Abstract
The cultivation of microalgae was studied experimentally in a glass semi-continuous photo-bioreactor. The effect of temperature, light intensity and light frequency on the growth rate of Isochrysis galbana was investigated in the work. The results showed that the optimum temperature and light intensity for the higher growth rate were 25°C and 18000 lux, respectively, the biomass productivity was 1.20×10-3g/(L•h). When the light frequency was 20hz,the the growth rate of I.galbana was the highest, which was 18.6% higher than that in continuous illumination..
