The plant material was subjected to an extraction process with solvents like chloroform, methanol and water. The results showed that all solvent extracts of C. citratus exhibited maximum zone of inhibition against B. subtilis,P. aeruginosa and P. vulgaris. All solvent extracts of lemongrass plant exhibited minimum inhibition activity against Nocardia sp., E. aerogenes, Serratia sp., and S.aureus. Zone of inhibitions are shown in Tables 1 to 3. It was observed that antibacterial activity of C. citratus plant leaf extracts showed good results for Gram-positive and Gramnegative organisms.
