Overview

Reports enhanced CO2 bio-fixation and biomass production in microalgae, highlighting implications for sustainability.

Key Points

  • The aim is to enhance CO2 bio-fixation and biomass production using an evolved strain of Chlorella vulgaris.
  • Adopted a biochemical approach to sequester CO2 and produce biomass.
  • Studied parameters such as inoculum size, photoperiod, light intensity, pH, and CO2 supply rate.
  • Evaluated batch and semi-continuous harvesting strategies for biomass yield.
  • Achieved maximum biomass production of 7.03 g/L and CO2 bio-fixation of 13.4 g/L in optimal batch conditions.
  • The adapted strain significantly outperformed the pre-adapted strain in biomass and CO2 bio-fixation.
  • Semi-continuous harvesting achieved biomass production up to 9.91 g/L with CO2 bio-fixation of 18.16 g/L.
