The scope of this study is to assess the main component of palm oil mill effluent (POME) to be used as organic carbon for microalgae. The applicable parameters such as optical density, chlorophyll content, mixed liquor suspended solid, mixed liquor volatile suspended solid, cell dry weight (CDW), carbon:total nitrogen ratio and growth rate were also investigated in this study. The characteristics and morphological features of the isolates showed similarity with Chlorella. Chlorella pyrenoidosa (CP) was found to be a dominant species in POME and Chlorella vulgaris (CV) could grow well in POME. Furthermore, the optimal lipid production was obtained at the ratio 95:05 CDW with highest lipid production by CP compared to CV. At day 20, CDW for CV species was obtained at 193 mg/L and with lipid content at 56 mg/L. Finally, the concentration ratio at 50:50 showed a higher absorbance of chlorophyll a for both strains.
