Antimicrobial Activity of Citrullus Colocynthis Extracts Against Soil Bacteria
Abdullah S. Alshammary ,Nasir.A Ibrahim
The study aim to evaluate the ability of Citrullus colocynthis, to reducing soil microbial load. To prepared extractes using water, ethanol and chloroform as solvent. The extracts concentration 0.001, 0.001 and 0.1mg/l and were subjected to preliminary phyotochemical screening and tested against the gram negative and positive rhizosphere bacteria by disc diffusion. Among these extracts the chloroform was found to be most effective in all three strains. Maximum inhibition zone was 15.6mm, and minimum inhibition zone was 9.1mm when ethanol extract was followed by the activities of extracts of three strains. Maximum inhibition zone was 14 mm and minimum inhibition zone was 8.8 mm. The water aqueous extract was less activity against tested organisms.
