摘要

二氧化碳（CO2）生物合成是一种替代传统化学合成的前景广阔的方法。然而，其在工程中的应用却因气体传质率低而受到阻碍。加压是增强传质和提高合成产量的有效方法，但其基本机制仍不清楚。本综述探讨了高压对二氧化碳生物合成的影响，从微生物生理特性、气体传质和合成途径三个方面阐明了提高产量背后的机制。文章强调了加压在提高微生物活性和气体传输效率方面的关键作用，并特别关注如何将压力维持在微生物的耐受范围内，从而在不损害细胞结构完整性的前提下最大限度地提高产量。

Critical impact of pressure regulation on carbon dioxide biosynthesis

Carbon dioxide (CO₂) biosynthesis is a promising alternative to traditional chemical synthesis. However, its application in engineering is hampered by poor gas mass transfer rates. Pressurization is an effective method to enhance mass transfer and increase synthesis yield, although the underlying mechanisms remain unclear. This review examines the effects of high pressure on CO₂ biosynthesis, elucidating the mechanisms behind yield enhancement from three perspectives: microbial physiological traits, gas mass transfer and synthetic pathways. The critical role of pressurization in improving microbial activity and gas transfer efficiency is emphasized, with particular attention to maintaining pressure within microbial tolerance limits to maximize yield without compromising cell structure integrity.
