A similar lipid extraction method using microwaves has already been reported for vegetable oils and animal fats (Mahesar et al., 2008 and Virot et al., 2008). Plus, this study found that, the microwave oven method was the most simple, easy, and efficient method for the tested microalgae. Furthermore, this lipid extraction method can be easily scaled-up. In conclusion, the microwave oven method was found to be the most applicable for large-scale lipid extraction from a microalgal biomass.
