Interplay between CO₂ and light governs carbon partitioning in Chlamydomonas reinhardtii.

ABSTRACT: Increasing CO₂ availability is a common practice at the industrial level to trigger biomass productivity in microalgae cultures. Still, the consequences of high CO₂ availability in microalgal cells exposed to relatively high light require further investigation. Here, the photosynthetic, physiologic, and metabolic responses of the green microalga model Chlamydomonas reinhardtii were investigated in high or low CO₂ availability conditions: high CO₂ enabled higher biomass yields only if sufficient light energy was provided. Moreover, cells grown in high light and high CO₂ availability were characterized, compared to cells grown in high light and low CO₂, by a relative increase of the energy-dense triacylglycerols and decreased
