A wild-type strain of Streptomyces griseus forms spores both on solid media (aerial spores) and in liquid culture (submerged spores). Both spore types are highly resistant to sonication, but only aerial spores are resistant to lysozyme digestion. Electron micrographs suggest that lysozyme sensitivity may result from the thinner walls of the submerged spores. Studies of the life cycle indicate that neither streptomycin excretion nor extracellular protease activity is required for sporulation… CONTINUE READING
