Simulation Study on System Modeling of Spirulina and Chlorella in Light Algae Bioreactor

From the view of nutrient composition for astronaut,two kinds of microalgae are screened to mixed culture in LABR,and its mathematical simulation model is established by using MATLAB/Simulink software.The results show that,when the temperature is 30 ℃ and light intensity is 150μmol/(m2·s),chlorella and Spirulina can grow better in LABR,microalgae biomass is stable at about 1.1g/L.
