The authors show that the integration of CO₂ Electrolysis with microbial fermentation can efficiently produce value-added multicarbon products such as poly-3-hydroxybutyrate (PHB) from CO gas₂This biohybrid system involves electrochemical conversion of CO₂ for the formation and subsequent biological conversion of formate to PHB using Cupriavidus necator.
