RT Journal Article T1 Microalgae, Seaweeds and Aquatic Bacteria, Archaea, and Yeasts: Sources of Carotenoids with Potential Antioxidant and Anti-Inflammatory Health-Promoting Actions in the Sustainability Era A1 Mapelli Brahm, Paula A1 Gómez Villegas, Patricia A1 León Vaz, Antonio A1 León Bañares, Rosa María A1 Meléndez Martínez, Antonio J. AB Carotenoids are a large group of health-promoting compounds used in many industrialsectors, such as foods, feeds, pharmaceuticals, cosmetics, nutraceuticals, and colorants. Consideringthe global population growth and environmental challenges, it is essential to find new sustainablesources of carotenoids beyond those obtained from agriculture. This review focuses on the potentialuse of marine archaea, bacteria, algae, and yeast as biological factories of carotenoids. A wide varietyof carotenoids, including novel ones, were identified in these organisms. The role of carotenoids inmarine organisms and their potential health-promoting actions have also been discussed. Marineorganisms have a great capacity to synthesize a wide variety of carotenoids, which can be obtained ina renewable manner without depleting natural resources. Thus, it is concluded that they represent akey sustainable source of carotenoids that could help Europe achieve its Green Deal and RecoveryPlan. Additionally, the lack of standards, clinical studies, and toxicity analysis reduces the use ofmarine organisms as sources of traditional and novel carotenoids. Therefore, further research on theprocessing of marine organisms, the biosynthetic pathways, extraction procedures, and examinationof their content is needed to increase carotenoid productivity, document their safety, and decreasecosts for their industrial implementation.
