Progress in influence factors on morphology of Mortierella alpina producing arachidonic acid-rich oil
摘要
Abstract
Arachidonic acid,which is an essential polyunsaturated fatty acid in human nutrition, generally exists in the form of triglyceride. It has got more and more attention in food,medicine and other fields. At present,the main sources of arachidonic acid is from fermentation by the fungus of Mortierella alpina. The control of mycelia morphology plays a vital role in the whole fermentation process. In this review,the influence factors including nitrogen source,consumed carbon to nitrogen ratio,amino acid,mineral addition and dissolved oxygen on the fungus morphology were summarized. Some efficient morphology control strategies for arachidonic acid production by the fungus were presented. Future research should be focused on exploring the effect on morphology of M. alpina by many other factors,and establishing the relationship between morphology parameters and yield of arachidonic acid,which would guide the accurate control of morphology in industrial fermentation process.关键词
