Study on antimicrobial activity of various extracts of saxicolous lichen Lecanora Muralis

Abstract

Antimicrobial activity of aqueous, acetone, methanol, and ethanol extracts of saxicolous lichen Lecanora muralis sampled from Odzun, Lori province of Armenia were studied. Aqueous extract was not demonstrated any significant antibacterial activity neither Gram positive nor Gram negative bacteria. All other extracts exhibited antimicrobial activity only against only tested Grampositive bacteria. The minimal inhibitory concentration (MIC) value of acetone extract was 57 μg/μl against Bacillus subtilis.
