Excessive carbon dioxide (CO) emissions into the atmosphere have become a dire threat to the human race and environmental sustainability. The ultimate goal of net zero emissions requires combined efforts on CO sequestration (natural sinks, biomass fixation, engineered approaches) and reduction in CO emissions while delivering economic growth (CO valorization for a circular carbon bioeconomy, CCE). We discuss microalgae-based CO biosequestration, including flue gas cultivation, biotechnological approaches for enhanced CO biosequestration, technological innovations for microalgal cultivation, and CO valorization/biofuel productions. We highlight challenges to current practices and future perspectives with the goal of contributing to environmental sustainability, net zero emissions, and the CCE.
大气中过量的二氧化碳（CO）排放已成为人类和环境可持续性的严重威胁。实现净零排放的最终目标需要共同努力，包括 CO 封存（自然汇、生物质固定、工程方法）和减少 CO 排放，同时实现经济增长（CO 增值用于循环碳生物经济，CCE）。我们讨论了基于微藻的 CO 生物固存，包括烟道气培养、增强 CO 生物固存的生物技术方法、微藻培养的技术创新以及 CO 增值/生物燃料生产。我们强调了当前实践所面临的挑战和未来展望，以期为环境可持续性、净零排放和 CCE 做出贡献。
