Abstract
In this study, totally thirty species of cyanobacteria belonging to twenty-two genera were isolated and identified from Vedaranyam coastal area. Among them cyanobacteria, Ocillatoria and Spirulina were tested in compliance with the agar well diffusion method for their antibacterial and antifungal agent production on human pathogens (Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, Aspergillus niger and Candida albicans). The antimicrobial activity was maintained by using different solvents (ethanol, chloroform, methanol and water). The present study exhibit maximum antimicrobial activity was recorded from methanol extracts of cyanobacterial species. The methanol extract of Oscillatoria formosa showed maximum inhibition against all the human pathogens than Spirulina subsalsa. Similarly bacterial pathogens were showed maximum inhibition when compared to fungal pathogens
