Possible role of streptomycin released from spore cell wall of Streptomyces griseus.
Vegetative mycelia and spores of the investigated high- and low-producer strains of Streptomyces griseus bound significant amounts (4%) of streptomycin, which could be removed by increasing ionic strength. The release of antibiotic from the spores was easier when the spores were germinating. This phenomenon is considered to play an ecological role. We suppose that the streptomycin released during the germination process may protect the young hyphae from the different bacteria growing in the microenvironment of the Streptomyces spores.
