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

Figure 4

Effects of methanol volume on the biodiesel yield (■) and FAME content (▲) by in situ transesterification of C. pyrenoidosa. Reaction condition: 1 g algal powder with 6 mL n-hexane and 0.5 M sulfuric acid at 90°C. Methanol volume: 0.5, 1, 2, 3, 4, 6, 8, and 10 mL. Error bars = mean ± standard deviation.
