Antioxidant and Antimicrobial Properties of Selected Red Seaweeds from Central Portugal

Throughout the ages, macroalgae have provided humankind with elements beneficial to human health, and often bioactive abilities. Yet, while today we fully acknowledge such potential, especially that of most widely known species, an even greater number species remain unaknowledged. This holds particularly true for highly diverse phylum Rhodophyta (red seaweeds) and, therefore, present study aims unveil antioxidant antimicrobial potential twelve red seaweed collected in central Portugal. Results obtained from assays ABTS TPC highlighted high scavenging capacity coralline algae Corallina officinalis, Ellisolandia elongata Amphiroa rigida, phenolic content Porphyra umbilicalis, whereas analyses through MIC determination emphasized activities Sphaerococcus coronopifolius Mesophyllum lichenoides against, respectively, Bacillus subtilis Saccharomyces cerevisiae. raised awareness waiting be discovered regarding less as rigida lichenoides. Therefore, believe this provides extra steps pinpointing encouraging further studies tailored toward a biotechnological perspective, ultimately, influencing current perspectives exploration seaweeds.
