By leveraging data on elemental composition, gas transfer rates, and oxygen production rate, the method estimates biomass growth and assesses gas-liquid mass transfer coefficients. The approach uses indirect measurements to infer critical parameters, including biomass concentration, total inorganic carbon, and nitrogen levels. Results demonstrate accurate predictions of biomass growth and carbon dynamics, along with effective characterization of mass transfer coefficients. This method offers a robust tool for optimizing photobioreactor performance and enhancing process control.
