spores are presented.
