Comparative effects of biomass pre-treatments for direct and indirect transesterification to enhance microalgal lipid recovery

Frontiers in Energy Research, 2014
Microalgal lipid recovery for biodiesel production is currently considered suboptimal, but pre-treatment of algal biomass, the use of solvent mixtures and the positioning of transesterification can lead to increased yields.
