The present study investigated the antibacterial activity of methanol extracts of the leaves of Lemna minor (Lemnaceae) against eight different bacterial species such as Bacillus subtilis, Escherichi coli, Pseudomonas aeruginosa, Staphylococcus aureus, Micrococcus luteus, Shigella flexneri, Bacillus megaterium and Salmonella typhi using resazurin microtiter plate assay and colorimetric resazurin assay. The methanol extract of the leaves showed antibacterial activity against maximum number of bacterial species in the present study the least minimum inhibitory concentration (MIC) value of 12.0 ïg/ml of methanolic extract of the leaves of Lemna minor was recorded against the bacterium species
