Abstract: AIM: The spread of multidrug-resistant strains of bacteria makes it necessary to discover new classes of
antibacterial and compounds that inhibit these resistant mechanisms. Hence, this study was conducted to
evaluate the antimicrobial activities of Lenzites betulinus and Coriolopsis gallica extracts against some
bacterial isolates of medical importance.
METHOD: The organisms are Pseudomonas aeruginosa, Staphylococcus aureus, Proteus vulgaris,
Klebsiella pneumoniae, Escherichia coli. Using agar well diffusion assay, the ethanolic, petroleum ether
and aqueous extract of C. gallica was assayed against the bacterial isolates and the result showed that
Petroleum ether extract of C. gallica and L. betulinus was able to inhibit P. vulgaris with inhibition
zones of 26.0 mm and 20.0 mm respectively.
RESULTS: Ethanolic extract of C. gallica also inhibited P. vulgaris with inhibition zone of 22.0 mm
while aqueous extract and petroleum ether of L. betulinus inhibited P. aeruginosa with inhibition zones
of 20.0 mm and 23.0 mm respectively. E. coli and S. aureus were also inhibited by the aqueous and
ethanolic extract of L. betulinus with zones of inhibition 15.0 mm and 26.0 mm against E. coli while
19.0 mm and 22.0 mm against S. aureus respectively. This study also showed the presence of some
phytochemicals like tannins, phenolics, flavonoids, steroids, and saponin in the mushrooms with
antimicrobial effects against the bacterial isolates used.
CONCLUSION: The active components present in ethanolic, aqueous and petroleum ether extracts of
C. gallica include phenolics, flavonoids, and steroids while phytochemicals obtained from L. betulinus
are phenolics, tannins, flavonoids, and saponin respectively.
