Biological Effects OF Certain Streptomycin Metabolites ON Some Toxic Cyan Bacteria

The present work involves the study of the biological effects of cetain Streptomyces metabolites on some toxic cyanobacteria, 107 Streptomyete cultures were isolated from several soil samples collected from cultivated lands form El-Sharkia province; El-Da2- The detailed study of their antimicrcbial characteristics of these organisms was studied against some blue green algae and the present results revealed that, the isolates No. 40 & 60 are the best isolates which have maximum inhibitory effect on growth
