我们正在开发一种混合型生物电化学系统,用于实现二氧化碳的高效增值转化。该系统将外源电流直接导入蓝藻光合系统I以驱动二氧化碳固定过程,从而达成极高的能量转化效率。这种电驱光合作用能够生产出比人工光合作用产物结构更为复杂的碳氢燃料,同时强化碳代谢关键基因产物的合成。通过将外部电子或还原态单碳代谢物与光能相结合,该设计突破了天然光合作用的能量转化局限,为将二氧化碳转化为高价值有机化合物提供了稳定高效的路径。

[en]We are developing a hybrid bioelectrochemical system for the efficient valorization of CO₂. The system delivers an exogenous current directly to cyanobacterial Photosystem I to drive CO₂ fixation, achieving high energy-conversion efficiency. This electro-phototrophic process can produce hydrocarbon fuels that are structurally more complex than those obtainable by artificial photosynthesis, while also enhancing the production of key gene products involved in carbon metabolism. By combining external electrons or reduced one-carbon metabolites with light energy, the design overcomes the energy-conversion limitations of natural photosynthesis. This approach provides a stable and efficient route for converting CO₂ into valuable organic compounds.
