Perspectives of nervonic acid production by Yarrowia lipolytica.

Nervonic acid (cis-15-tetracosenoic acid, 24:1Δ15) is a long chain monounsaturated fatty acid, mainly exists in white matt er of the human brains. It plays an important role in the development of nervous system and curing neurological diseases. The limited natural sources and high price are considered limiting factors for the extensive application of nervonic acid. Yarrowia lipolytica is a high lipid producing yeast and engineered strain which can produce nervonic acid. The biosynthesis of nervonic acid has yet to be investigated, although the metabolism has been examined for couple of years. Normally, oleic acid is considered the origin of nervonic acid synthesis through fatty acid prolongation, where malonyl-CoA and acyl-CoA are initially concise by 3-ketoacyl-CoA synthase (KCS). To meet the high requirement of industrial production, the optimization of fermentation and bioreactors configurations are necessary tools to be carried out. This review article summarizes the research literature on advancements and recent trends about the production, synthesis and properties of nervonic acid.
