Hydroxy fatty acids are important industrial materials. We isolated a microbial culture, Clavibacter sp. ALA2, which converts linoleic acid to many polyhydroxy fatty acids. Structures of the products were determined as: 12,13,17‐trihydroxy‐9(Z)‐octadecenoic (THOA, main product), 12‐[5‐ethyl‐2‐tetrahydrofuranyl]‐7,12‐dihydroxy‐9(Z)‐dodecenoic (ETDDA), and 12‐[5‐ethyl‐2‐tetrahydrofuranyl]‐12‐hydroxy‐9(Z)‐dodecenoic (ETHDA) acid. The yield of THOA was 25% and the relative amount of the products were THOA/ETDDA/ETHDA =9:1.3:1. The structures of the hydroxy unsaturated fatty acids resemble those of plant self‐defense substances.
