Abstract：
Excessive carbon dioxide (CO2) 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 CO2 sequestration (natural sinks, biomass fixation, engineered approaches) and reduction in CO2 emissions while delivering economic growth (CO2 valorization for a circular carbon bioeconomy, CCE). We discuss microalgae-based CO2 biosequestration, including flue gas cultivation, biotechnological approaches for enhanced CO2 biosequestration, technological innovations for microalgal cultivation, and CO2 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.
摘要：
过量的二氧化碳（CO2）排放到大气中已经成为对人类和环境可持续性的严重威胁。净零排放的最终目标需要在二氧化碳封存(自然汇、生物量固定，工程方法)和减少二氧化碳排放，同时实现经济增长(循环碳生物经济的二氧化碳增值，CCE)。我们讨论了基于微藻的CO2生物固存，包括烟气培养，增强CO2生物固存的生物技术方法，微藻养殖技术创新，和二氧化碳增值/生物燃料生产。我们强调对当前实践和未来前景的挑战，以促进环境可持续性为目标，净零排放，以及CCE。
