Evaluation of antibacterial potential of an invasive grass (Arundo donax L.) in a lower Siwalik Region, India.


Arundo donax L. is a potent invasive weed of aquatic and moist areas distributed worldwide ranging from subtropical low lying hills to warm temperate regions. Despite this, it has a large number of economical applications such as bioenergy production, paper and cellulose production, musical instruments and other household purposes. For medicinal purposes, used as a household remedy for the treatment of various ailments. However, its efficacy against human pathogens is lesserknown. Therefore, we designed to explore in this study to analyze its antibacterial activity against various isolates of bacterial strains. Results indicated that the methanolic root extract showed maximum antibacterial activity against Pseudomonas aeruginosa strain (15.0 ± 2.8) at a concentration of 40 ug/ml, while methanolic leaf extract revealed maximum activity against the strain of Streptococcus aureus (7.33 ± 3.7) at the same level of concentration. No antibacterial activity was observed against Bacillus sp. and Escherichia coli. While in the case of methanolic extract of the leaf; Bacillus sp. was totally unaffected by the extract concentration. This antibacterial activity can be beneficial by investigating secondary metabolites at ground level for developing new medicines. Therefore, comprehensive studies at a broader scale by considering different concentrations of the extract against several other human pathogens can also be another window to open for exploration on account of harnessing its antibacterial potential.
