Engineering a semi-artificial photosynthetic biofilm for robust and high-efficiency CO 2 -to-methane conversion
Abstract
was decorated with silver nanoparticles. This modification rewires the electron transfer pathway, promoting a ferredoxin-independent mechanism and significantly enhancing cellular electron uptake. We achieved a state-of-the-art performance with a record 1.92% quantum yield and 97.1% methane selectivity by suppressing photodamage. This study pioneers the paradigm of integrating biofilms within hybrid systems. By elucidating its advantages and potential applications, our work provides a foundational blueprint for engineering the hybrid-biofilm microenvironment and designing practically viable reactors.
