Mathematical Modeling of Temperature Effect on Algal Growth for Biodiesel Application
Abstract Microalgae biomass is promising feedstock for the industrial production of biodiesel. Hence, research and development are needed in several domains especially optimizations of growth conditions including temperature effect for mass scale operation (biomass production, harvesting, lipid extraction, etc.). Since in Middle East region, seasonal temperature variation as well as more rapid daily fluctuations are liable to modify the growth conditions of microalgae in outdoor culture and hence affect production efficiency. Therefore, in this study, a mathematical model was developed to calculate how the algae sp. (Chlorella kessleri) will react at different temperatures. The model integrates Monod model and Arrhenius equation, and as such it describes the relationship of algal growth rate with culturing temperature and limiting nutrient concentration. The apparent activation energy and pre-exponential factors were calculated to be 2537 cal/mol and 0.0077 day−1, respectively. The developed models could be useful to visualize the effective impacts of temperature on outdoor algae culture.
