Abstract:
In the current energy context, maximising the production of energy from renewable sources is crucial. The potential of some microalgae to generate biofuels such as biodiesel from their fat content is quite relevant. In addition, by using cell disruption techniques to break down intercellular membranes, it is possible to increase the fat content after an extraction process. A higher amount of available lipids will lead to a higher biodiesel production after a transesterification process. In this work, a comparison of different cell disruption techniques applied to two different extraction procedures is carried out; in Soxhlet and cold extraction, the microwave pretreated cells allowed obtaining a percentage of total fat content above 90%, while in cold extraction. Whereas cold extraction led to higher percentages of lipids if pulsed electric field has been applied.
