Omega-3 and omega-6 LC-PUFA from photosynthetic microalgae: studies on Parietochloris incisa and Nannochloropsis sp Academic Article uri icon

abstract

  • Abstract Microalgae are primary natural producers of long-chain polyunsaturated fatty acids (LC-PUFA) with their widely recognized health-beneficial effects and various nutraceutical and pharmaceutical uses. The market for these products is continually growing, justifying efforts in the field of microalgal biotechnology to provide a sustainable alternative to diminishing marine fish oil resources. This chapter describes the occurrence of LC-PUFA in diverse microalgal classes and depicts the major pathways of LC-PUFA biosynthesis in microalgae. Effects of diverse environmental stressors on LC-PUFA accumulation are briefly considered. We will also summarize the results obtained in the authors' laboratories on arachidonic acid (20: 4 n-6) and eicosapentaenoic acid (20: 5 n-3) production by the green freshwater microalga Parietochloris incisa and the eustigmatophyte marine alga
