More than 1,50,000 macro algae or seaweed species are found in oceans of the globe, but only a few of them were identified [1]. Secondary or primary metabolites from these organisms may be potential bioactive compounds of interest for the pharmacological industry [2]. Special attention has been reported for antiviral,
antibacterial and antifungal activities related to marine algae against several pathogens [3]. The antimicrobial compounds derived from the marine floraconsist of diverse groups of chemical compounds [4]. The cell extracts and active constituents of various algae have been shown to have antibacterial activity against Gram positive and Gram negative bacteria [5].
