     Abstract Chlorella sp. KKU-S2 is a freshwater microalgae that can grow photoautotrophic, mixotrophic and heterotrophic cultivations. Heterotrophic and mixotrophic cultivations using organic carbon source offer several advantages over photoautotrophic cultivation such as good control of cultivation process, high biomass and cellular lipid content. Fed-batch cultivation offers advantages over batch cultivation including high biomass and productivity, elimination of substrate inhibition on cell growth. Therefore, the objective of this work is to cultivate Chlorella sp. KKU-S2 to enhance biomass and cellular lipid content of under fed-batch heterotrophic and mixotrophic cultivations using glucose as carbon substrate for their application as a sustainable feedstock for biodiesel production. Batch heterotrophic and mixotrophic cultivations were preliminary investigated using Bristol’s medium supplemented with 20g/L glucose, a biomass of 2.13 and 1.21 g/L were obtained with lipid content of 19.45 and 17.38% of cell dry weight (CDW) under heterotrophic and mixotrophic cultivation, respectively. Fed-batch fermentation was then performed and the obtained results presented that a biomass of 2.27 g/L with lipid of 0.771 g/L or lipid content of 33.93%CDW were obtained when the culture was performed under fed-batch heterotrophic cultivation. Whereas, a biomass of 3.82 g/L with lipid 1.295g/L or 33.9%CDW were found under fed-batch mixotrophic cultivation.
