Cover Story: The production of odd-chain fatty acids (OCFA)-enriched lipids via fermentation using a genetically engineered Yarrowia lipolytica strain was investigated. The major fatty acid produced was the cis-9-heptadecenoic acid (C17:1). Its biosynthesis was optimized using a central composite design. The optimal responses maximizing cell density (optical density at 600 nm) and C17:1 content (%) in lipids were found using 52.4 g/L sucrose, 26.9 g/L glycerol, 10.4 g/L sodium acetate, 5 g/L sodium propionate, and 4 g/L yeast extract. Under these conditions, in a 5 L scale bioreactor, the respective contents of lipids and OCFA in culture medium were 2.52 ± 0.05 and 1.50 ± 0.05 g/L after 96 h fermentation. View this paper
