Occurrence of polysaccharide granules in sporulating hyphae of Streptomyces viridochromogenes. 1980

A F Braña, and M B Manzanal, and C Hardisson

Evidence of the presence of polysaccharide polymers is shown in Streptomyces sp. for the first time. Cytochemical methods revealed the occurrence of polysaccharide granules in sporulating hyphae of Streptomyces viridochromogenes. Onset of the sporogenesis coincided with the appearance of the granules, which reached a maximum number during the early stages of maturation. The later stages of maturation showed a decrease of these granules, and in mature spores no granules were observed.
