ABSTRACT
In vitro antimicrobial activity of two selected marine macroalgae has been evaluated in the present research, which lies in identifying certain seaweeds whose extract can act as an alternative to commonly used antibiotics hence possessing activity against human pathogens. Extract from two species of seaweed samples namely Caulerpa racemosa and Grateloupia lithophila were collected from different locations at Gulf of Mannar, Southeast Coastal Region, M andapam, Tamil Nadu, India and w ere screened for antimicrobial activity. Extracts of Methanol, Ethanol, Butanol, Acetone, Chloroform and Dichloromethane were tested against selected human pathogens. Both the seaweeds collected had shown moderate antibacterial activity with
