- Exploring Scenedesmus obliquus and nannochloropsis sp. potential as a sustianable raw material for biofuels amd high added value compoundsPublication . Gouveia, Luisa; Batista, Ana Paula; Nobre, B. P.; Marques, Paula; Moura, Patrícia; Alves, Luís; Passarinho, Paula; Oliveira, Ana Cristina; Villalobos, Fidel; Barragan, Blanca E; Palavra, António F.In this work, the authors propose a microalga-based integrated system, where optimization of several energy vectors (biodiesel, bioethanol and bioH2) is highlighted under the concept of biorefinery (Project PTDC/AAC-AMB/100354/2008). This involves the integration of different processes such as oil and sugar extraction from microalgae for biodiesel and bioethanol production respectively, and bioH2 production from the whole and/or biomass leftovers. The extraction of high value added compounds, such as carotenoids, contributes to the economic viability of the overall process.
