Antimicrobial Activity of Dicoma tomentosa Plant in arid region of Jhunjhunu

The resistance of pathogenic bacteria and fungus strains to antibiotics is the major burning issue around the world. To minimize the strain resistance to antibiotics plant Dicoma tomentosa was selected. In the present study, the leaves and stem of Dicoma tomentosa was collected and antimicrobial activity was examined through Agar well diffusion method. The crude extracts were obtained by using methanol extraction solvent. Antimicrobial activity of leaves and stem extracts of Dicoma tomentosa was evaluated hostile four fungus Penicillium funiculosum, Aspergillus Niger, Trichoderma ressei and Fusarium oxysporum and four bacterial strains, Staphylococcus aureus, Streptomyces grisveus, Escherichia coli and Bacillus subtilis. It was determined that maximum zone of inhibition was in leaves (12mm) against bacillus subtills In fungus, maximum zone was observed in stem against Trichoderma ressei (13mm) while other fungal colonies were found to be resistant.
