This research work is to investigate the antifungal potential of actinomycetes isolated from five different sources against Aspergillus flavus and Fusarium verticillioides. Isolation of microorganisms from the soil samples was carried out by serial dilution and pour plate techniques. The soil isolates were screened for their antagonistic ability against mycotoxigenic fungi: A. flavus and F. verticillioides. The isolates include Actinomyces spp, Mycobacterium spp, Rhodococcus spp, Nocardia spp, Streptomyces spp, and Streptomonospora spp. The results indicate that all the bacteria species exhibited varying degrees of biological control potential against the tested fungi. Out of all the actinomycetes use, Streptomyces spp appeared to have the highest diameter zone of inhibition against A. flavus of 16.00 mm and against F. verticillioides of 21.00 mm. The results showed the antimicrobial activity of the actinomycetes species, and thus indicate the potential of using them as bio-fungicidal agents in reducing the damages and threat caused by A. flavus and F. verticillioides in crop production.
