Technical Abstract: Hydroxyl group of hydroxyl fatty acid (HFA) cause HFA to carry special properties such as higher viscosity and reactivity compared with other non-hydroxy fatty acids. Microbial conversion of oleic acid into 7,10-dihydroxy-8(E)-octadecenoic acid (DOD) caused DOD to carry strong antibacterial activity against several food pathogenic bacteria. However, industrial application of DOD as an antibacterial agent is limited by its high production cost. Hence we tried to use vegetable oil as a substrate for DOD production by Pseudomonas aeruginosa (PR3). Of those vegetable oils tested, we selected Korean pine seed oil as a substrate and studied about optimal culture conditions for DOD production.
