[Morphology of Streptomyces chrysomallus microcolonies in submerged cultivating].
Gel matrix covering microcolonies and individual hyfs and cords of mycelial hyfs was for the first type detected using a special method for making preparations for microscopic examinations. The matrix is observed during culturing streptomycetes in media of different composition for mycelium of different age. Gel matrix renders the colonies a compact shape and can be regarded as a specific structural component of Streptomyces microcolonies. The matrix contains gels differing by hydrophobicity and low-molecular-weight biosynthesis products, including actinomycin antibiotics, which play an important role in maintenance of morphological structure.
