Abstract
A method for producing a cis-9, trans-11 fatty acid from a fatty acid containing double bonds in the cis-configuration at positions 9 and 12, includes the step of combining a Lactobacillus microorganism with free fatty acids in a fermentation process. The conjugated fatty acid products can include, for example, cis-9, trans-11 conjugated linoleic acid (CLA).
Claims4
A method of producing cis-9, trans-11 fatty acids, the method comprising the step of:
- combining a fatty acid having a dissociated carboxyl group and unconjugated double bonds in the cis-9, cis-12 configuration with a Lactobacillus strain that can convert linoleic acid into conjugated linoleic acid, in a physiological buffer for a time sufficient to produce conjugated fatty acids wherein at least 50% of the conjugated fatty acids comprise conjugated double bonds in the cis-9, trans-11 configuration.
