Abstract
The present invention relates to a process for producing arachidonic acid. In one embodiment, Mortierella sect. schmuckeri microorganisms are cultured in fermentation medium, preferably containing a component of a complex nitrogen source. Further disclosed is a food product which includes Mortierella sect. schmuckeri microorganisms or lipid isolated from such microorganisms to enhance the arachidonic acid content of the food product.
Claims31
A method for producing arachidonic acid, comprising culturing microorganisms of the genus Mortierella sect. schmuckeri in a fermentation medium, wherein said Mortierella sect. schmuckeri is capable of producing at least about 0.7 grams of arachidonic acid per liter per day.
A method for producing a food product comprising the steps of:
- (a) culturing a microorganism of the genus Mortierella sect. schmuckeri, wherein said Mortierella sect. schmuckeri is capable of producing at least about 0.7 grams of arachidonic acid per liter per day;
- (b) recovering lipids comprising arachidonic acid from the culture medium;
- and
- (c) admixing said lipids with a food material.
A method to produce arachidonic acid, comprising culturing microorganisms of the genus Mortierella sect. schmuckeri in a medium comprising a source of assimilable organic carbon and a source of assimilable nitrogen, wherein at least about 21.9% of the total fatty acid produced by said Mortierella sect. schmuckeri is arachidonic acid.
