Fresh water microalgae Chlorella sp. was isolated from water body of Taman Gelora, Kuantan, Pahang. The isolated monoculture was cultured in different concentration of POME (10%, 20%, 30%, 40% and 50%, v/v) as substrate. The maximal growth and biomass productivity found in 30% (v/v) of POME. The maximal dry biomass 1.56 g/L was obtained and extracted 39.1% lipid which approximate similar productivity as in conventional BG-11 medium 1.65 g/L of biomass and 41.5% lipid was obtained. Gas chromatography mass spectrometry analysis shown composition of fatty acid such as linolelaidic acid, oleic acid, palmitic acid, stearic acid, elaidic acid and α-linoleic acid as dominant. Highest fatty acid has found to be linolelsidic acid (41.69%). POME has potential to be used as a substrate for microalgae Chlorella sp. cultivation.
