AbstractThe bioconversions of oleic acid, linoleic acid, and ricinoleic acid by Pseudomonas aeruginosa PR3 were investigated. The conversion of oleic acid to 7,10‐dihydroxy‐8(E)‐octadecenoic acid (DOD) was improved to better than 80% yields by modifying the culture medium and reaction parameters. The microbial cultures were stable and retained the same level of DOD production capacity for up to 6 mon as examined herewith. Strain PR3 did not bioconvert linoleic acid. However, strain PR3 converted ricinoleic acid to a novel compound, 7,10,12‐trihydroxy‐8(E)‐octadecenoic acid (TOD), with a yield of about 35%. The product was further metabolized by strain PR3. TOD was purified by thin‐layer chromatography, and its structure was determined by 1H and 13C nuclear magnetic resonance and mass spectrometry. This is the first report on the production of 7,10,12‐trihydroxy unsaturated fatty acid by microbial transformation.

The present invention provides methods of making furfural fatty acids from (chloromethyl)furfural. The present invention also provides furfural fatty acids and nutritional supplements that include furfural fatty acids.
Disclosed is a method for preparing a furan fatty acid, more particularly a method for preparing a furan fatty acid by heat-treating 7,10-dihydroxy-8(E)-octadecenoic acid (DOD) in hexane. The present disclosure provides a simple method for producing 7,10-EODA from a dihydroxyl fatty acid precursor. Considering the difficulties in purifying natural furan fatty acids because of easy attack by peroxyl radicals and small quantity and the complicated multiple steps for chemical synthesis, the present disclosure provides a useful way to produce the biologically activity F-acid cost-effectively in large scale.

functionality and amphipathic property. The compound 7,10-dihydroxy-8(E)-octadecenoicacid (DOD) was generated fromoleicacid by Pseudomonas aeruginosa PR3 and was known to contain antimicrobial activities against a broad range of food-borne and plant pathogenic bacteria. Here, we attempted to convert DOD into its monoacylglycerol form using lipase for producing an amphipathic antibacterial agent. Consequently
