Article Info		Abstract
Received: 02-08-2016 Revised: 26-09-2016 Accepted: 29-09-2016		The research work investigates the in-vitro antimicrobial efficacy of lichen Ramalina conduplicans Vain. (Ramalinaceae). The 2-Propanol, methanol, acetone and petroleum ether extract of the species were tested each against eleven bacterial and fungal pathogens by using Kirby-Bauer disc diffusion method with 15 μL extract per disc. It is observed that the extracts are effective against bacteria in than to the fungi. Among various extracts methanol was much effective against most of the bacteria and diameter of inhibition zone ranged from 12.66±0.66 to 16.66±1.6 mm. In case of antifungal activity the extract formed zone of inhibition against only six pathogens. The R. conduplicans can be a potential source of bioactive agents against disease causing microbes of humans and plants.
Keywords: Antifungal, antibacterial, Kirby-Bauer disc diffusion assay, bioprospecting, lichenized fungi.
