A novel lipids recovery strategy for biofuels generation on microalgae Chlorella cultivation with waste molasses
This study demonstrated a novel approach of lipids extraction with simultaneous biofuels conversion on microalgae Chlorella sorokiniana CY-1 cultivation using waste molasses as culture medium. The lipid extraction process was based on a hybrid liquid biphasic system (HLBS) which comprises of disrupt...
