ASSAY OF ANTIBIOTIC PRODUCING MICROORGANISMS ISOLATED FROM DIFFERENT SOILS IN THE PREMISES OF FEDERAL UNIVERSITY OYE-EKITI

Abstract

A total of eight soil samples were collected from different sites within FUOYE environment and were analysed to determine the presence of antibiotic producing bacteria, fungi and actinomycete using Nutrient agar, Sabauraud dextrose agar and Glycerol yeast extract agar as culture media. Seven bacteria: Escherichia coli, Bacillus spp, Pseudomonas spp, Azomonas spp, Gluconobacter spp, Micrococcus spp, and Staphylococcus aureus; five fungi: Rhizopus spp, Mucor spp, Rhodotorula app, Trichoderma spp, Aspergillus spp and one actinomycete: Actinomyces humiferus were isolated. These isolates were screened for their antimiocrobial potency against selected reference pathogenic organisms: Staphylococcus aureus, Pseudomonas aerugenosa, and Candida albicans. Bacillus spp isolated was found to inhibit Staphylococcus aureus and Pseudomonas aerugenosa, Actinomyces spp inhibited all the pathogens at different rate, fungal isolate, Rhizopus spp inhibited Staphylococcus aureus while the other fugal isolate did not inhibit any of the reference pathogens.
