Microbial electrosynthesis from carbon dioxide feedstock linked to yeast growth for the production of high-value isoprenoids

•First demonstration of a two-stage bioprocess for terpenoids production from CO2.•It involves linking microbial electrosynthesis and yeast cultivation processes.•Higher yield and carbon conversion for Sclareol and yeast biomass than β-carotene.•Economic analysis suggested process feasibility for sclareol and yeast biomass.•Direct use of spent media containing acetate suitable for yeast biomass production.
