Antioxidant and Antibacterial Activity of Three Algae from Persian Gulf and Caspian Sea
The antibacterial and antioxidant activities of methanol and acetone extracts of three marine algae, including <em>Hypnea hamulosa</em>, <em>Gracilaria corticata</em> and <em>Enteromorpha intestinalis </em>wereinvestigated<em>.</em>Antioxidant activities were determined by means of total antioxidant capacity, total phenolic compounds, DPPH radical scavenging activity and ferric reducing antioxidant power. Antibacterial activity was determined using a paper disc diffusion method against pathogenic bacteria, including <em>Listeria monocytogenes</em>, <em>Escherichia coli</em> and <em>Bacillus subtilis</em>. Acetone extract of <em>E. intestinalis</em> showed the highest antioxidant activity and contained the highest phenolic compounds. The highest percentage of DPPH radical scavenging activity was observed in the methanol extract of <em>H. hamulosa </em>(p<0.05). The highest ferric reducing antioxidant power was observed in the methanol extract of <em>Glacilaria</em> (p<0.05). The strongest inhibition (p<0.05) against <em>L. monocytogenes</em> was shown by the methanol extract of <em>E. intestinalis </em>and the highest inhibition against <em>B. subtilis </em>and <em>E. coli</em> was observed in the acetone extract (p<0.05). In conclusion, <em>E. intestinalis</em> extracts showed favorable antioxidant and antibacterial activity suggesting its application in food and pharmacological industries.
