ABSTRACT

Spirulina plank tonic blue green algae are gaining increasing attention because of its nutritional and medicinal properties. The attempt of this work was to compare the antibacterial activity of Spirulina sp. isolated from Lonar Lake commercially available in Market. Organic solvents and aqueous extracts of Spirulina were prepared were identified and the extracts were evaluated for their antibacterial activities against Escherichia coli, Staphylococcus aureus, Salmonella typhi, Proteus vulgaris, Klebsiella pneumonia, and Pseudomonas aeruginosa by disc diffusion method. Methanol, ethanol, acetone and aqueous extracts of Spirulina platensis showed good antibacterial activity against Staphylococcus aureus, Salmonella typhi and Escherichia coli by both diffusion methods.

Keywords: Spirulina Platensis, Extraction process and Antibacterial activity.
