Identification and characterization of Streptomyces strain Caat 8-25 metabolites as a potential bioherbicide

Herbicidins are described in the literature as being herbicidal activity2 and to test this fact we submitted the liquid culture media of both strains, to a germination bioassaw with lettuce, arugula and grass seeds.
From the bioassay, we found out that all seeds in presence only of water and the fermentation broth of Streptomyces rimosus germinated, however in the presence of CAAT 8-25 fermentation broth there was no germination.
