Addressing the heavy reliance of conventional heterotrophic microalgal production on commercial glucose - whose supply chain embodies high carbon footprints - this study investigates cultivating the acidophilic microalga Galdieria sulphuraria using growth media prepared from starch via microwave-assisted hydrolysis. The work demonstrates an efficient, low-carbon approach for producing valuable biomass using short-chain sugars, paving the way for more sustainable biorefinery and green biotechnology applications. Galdieria sulphuraria offer value-added products including proteins as potential food products, phycocyanin (natural blue pigment), biomass for biofuels, etc. Read the full paper in Chemical Engineering Journal (Vol. 528, 172420).
