Production of carotenoids and lipids by Dunaliella tertiolecta using CO2 from beer fermentation

- An integrated system of photobioreactor and yeast fermentation was studied.
- The CO2 profile affected the photobioreactor pH and the microalgae specific growth rate.
- The CO2-enriched cultures showed higher lipid and carotenoid content in the biomass.
- The integrated system was validated using CO2 from beer production.
