Engineering precursor pools for increasing production of odd-chain fatty acids in Yarrowia lipolytica.

ABSTRACT: Microbial production of lipids is one of the promising alternatives to fossil resources with increasing environmental and energy concern. Odd-chain fatty acids (OCFA), a type of unusual lipids, are recently gaining a lot of interest as target compounds in microbial production due to their diverse applications in the medical, pharmaceutical, and chemical industries. In this study, we aimed to enhance the pool of precursors with three-carbon chain (propionyl-CoA) and five-carbon chain (β-ketovaleryl-CoA) for the production of OCFAs in Yarrowia lipolytica. We evaluated different propionate-activating enzymes and the overexpression of propionyl-CoA transferase gene from Ralstonia eutropha increased the accumulation of OCFAs by 3.8 times over control strain, indicating propionate
