Some microalgae can grow in mixotrophic condition with higher growth rate and lipid productivity compared with photoautotrophic condition. However, mixotrophic cultures are often not cost effective. In biodiesel production via transesterification, glycerol is produced along with fatty acid methyl ester. Using glycerol from transesterification for microalgae cultivation could be a way to reduce cultivation cost. In the present study, the effect of glycerol addition on the algal biomass and fatty acids productivity in Tetraselmis sp. MBEyh04Gc, was investigated. Addition of glycerol increased biomass and lipid productivity by 36% and 56%, respectively, compared with photoautotrophic cultures. The results suggest that glycerol can be used as a supplement in the culture of Tetraselmis sp., but further studies on the effects of quality and quantity of glycerol need to be conducted for optimization of mixotrophic cultivation. |
