Facilitated Channeling of Fixed Carbon and Energy into Chemicals in Artificial Phototrophic Communities

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 27, 2025

Light-driven CO2 biovalorization offers a promising route for coupling carbon mitigation with petrochemical replacement. Synthetic phototrophic communities that mimic lichens can reduce the metabolic burden improved utilization. However, inefficient channeling of and energy between species seriously hinders collaborative CO2-to-molecule route. Herein, we report universal sequestration (UCS) module based on photosynthetic microbes provides high-speed tunnel to heterotrophs. Compared traditional CO2-to-sucrose module, UCS sequestered 30% more into glycerol, generally available source high density. We demonstrated be highly compatible various industrial chassis genetically recalcitrant microbes, enabling rapid development synthetic without additional genetic manipulation. Notably, accelerated electron transport nutrient recycling systems may facilitate communications cooperative partners. These module-based efficiently channeled wide range chemicals, negative footprint -25.04 -440.74 kgCO2e/kg products. This strategy widens boundaries artificial boost carbon-negative biomanufacturing.

CO₂ Conversion to Butene via a Tandem Photovoltaic–Electrochemical/Photothermocatalytic Process: A Co-design Approach to Coupled Microenvironments

ACS Energy Letters, Journal Year: 2024, Volume and Issue: 9(9), P. 4369 - 4377

Published: Aug. 15, 2024

We developed a tandem, unassisted, solar-driven electrochemical and photothermocatalytic process for the single-pass conversion of CO2 to butene using only simulated solar irradiation as energetic input. The two-step involves reduction (CO2R) ethylene followed by dimerization butene. assessed two unassisted setups concentrate in CO2R reactor, achieving concentrations up 5.4 vol% with 1.8% average solar-to-ethylene 5.6% CO2-to-ethylene under 1-sun illumination. When effluent gas stream was passed through oligomerization we generated 600 ppm 3-sun Through analysis this process, identified that presence H2, CO, H2O leads rapid deactivation Ni-based catalyst.
