  • Introduction: Secondary metabolites are organic compounds produced by any lifeform, e.g. bacteria, fungi or plants, which are not directly involved in the normal growth, development, or reproduction of the organism. These compounds have been used because of its antimicrobial effects.
  • Methods: In this study secondary metabolites of Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Acreomonum spp. and penicillium spp. isolated from moldy Livestock ration and its antimicrobial properties against of Escherichia coli (ATCC 25922) was investigated.
  • Results: Results of this study showed that the Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Acreomonum spp MIC was 250 (µl/ml) and the MBC was 500 (µl/ml).
  • Conclusion: Based on the results; secondary metabolites of Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Acreomonum spp. had the antibacterial effects on Escherichia coli and can able be newest antimicrobial agent against this microorganism.
  • Keywords: Secondary metabolites, Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Acreomonum spp.
