| Abstract: | Hydrocarbon recovery was 32% and the total production of hydrocarbon in a two-phase extraction culture of Botryococcus braunii was 675 mg l–1, which was 19% higher than that of single-phase culture. Addition of 60 ml dihexyl ether at mid-growth phase gave the highest yield. Specific growth rate and recovery of hydrocarbon in this case were 0.022 h–1 and 26%, respectively. |
