Investigation of some antibacterial and antioxidant properties of brown algae aqueous extract (Sargassum tenerrimum) collected from the Persian Gulf coast

these days, the importance of algae is growing as a major source of food, medicine and industry. The present study was conducted to determine the amount of anti-bacterial and antioxidant activity of the aqueous extract of S. tenerrimum on the Persian Gulf coast. In this study, measure some parameters like total antioxidant activity, total phenol, ability of iron ions trapping, DPPH free radical inhibitory activity and superoxide activity, showed that S. tenerrimum extract have high antioxidant properties (p<0/05). Also, the resistance of many pathogenic bacteria against artificial drugs and the side effects and cost of chemical drugs has attracted the scientist’s attention towards natural and herbal medicines. Therefore, antibacterial properties against seven different pathogenic and non-pathogenic bacteria were evaluated. Y. Ruckeri was the only bacteria resistant to this extract (p>0/05). According to the results of this study, the extract S. tenerrimum can be used as an antibacterial and antioxidant for food and medicine industry as well as cosmetics.
