The objective of this study was to cultivate chlorella sp. in heterotrophic system using vermicompost tea culture media (made from vermicompost) to substitute the synthesis N8 media. The comparison (based on lipid production) were made between vermicompost tea, N8 media, N8 media with 0.45 g/L glucose, and N8 media with 0.45 g/L molasses under conditions: shaking at 200 rpm/min, at room temperature, for 15 days. It was found that the vermicompost tea gave highest cell concentrations, volumetric production rate of biomass and lipid were 2.80 g/L, 0.23 and 0.005 mg/L h respectively. While the cultivation of N8 media mixed glucose gave highest value it was found that the highest cell concentrations, volumetric production rate of biomass and lipid were 2.95 g/L, 0.35 and 0.01 mg/L h respectively.
