Abstract: Exhaustion of fossil fuels, negative effects of excess carbon dioxide in the atmosphere and high gas prices have all made it very crucial to find alternative and renewable sources of energy. Scientists are studying biological and physiological potential of microalgae as an alternative source for biofuel production. Microalgae have shown to be more economical among other crops including corn, sunflower and so on. They are also able to reduce industrial carbon dioxide by consuming it through the growth process and can be grown almost everywhere. Microalgae also have high growth rate which means higher production in a shorter time. They need less land compare to other crop for the same amount of lipid or oil. Among more than 100 species of microalgae, one with great lipid potential is Scenedesmus dimorphus. In this study we developed and evaluated five different permeabilization methods to determine the best lipid extraction method to produce more lipids from S. dimorphus biomass. The methods which were used in this research include wet-pellet, freeze-dry, sonication, grinding and freeze-thaw. Our results show that the most promising method is
