Study on high-CO2 tolerant Dunaliella salina and its mechanism via comparative transcriptomic analysis

we investigated the effect of inputs of CO2 at concentrations of between 1% and 30% on microalgal growth, CO2 fixation rates, and microalgal biomass chemistry using a Dunaliella salina strain under high salt conditions. Transcriptomic analysis was used to investigate the factors affecting microalgal tolerance for high CO2 concentration at a genetic level. These findings extend the knowledge which the key metabolic and biological pathways function in response to extremely high CO2 in marine microalgae.
