Electrochemical-biological hybrid conversion of captured carbon dioxide to bioproducts.

CO2 is a promising C1 feedstock for the sustainable production of fuels, chemicals, and materials, but its efficient conversion into value-added products remains challenging. Biological CO2 conversion provides high selectivity and access to structurally complex products under mild conditions, yet is limited by low prod...

Adaptive Laboratory Evolution (ALE) enables carbon-negative mixotrophic fermentation and enhanced chain elongation in Clostridium sp. JS66

Adaptive laboratory evolution enables carbon-negative mixotrophic fermentation and enhanced chain elongation in Clostridium sp. JS66.

Improving carbon recovery during sugar fermentation remains a major challenge because a substantial fraction of substrate carbon is lost as CO2 during central metabolism. To overcome this limitation, Clostridium sp. JS66 (JS66), an acetogen producing hexanoic acid from glucose, was subjected to adaptive laboratory evol...
