Despite the widespread application of electrochemical systems in bioproduction, their detailed effects on photosynthetic organisms remain to be explored. In this study, a three-chamber electrochemical ion membrane system (EIMs) was optimized for minimizing carbon resource interference in the cathode chamber, thereby elucidating the role of EIMs in the light reactions of photosynthesis. By applying intermittent electrical stimulation, the photosynthetic activity of microalgae was enhanced, manifesting as the promoted accumulation of intracellular ATP and NADPH, while allowing the collection of hydrogen and oxygen as by-products. These findings suggest that EIMs not only facilitate photosynthesis by enhancing both light and dark reactions but also provide new avenues for improving the efficiency of photosynthetic production and advancing sustainable biotechnological processes.

电化学离子膜系统 （EIMs） 通过间歇性电刺激增强光合作用的光反应


尽管电化学系统在生物生产中得到了广泛的应用，但它们对光合生物的详细影响仍有待探索。在本研究中，优化了三室电化学离子膜系统 （EIMs），以最大限度地减少阴极室中的碳资源干扰，从而阐明了 EIMs 在光合作用光反应中的作用。通过应用间歇性电刺激，微藻的光合活性得到增强，表现为促进细胞内 ATP 和 NADPH 的积累，同时允许氢和氧作为副产物收集。这些发现表明，EIMs 不仅通过增强光和暗反应来促进光合作用，而且还为提高光合作用生产效率和推进可持续的生物技术过程提供了新的途径。
