Abstract: Abstract: Arachidonic acid，Eicosapentaenoic acid and Docosahexaenoic acid are the essential polyunsaturated fatcyacigs of human and other animal. This paper reviews the influence of environmental impact factor (temperature, light radiation, chemical composition of culture solution, ventilation volume, methods of storage and culture, and so on) on the content of PUFAs in the marine microalgae, to provide a theoretical reference for the follow-up researcher. Producing the PUFA by the ocean microalgae has great advantage compared to extracting the PUFA directly from the fish. The core problem of microalgae industry is developping the efficient and cheap photo-bioreactor.
