Rotating green to red: a biofilm-based approach to astaxanthin production
Microalgae are photosynthetic microorganisms able to convert light energy and inorganic nutrients into high-value compounds such as fatty acids, polysaccharides, or carotenoids. Astaxanthin, a red carotenoid pigment, is a very attractive molecule due to its antioxidant properties, which are significantly stronger than those of other carotenoids and vitamins. It has numerous applications in various industries,
