Valorization of Aquaculture Residues by Heterotrophic Cultivation of the Extremophilic Microalga Galdieria Sulphuraria for Protein- and Phycocyanin-Rich Biomass Production
This study evaluated a bioprocess using the thermo-acidophilic red microalga Galdieria sulphuraria to convert shrimp- and sludge-derived residues into biomass and pigments. Shrimp residues contained 57% (w/w) protein and 11% (w/w) lipids, whereas sludge contained 28–32% (w/w) protein and 13% (w/w) carbohydrates....
