dc.descriptionThis work was supported by the Portuguese Foundation for Science and Technology (FCT) through the strategic project UIDP/04292/2020 and UIDB/04292/2020 granted to MARE – Marine and Environmental Sciences Center, and through CROSSATLANTIC project (PTDC/BIA-OUT/29250/2017), co-financed by COMPETE (POCI-01-0145-FEDER-029250). The Erasmus+ Program/KA1 AY 2017-18; Student Mobility for traineeship, has facilitated the collaboration of GDLF in the research activities of the present study at polytechnic of Leiria – Cetemares.pt_PT
dc.description.abstractBACKGROUD: In recent years, research on the bioactive properties of macroalgae has increased, due to the great interest in exploring new products that can contribute to improve human health and wellbeing. In the present study, the antioxidant and antimicrobial potential of six different brown algae of the Fucales order were evaluated, namely Ericaria selaginoides, Ericaria amentacea, Gongolaria baccata, Gongolaria usneoides, Cystoseira compressa and Sargassum vulgare (collected along the Mediterranean and Atlantic coasts). The antioxidant capacity was measured by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, the oxygen radical absorbent capacity (ORAC) and the ferric reducing antioxidant power (FRAP) and were related to the total phenolic content (TPC). The antimicrobial activity was evaluated measuring the growth inhibition of Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans. RESULTS: The highest antioxidant capacity was obtained for Ericaria selaginoides revealing the highest capacity to scavenge DPPH radical [half maximal effective concentration (EC50) = 27.02 ug mL−1], highest FRAP (1761.19 umol FeSO4 equivalents g−1 extract), high ORAC (138.92 umol TE g−1 extract), alongside to its high TPC (121.5 GAE g−1 extract). This species also reported the highest antimicrobial capacity against Staphylococcus aureus [half maximal inhibitory concentration (IC50) = 268 ug mL−1]. CONCLUSIONS: Among all studied seaweed, Ericaria selaginoides reveals the highest antioxidant and antimicrobial activities, and thus should be explored as a natural food additive and/or functional ingredient.pt_PT
