“…In recent years, considerable effort has been devoted to overcoming this limitation . One approach, the emerging cell surface engineering technology, has been utilized to encapsulate cells with nanomaterials to enhance the efficiency of hydrogen production. − For example, Tang et al found that silicification-induced green algae aggregates achieve sustainable photobiological hydrogen production under natural aerobic conditions . Huang et al strategically utilized encapsulation of cells in an oxygen-consuming shell comprised of polydopamine, laccase, and tannic acid to enhance their hydrogen production efficiency .…”

External electric field has the potential to influence metabolic processes such as biological hydrogen production in microorganisms. Based on this concept, we designed and constructed an electroactive hybrid system for microbial biohydrogen production under an electric field comprised of polydopamine (PDA)-modified Escherichia coli (E. coli) and Ni foam (NF). In this system, electrons generated from NF directly migrate into E. coli cells to promote highly efficient biocatalytic hydrogen production. Compared to that generated in the absence of electric field stimulation, biohydrogen production by the PDA-modified E. coli-based system is significantly enhanced. This investigation has demonstrated the mechanism for electron transfer in a biohybrid system and gives insight into precise basis for the enhancement of hydrogen production by using the multifield coupling technology.
