Abstract: Reduction of CO2 emissions has become a public concern due to the global warming. Based on the CO2 fixation in succinic acid fermentation process，the research progress is reviewed with the microorganism fixing CO2 and producing succinic acid simultaneously，the principle of succinic acid process，and the genetic engineering to optimize the process and improve the efficiency. This review also emphasizes that genetic reconstruction will play an important role in future investigation. Furthermore，concerning the importance of amplification effect in practical application，the effect of reaction conditions on other coupling fermentation process is increasingly important，and correlated researches should be strengthened in this field.

摘要： 随着全球温室效应问题日趋严峻，如何实现CO2的减排成为当今社会各界关注的焦点。本文以琥珀酸发酵过程中固定CO2为出发点，通过CO2固定产生琥珀酸的微生物及产琥珀酸的原理、CO2固定过程优化以及对CO2固定过程的基因改造等方面概述了琥珀酸发酵过程中固定CO2的研究进展。同时指出，基因工程改造将会成为以后研究的重心。考虑到实际应用过程中放大的重要性，在琥珀酸发酵过程中固定CO2的反应条件优化对于与其它发酵产CO2的过程的耦合也将显得日益重要，应加强这一方面的研究。
