Marine macroalgae - applications in the industrial sector and therapeutic potential

Ana Marta Goncalves

At the last decade increased the interest and search for new natural compounds from marine biodiversity to discover novel bioactive substances. It is expected that many naturally bioactive marine compounds with novel structures and bioactivities may be found among marine metabolites. Moreover, there is also an urgent need for bioactive compounds environmentally friendly or with â??greenâ? chemical properties. Still, there is a long way from discover to the applications of this new natural compounds, because they need to be cost efficient and be economically viable from an ecological point of view. Marine macroalgae produce significant amounts of primary and secondary metabolites that present a wide variety of bioactive properties, including antioxidant, antiviral, antimicrobial, antitumoral, anti-inflammatory, anti-aging or immunomodulatory potential, with also antibiotic properties. These molecules are promising candidates for many possible applications such as in pharmaceutical, nutraceutical, cosmetic and medicine areas but also in agriculture or feeding. These applications may promote several benefits to humansâ?? daily life, and so to a better quality of life. Still, some substances may be poisonous to humans and to other organisms, or become toxic upper to a certain quantity. In this topic will be focused the marine macroalgae benefits, applications in industrial sector and therapeutic potential.
