| Abstract | ||
| The aim of present study is to investigate the antagonistic activity of Spirogyra micropunctata against multidrug resistant human pathogens. The test organisms include 3 Gram negative bacteria such as Echerichia coli, Klebsiella pneumoniae, Salmonella typhi and 2 Gram positive bacteria such as Staphylococcus aureus and Staphylococcus epidermidis. The algal cell mass was extracted in 90% Methanol and 90% Ethanol and further concentrations of 0.5, 1, 3, 5, 10, 20 mg/ml were made for each extract. Antagonistic effect was tested by using agar well-diffusion method. Methanolic crude extract showed strong antibacterial activity against all tested bacteria, while ethanolic crude extract showed moderate activity. These findings suggest the possibility of using the Spirogyra micropunctata as a novel source of natural antimicrobial agents in pharmaceutical industries. | ||
