Abstract
Microalgal lipid production is a promising long-term feedstock for the biofuels industry. In this study, photoautotrophic microalgal growth in open ponds has been investigated for the purpose of developing a kinetic model for the optimization and scale-up of the microalgae cultivation process. A comprehensive kinetic modelling approach for Chlamydomonas Reinhardtii growth in open pond has been developed to predict biomass growth and lipid accumulation under simultaneous influence of nitrogen, temperature and light intensity. The kinetic model is based on a multiplicative model approach that assumes equal contribution of the aforementioned limiting factors. The
developed model has been used in conjunction with in-house obtained experimental data to estimate model parameters and ultimately to enable the optimization of the microalgae cultivation in raceway open pond batch systems. Experiments were performed in 2 m3 open raceway ponds to define kinetic parameters of the scale-up level process manifested by nutrient and environmental parameters such as nitrogen, light and temperature. Scaled-up process simulations using such a comprehensive modelling framework will improve the competitiveness and sustainability of the microalgal biodiesel industry and will also enable the system industrial applicability and
commercialization.
