In Vitro Antimicrobial Activity Analysis Of Lemon Grass Leaf Extracts Against Pathogenic Bacteria

Lemongrass is used to treat fever, fatigue, convulsions, common cold, rheumatism, vomiting, convulsions, discomfort, and digestive system spasms. The present investigation was performed to investigate the antibacterial property of methnolic, acetone and benzene extract of lemon grass against pathogenic bacteria. The maximum inhibition zone for methanol extract was Pseudomonas aeruginosa and Staphylococcus aureus (18 mm) at a concentration of 100 mu l/ml. Benzene extract also exhibited a 17 mm zone at 100 mu l/ml against bacteria- Pseudomonas aeruginosa. Behind it, 50 mu l/ml of methanol extract exhibited 16 mm of Pseudomonas aeruginosa and 100 mu l/ml of benzene extract against Klebsella pneumoneae. As concentration increases against all bacteria, the anti-bacterial activity of extracts increases. Among all the extracts methanol extract have been found more potential extract for antibacterial as well as lowest MIC. So lemon grass can be used to treat many bacterial diseases.
