Docosahexaenoic acid (DHA) is a key omega-3 polyunsaturated fatty acid (PUFA) that is beneficial to human health. DHA is a major structural component of the gray matter of brain and eye retina and an important component of heart tissue. As a result, dietary DHA has been shown to play an important role in proper development of the brain and in eye of infants and in cardiovascular health. A number of algal groups, including diatoms, crysophytes, cryptophytes, dinoflagellates and others, have been reported to produce long chain PUFAs including DHA. DHA derived directly from microalgae grown in fermentation tank can avoid worries about oceanborne contaminants or toxins, which may be associated with fish-based DHA.Aurantiochytrium sp. is marine heterotrophic microalga containing DHA rich lipid. Heterotrophs can be an alternative to autotrophs which have problems with low maximum biomass densities. In this study, Aurantiochytrium sp. will be cultivated in a fermentation tank using a medium with glucose or other utilizable carbon source. DHA can be produced from microalgae by extracting lipid with high content of DHA. Total lipid with high content of DHA will be extracted from Aurantiochytrium sp. after applying cell disintegration techniques which include enzyme digestion, ultrasonication, osmotic shock and so on. The DHA content of microalgae will be determined by gas chromatography (GC) analysis of the total lipid extract. Residual microalgal biomass remained after lipid extraction will be reused as a biosorbent to remove heavy metals from aqueous solution. Heavy metals can be eliminated by making interactions with functional groups on residual biomass surface.
