Abstract
Hydroxy fatty acids (HFAs), originally found in small amount mainly from plant systems, are well known to have special properties such as higher viscosity and reactivity compared with other normal fatty acids. Recently, various microbial strains were tested to produce HFAs from different unsaturated fatty acids. Among those microbial strains tested, Pseudomonas aeruginosa PR3 are well known to utilize various unsaturated fatty acids to produce mono-, di-, and tri-HFAs. Previously, we reported that strain PR3 could utilize triolein as a substrate for the production of 7,10-dihydroxy-8(E)-octadecenoic acid (DOD) via the induction of lipase activity (Chang et al., Appl Microbiol Biotechnol, 74:301-306, 2007). In this study, we focused on the development of the optimal environmental conditions for DOD production from triolein by PR3. Optimal initial medium pH and incubation temperature were pH 8.0 and 25°C, respectively. Magnesium ion was essentially required for DOD production. Optimal inoculum size, time for substrate addition, and substrate concentration were 1%, 12 to 24 h, and 300 mg, respectively.
