Technical Abstract: We have been investigating the production of value-added industrial products from vegetable oils and their component fatty acids through biocatalysis. One of such products is oxygenated fatty acid. A new microbial isolate, Pseudomonas aeruginosa PR3, converted oleic acid to 7,10-dihydroxy-8 (E)-octadecenoic acid and recinoleic acid to 7,10, 12-trihydroxy-8(E)-octadecinoleic acid. It also converted linoleic acid to isomeric 9,10,13 (9,12,13)-trihydroxy- 11E(10E)-octadecenoic acids. Another new microbial isolate, Clavibacter sp. ALA2, converted linoleic acid to 12,13, 17-trihydroxy-9(Z)-octadecenoic acid, a new anti plant pathogenic-fungus agent. Recently, we found that strain ALA2 also converted linoleic acid to four new compounds: 13,16-epoxy-7,12-dihydroxy-9(Z)-octadecenoic acid; 13, 16-epoxy-12-hydroxy-9(Z)-octadecenoic acid; 12,17;13, 17-diepoxy-9(Z)-octadecenoic acid and 7-hydroxy-12,17;13, 17-diepoxy-9(Z)-octadecenoic acid. Through biocatalysis, a large quantity of these bioactive polyhydroxy unsaturated fatty acids products can be obtained.
