Redirecting Carbon Flux Toward 2-Ketoglutarate Enables Photoautotrophic 1,4-Butanediol Production from CO2
Engineered cyanobacteria offer a sustainable platform for the conversion of light and CO2 into value-added chemicals. Unlike heterotrophic systems, cyanobacteria do not require organic carbon sources such as glycerol, glucose, or sucrose. In this study, we engineered Synechococcus elongatus PCC 7942 (hereafter 7942)...
