Abstract

Arachidonic acid (ARA, 5, 8, 11, 14-cis-eicosatetraenoic acid) is a relevant ω-6 polyunsaturated fatty acid, which plays essential roles in human immune, cardiovascular, and nervous systems. It is widely used in medicine, cosmetics, nutrition, and other fields. Traditionally, ARA is obtained from animal tissues. However, due to the limitation and unsustainability of existing resources, Microorganisms are a potential alternative resource for ARA production. In this regard, major efforts have been made on algae and filamentous fungi, among which Mortierella alpina is the most effective strain for industrial ARA production. In this review, we summarized the recent progress in enhancing M. alpina production by optimization of culture medium and fermentation process and genetic modification. In addition, we provided perspectives in synthetic biology methods and technologies to further increase ARA production.
