The greenhouse effect, which is believed to occur primarily as a result of the accumulation of carbon dioxide in the atmosphere, has become one of the major environmental concerns and received worldwide attention. In this paper, algae species screening and cultivation for efficient CO2 fixation are reviewed. The related dissolved inorganic carbon (DIC) utilization form and CO2 concentration mechanism (CCM) in the process of CO2 fixation by microalgae are analyzed. Four objectives of the highly effective photobioreactor design and operation are discussed, and the advances on CO2 mitigation technology with integration of microalgae (enzyme) and membrane bioreactor are also briefly introduced. In response to elevated CO2 concentration, much attention needs to be paid to the construction of transgenic microalgae with higher performance in CO2 fixation based on the further ascertainment of the related mechanism, and the development of effective CO2 biofixation system integrated with other kinds of advanced technology, such as membrane immobilization and separation.
温室效应被认为主要是由于大气中二氧化碳的积累而产生的，它已成为主要的环境问题之一，并受到全球关注。本文综述了用于高效固定二氧化碳的藻类物种筛选与培养。分析了微藻固定二氧化碳过程中相关的溶解无机碳（DIC）利用形式和二氧化碳浓缩机制（CCM）。讨论了高效光生物反应器设计与运行的四个目标，并简要介绍了微藻（酶）与膜生物反应器相结合的二氧化碳减排技术进展。针对二氧化碳浓度升高的情况，在进一步明确相关机制的基础上，需要高度重视构建具有更高二氧化碳固定性能的转基因微藻，以及开发与膜固定化和分离等其他先进技术相结合的有效二氧化碳生物固定系统。
