Eurihaline microalgae - a novel substance against post operative pathogen

Abstract: 

Objective: To evaluate the antibacterial activity of two saltpan microalgae Amphora sp and Oscillatoria sp against post operative pathogens Methods: Samples of microalgae were collected from the puthalam solar saltpan of Kanyakumari district. Two microalgae Amphora sp and Oscillatoria sp were identified and isolated by serial dilution method. Biomass was produced by culturing the isolated strains in one litre of Walne’s medium. The activity was assessed by using ethanol and petroleum ether solvents. The post operative pathogens such as Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris and Staphylococcus aureus were chosen for the present antibacterial susceptibility study. The extracts were tested in compliance with disc diffusion method for their antibacterial activity. Results: The results showed that the highest zone of inhibition were observed in Amphora sp against E.coli in ethanol extract and in Oscillatoria sp highest zone of inhibition were observed in ethanol extract against Staphylococcus aureus. Maximum antibacterial activity were observed in ethanol extracts than petroleum ether extracts. Conclusion: This result proved that saltpan microalgae possess antibacterial activity therefore, this microalgae is used to treat post operative pathogenic bacteria.
