- Diversity of bioactive compounds in microalgae: key classes and functional applicationsPublication . Osathanunkul, Maslin; Thanaporn, Suebsuya; Karapetsi, Lefkothea; Nteve, Georgia Maria; Pratsinakis, Emmanouil; Stefanidou, Eleni; Lagiotis, Giorgos; Avramidou, Eleni; Zorxzobokou, Lydia; Tsintzou, Georgia; Athanasiou, Artemis; Mpelai, Sofia; Constandinidis, Constantinos; Pantiora, Panagiota; Merino, Marián; Mullor, José Luis; Dobrovic, Luka; Cerasino, Leonardo; Ogawa, Tomohisa; Tsaousi, Meropi; Rodrigues, Alexandre M. C.; Cardoso, Helena; Pires, Rita; Rodrigues Figueiredo, Daniel; Figueiredo, Daniel; Costa, Inês F.; Anjos, Catarina; Labrou, Nikolaos E.; Madesis, PanagiotisMicroalgae offer a sustainable and versatile source of bioactive compounds. Their rapid growth, efficient CO2 utilization, and adaptability make them a promising alternative to traditional production methods. Key compounds, such as proteins, polyunsaturated fatty acids (PUFAs), polyphenols, phytosterols, pigments, and mycosporine-like amino acids (MAAs), hold significant commercial value and are widely utilized in food, nutraceuticals, cosmetics, and pharmaceuticals, driving innovation across multiple industries. Their antiviral and enzyme-producing capabilities further enhance industrial and medical applications. Additionally, microalgae-based biostimulants and plant elicitor peptides (PEPs) contribute to sustainable agriculture by enhancing plant growth and resilience to environmental stressors. The GRAS status of several species facilitates market integration, but challenges in scaling and cost reduction remain. Advances in biotechnology and metabolic engineering will optimize production, driving growth in the global microalgae industry. With increasing consumer demand for natural, eco-friendly products, microalgae will play a vital role in health, food security, and environmental sustainability.
- Microalgae as a selenium vehicle for nutrition: a reviewPublication . Pires, Rita; Costa, Margarida; Pereira, Hugo; Cardoso, Helena; Ferreira, Luís; Lapa, Nuno; Silva, Joana; Ventura, MárciaSelenium (Se) is essential for human and animal nutrition, playing a key role in antioxidant and immune functions. Organic Se is better for supplementation because it is more efficiently assimilated and less toxic than its inorganic form. Due to the scarcity of Se in European soils, supplementation in feed and food is necessary. Currently, inorganic Se (sodium selenite and selenate) and organic Se in Se-enriched yeast are approved by the European Food Safety Authority (EFSA) to address Se deficiency. However, Se-enriched microalgae present a promising alternative. By supplementing their growth media with Se, microalgae convert it into organic forms like Se-cysteine and Se-methionine, creating Se-enriched biomass. This biomass can serve as a valuable Se source with the additional benefits of microalgae. This review evaluates the viability of microalgae as a Se supplementation vehicle in food and feed and explores its commercial applications in the European Union (EU), along with emerging projects and innovations in the field.
