“…The values of the retrieved parameters µ max , K G , and K C agree with those reported by Erickson et al (1987) and are valid for low carbon concentrations. In addition, the inhibitory effect of large inorganic carbon concentration is successfully accounted for by the modified Monod model through the parameter K I .…”

Aims: The objective of this study is to develop kinetic models based on batch experiments describing the growth, CO 2 consumption, and H 2 production of Anabaena variabilis ATCC 29413-U T M as functions of irradiance and CO 2 concentration. Methods and Results:A parametric experimental study is performed for irradiances from 1120 to 16100 lux and for initial CO 2 mole fractions from 0.03 to 0.20 in argon at pH 7.0 ± 0.4 with nitrate in the medium. Kinetic models are successfully developed based on the Monod model and on a novel scaling analysis employing the CO 2 consumption half-time as the time scale.Conclusions: Monod models predict the growth, CO 2 consumption, and O 2 production within 30%. Moreover, the CO 2 consumption half-time is an appropriate time scale for analyzing all experimental data. In addition, the optimum initial CO 2 mole fraction is 0.05 for maximum growth and CO 2 consumption rates. Finally, the saturation irradiance is determined to be 5,170 lux for CO 2 consumption and growth whereas, the maximum H 2 production rate occurs around 10,000 lux. Significance and Impact:The study presents kinetic models predicting the growth, CO 2 consumption, and H 2 production of A.variabilis. The experimental and scaling analysis methods can be generalized to other microorganisms.

Mathematical model of the CO₂ solubilisation reaction rates developed for the study of photobioreactors

et al. 2013

View full text Add to dashboard Cite

The transfer of CO2 between the gas and liquid phases is one of the most important processes that occur during cultivation of microalgae in photobioreactors. A key factor that influences the rate of mass transfer is the concentration of CO2 in the liquid phase, which, in turn, depends on the rates of the reactions involved in CO2 solubilisation. This work presents a mathematical model for the rate of these solubilisation reactions with correlations that allow the calculation of the model parameters at temperatures from 5°C to 40°C. The model was validated using data of CO2 mass transfer from the literature obtained with two experimental systems: a bubble column for CO2 absorption and a flat‐panel photobioreactor. The model was further used to show that the increase in the rate of CO2 absorption that occurs at higher pH values is due to increased consumption of CO2(aq) in the solubilisation reactions and not to an increase in kLa. The pH decreases as CO2 is solubilised, therefore, when pH is controlled, the mass transfer rate is higher than it would be without pH control. Our model can be used as a tool to guide the operation, control and scale‐up of photobioreactors for the cultivation of microalgae.
