Antifungal Properties of Streptomyces sp. against Aflatoxin Producing Aspergillus Species
Medha Jyoti, Dr. Archana Kumari
Abstract: The streptomyces tendae isolated from all five soil samples obtained from different locations of Gaya district exhibited antifungal activity against aflatoxin producing Aspergillus flavus and Aspergillus parasiticus, when examined after application of cell-free supernatant of Streptomyces sp. The cell-free supernatant concentrioin of Streptomyces tendae from 0.5% to 20% gradually increased the inhibitory action against both types of aflatoxin producing fungal species examined during present research work. Inhibition of fungal growth was achieved at optimum level after application of 20% concentration of cell-free supernatant of this bacteria. However, cell-free supernatant of this bacteria remained most effective against Aspergillus flavus as compared to Aspergillus parariticus. Hexa hydro 3-3 methyl propyle-2, H-4, 4-diazepin remained most effective against both types of aflatoxin producing species of Aspergillus at 26-27 ?g/ml as minimum inhibitory concentration.4-(4 hydroxy pheny)-2-butanon remain least effective against both types of aflatoxin producing species of Aspergillus because minimum inhibitory concentration of this bioactive compound was observed as 92-89 ?g/ml. However, all seven types of secondary metabolites showed inhibitory action against Aspergillus flavus and Aspergillus parariticus.
