Microalgae are a species that is receiving much attention as the hope of future energy source. Microalgae possess the ability to photosynthesize, producing half of the atmospheric oxygen and using the greenhouse gas carbon dioxide. The advantages of microalgae as a source of biodiesel include its high oil content, no use of agricultural land or products and biodegradability. However, they are disadvantageous in biodiesel production in that species with high lipid content grow slowly. And species that grow rapidly will accumulate little lipid. Therefore, in order to develop a strain that is more suitable for biodiesel production, genetic engineering is a pivotal step. For genetic improvement of Chlamydomonas reinhardtii, relatively simple mutagenesis method using a chemical mutagen Ethyl Methanesulfonate was adopted in this study. From a large pool of mutants generated, superior mutants were screened out. Since high-lipid content is the most essential characteristic of an ideal microalgae strain for biodiesel production, lipid-rich strains were sought. Then, their characteristics as the potential strain for biodiesel were further analyzed using Nile-red staining, photoluminescence and gas chromatography.
