Beyond CO 2 : Incorporating Bicarbonate, Dynamic Carbon Speciation, and Stoichiometric Plasticity Into Algal Growth Models

Key Points

• The aim is to enhance algal growth models by integrating bicarbonate and carbon speciation factors.
• Analyzed experimental cultures using varying bicarbonate and carbon concentrations.
• Evaluated biomass and pH levels to derive estimates for algal growth models.
• Developed a framework for predicting carbon species dynamics during algal cultivation.
• Model predictions showed significant improvement in biomass estimates under carbon-limited conditions.
• Incorporating bicarbonate enhanced pH stability, facilitating better algal growth.
• Results indicate potential for improved carbon abatement and bioproduct formation in low-light environments.
