Abstract
En 中文
• We assessed the biological and chemical carbon capture capacity of a novel strain of Scenedesmus obliquus (HTB1). • Microalgal calcium carbonate precipitation (MAICP) was induced at the conclusion of a robust growth experiment, producing 1.37 g/L of calcium carbonate. • A maximum dry biomass of over 6 g was achieved through growth with 10% CO2. • Our strain is highly productive under both elevated CO2 and high light (400 umol). • We demonstrate our strain as a strong candidate for point-source carbon capture from flue gas emissions.
