Bicarbonate-Based Cultivation of Chlorella vulgaris: Growth Enhancement, Carbon Losses and Metabolic Trade-Offs

Carolina Maia, Mariana Cardoso, Joana Oliveira, Susana Casal et autres

Microalgae are photosynthetic microorganisms with high biotechnological potential, though optimising inorganic carbon supply remains a critical challenge to enhance growth, biomass quality, and carbon use efficiency. To address this, this study evaluated the impact of sodium bicarbonate supplementation (0, 0.5, 1.5, and …

Microalgae to Bioenergy: Optimization of Aurantiochytrium sp. Saccharification

Joana Oliveira, Sara Pardilhó, Joana Maia Dias, José C.M. Pires

Microalgae are a promising feedstock for bioethanol production, essentially due to their high growth rates and absence of lignin. Hydrolysis—where the monosaccharides are released for further fermentation—is considered a critical step, and its optimization is advised for each raw material. The present …
