Abstract

Activities of the distilled water, ethanolic and chloroform extracts of Daldina concentrica check for this species in other resources an ascomycetous fungus was investigated on Escherichia coli check for this species in other resources , Proteus mirabilis check for this species in other resources , Pseudomonas aeruginosa check for this species in other resources , Bacillus cereus check for this species in other resources and Staphylococcus aureus check for this species in other resources ) using agar well diffusion method. Ethanolic extract of Daldina concentrica showed significantly antibacterial activity against all the test microorganisms except Bacilllus cereus (P ≤0.05). Staphylococcus aureus was the most sensitive organism to the extracts of this fungus with 17.0mm zone of inhibition with ethanol extract. It was also shown that chloroform extract of Daldinia concentrica possessed higher anti-bacterial activity against the five tested microorganisms. The effect of fresh tissues of the fungus on test bacteria indicated that Proteus mirabilis was the only sensitive organism with 5.0mm zone of inhibition while other bacteria were resistant. The implications of these findings were discussed.
