Abstract
The use of macro algaes in various industries has led researchers to a great deal of enthusiasm for spacious studies on anti-fungal, anti-bacterial, anti-viral, and anti-cancer properties. The present study was accomplished to determine the anti-bacterial and anti-oxidant activity of alginate and fucoidan extracted from brown algae (S. boveanum) collected from the Persian Gulf coast. In this study, the antioxidant activity, iron chelating agent, DPPH and superoxide free radical inhibitory activity showed that alginates and fucoidan extracted from these algae showed high antioxidant activity. Anti-bacterial activity against seven pathogenic and non-pathogenic bacterial species showed that, Y. ruckeri was resistant to alginate and fucoidan. According to the results of this study, brown algae extract from S. boveanum can be used as anti-bacterial and anti-oxidant composition in food, pharmaceutical and cosmetic industries to increase the durability and prevent the oxidation of nutrients.
