EFFECT OF TEMPERATURE AND PH ON ANTIBACTERIAL ACTIVITY OF PLANT EXTRACT (MURRAYA KOENGII) IN SOME SELECTED SOLVENT FOR SOME SELECTED BACTERIA

Shailendra Yadav, Nahid Usmani Mirza

Abstract :

The basic aim of the present study to evaluate the antimicrobial activity of Murraya koengii plant extract (root, leave, bark)at different pH and temperature for bacterial species E. coli, K. pneumoniae and Rizobium. Antibacterial activity of acetone extract expressed a slight increment with increment in PH (basic medium) for E.coli, while in case of K. pneumoniae and Rhizobium, increment in antibacterial activity found at low pH (acidic medium). In ethanol extract as the acidity increased, there was a slight increase in zone of inhibition for all three species .water extract did not give more specific result, antibacterial activity of water ,ethanol, and acetone extracts were stable at high temperature[70˚c,100˚c]..
