Technical Abstract: The bacterium Clavibacter ALA2 transformed linoleic acid into a variety of unsaturated hydroxy fatty acids. In our previous works seven novel fatty acids were identified: (1) 12,13,17- trihydroxy-9(Z)-octadecenoic acid (12,13,17-THOA); (2) 12-hydroxy-13,16-epoxy-9(Z)-octadecenoic acid; (3) 7, 12-dihydroxy-13, 16-epoxy9(Z)-octadecenoic acid; (4) 12,17; 13,17-diepoxy-9(Z)-octadecnoic acid (DEOA); (5) 7-hydroxy-12, 17;13,17-diepoxy-9(Z)-octadecenoic acid (7Hydroxy-DEOA); (6) 12,17:13,17-diepoxy-16-hydroxy-9(Z)-octadecenoic acid, and (7) 12,13-dihydroxy-9(Z)-octadecenoic acid (12,13-DOA). Recently, we found that strain ALA2 converted 12,13,17-THOA to DEOA and 7Hydroxy-DEOA. Therefore, 12,13,17-THOA is the intermediate for the production of diepoxy bicyclic fatty acid from linoleic acid. We also identified a new compound, 12,13,16-trihydroxy-9(Z)-octadecenoic acid (12,13,16-THOA) in the reaction mixture by GC/MS. The newly identified 12,13, 16-THOA is a possible precursor in the formation of tetrahydrofuranyl fatty acids.
