Abstract
Provided herein are methods of producing oils with reduced saturated fatty acids. The methods include culturing oil-producing microorganisms in a fermentation medium in the presence of one or more antifoaming agents under a controlled carbon consumption rate, wherein the culturing produces oils comprising fatty acids and wherein less than 35% of the fatty acids in the oil are saturated fatty acids.
Claims23
A method of producing a microbial oil comprising fatty acids, wherein the method comprises:
- culturing oil-producing Thraustochytrid microorganisms in a fermentation medium in the presence of one or more antifoaming agents continuously added to the fermentation medium under a controlled carbon consumption rate of between 1.5 and 4.5 g/L per hour, wherein the culturing produces an oil comprising:
- (a) saturated fatty acids, wherein 20% to 35% of the fatty acids are saturated fatty acids;
- (b) omega-7 fatty acids, wherein 10-30% of the fatty acids are omega-7 fatty acids comprising C16:1 (n-7) palmitoleic acid and C18:1 (n-7) cis-vaccenic acid, and
- (c) docosahexaenoic acid (DHA), wherein greater than 35% of the fatty acids are DHA.
