A biorefinery from Nannochloropsis sp. microalga – Extraction of oils and pigme...
Nobre, Beatriz P.; Villalobos, Fidel; Barragan, Blanca E; Oliveira, A. C.; Batista, Ana Paula; Marques, Paula Alexandra; Mendes, Rui L.; Sovová, H.The microalga Nannochloropsis sp. was used in this study, in a biorefinery context, as biomass feedstock for the production of fatty acids for biodiesel, biohydrogen and high added-value compounds. The microalgal biomass, which has a high lipid and pigment content (mainly carotenoids), was submitted to supercritical CO2 extraction. The temperature, pressure and solvent flow-rate were evaluated to check their ef...
Exploring Scenedesmus obliquus and nannochloropsis sp. potential as a sustianab...
Gouveia, L.; Batista, Ana Paula; Nobre, Beatriz P.; Marques, Paula Alexandra; Moura, Patrícia; Alves, Luís Manuel; Passarinho, Paual C.; Oliveira, A. C.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 fro...
