Algae Bioethanol and Biodiesel Production through Glycerol Fermentation
Researchers integrated the use of glycerol to produce ethanol in simultaneous production of biodiesel and bioethanol (Read More about Ethanol from Algae) production from algae. The process consists of growing of algae, determining the optimal fraction of oil vs. starch, followed by oil extraction, starch liquefaction and saccharification, to sugars, oil transesterification and the fermentation of sugars and glycerol. Common technologies can be adopted for the fermentation of sugars and glycerol.
The fermentation of glycerol doubles the bioethanol production. The energy and water consumptions are highly competitive to other process, wherein glycerol is sold out or converted to methanol.
