文摘
- •
Saponifiable lipids (SLs) were extracted from wet biomass using ethanol and hexane.
- •
Intracellular R. oryzae lipase catalyzed the methanolysis of microalgal SLs.
- •
Biodiesel yield and lipase reuse were higher using SLs poorer in polar lipid.
- •
Biodiesel yield and lipase reutilization were higher in tert-butanol than in hexane.
- •
83% of microalgal SLs were transformed to biodiesel in the optimized conditions.
