In Situ Biodiesel Production from Fast-Growing and High Oil Content Chlorella pyrenoidosa in Rice Straw Hydrolysate

Figure 3

Effects of chloroform and n-hexane volume on the biodiesel yield and FAME content by in situ transesterification of C. pyrenoidosa. Reaction condition: 1 g algal powder with 4 mL methanol and 0.5 M sulfuric acid at 90°C. Solvent volume: 2, 4, 6, and 8 mL. Biodiesel yield (□) and FAME content (○) in the chloroform group, biodiesel yield (■) and FAME content (▲) in the n-hexane group. Error bars = mean ± standard deviation.
