Natural dyes and pigments (vegetal, animal and microbial) are safer than synthetic dyes which have a polluting and harmful impact on the environment. Among natural microbial sources of pigments, microalgae are widely exploited for the production of phycobiliproteins, chlorophylls but especially carotenoids which have also health benefits. Production process of carotenoids from microalgae includes the steps of: biomass production and harvesting, extraction, saponification, separation and conservation. In this review the whole processes will be reviewed with special interest on different extraction steps and technics aiming to give a summarized overview of how carotenoids are produced from microalgae. Furthermore, improvements in cultivation and extraction systems, as well as carotenoid storage methods, are required for an economical, reproducible and ecofriendly large scale applications.
