摘　　要：为更好地利用微藻实现碳捕获和生物质生产,研究微藻高CO2耐受/驯化的过程及其基本机制尤为必要.综述了微藻对高CO2耐受的生理现象、可能的耐受机制及分子响应机制的研究进展,分析了耐受高CO2微藻在生物减排、生物燃料开发等领域的应用前景,指出筛选耐受高CO2微藻并结合合理利用生理和基因工程手段以达到高效固碳的目标,是解决环境问题同时提高大规模微藻培养生产力的有效途径.This paper reviews the mechanisms governing high CO2 acclimation. Acclimation of the photosynthetic apparatus and robustness of pH homeostasis in the cell, rapid shutdown of CO2？concentrating mechanisms, and adjustment of membranes ’ fatty acid composition are currently believed to be the key mechanisms governing microalgae ’ s tolerance to high CO2 levels. The potential applications of high CO2 tolerate microalgae in biological, bio？fuel development and other fields are analyzed. Screening species with high CO2 tolerance and utilization of physiological and genetic engineering are effective ways to reduce CO2 emissions and increase microalgae productivity of large？scale cultivation.
