Sustainable energy conversion and
effective biosynthesis for value-added
chemicals have attracted considerable attention, but most biosynthesis
systems cannot work independently without external power. In this
work, a self-powered biohybrid system based on organic materials is
designed and constructed successfully by integrating electroactive
microorganisms with electrochemical devices. Among them, the hybrid
living materials based on S. oneidensis/poly[3-(3′-N,N,N-triethylamino-1′-propyloxy)-4-methyl-2,5-thiophene
chloride] (PMNT) biofilms for microbial fuel cells played a crucial
role in electrocatalytic biocurrent generation by using biowaste as
the only energy source. Without any external power supplies, the self-powered
biohybrid systems could generate, convert, and store electrical energy
for effective photosynthetic regulation and sustained chemical production.
This work provides a new strategy to combine comprehensive renewable
energy production with chemical manufacturing without an external
power source in the future.
