Oil extraction for biofuel production from edible oils such as palm oil, sunflower oil, canola oil, or soybean oil could be questionable since it affects directly the food supply. Microalgae oil has appeared as a new feedstock for the production of biodiesel as well as bioethanol, biosynthesis gas, or bio-oil through thermochemical and biochemical processes (Lopresto et al., 2017).

3 OIL EXTRACTION TECHNOLOGIES 3.1 Aqueous enzymatic extraction. Aqueous extraction is a traditional technique that uses water as a solvent to extract oil from oleaginous materials. Because water takes long to degrade the cell wall of oil‐bearing material, the process is less effective and results in low yield. To counter this limitation ...
