Engineering Saccharomyces cerevisiae for high-level synthesis of fatty acids and derived products

Abstract

Fatty acids and fatty acid derivatives are important biorenewable products, as well as precursors for further transformation via chemical catalysis. This minireview focuses on recent advances in increasing the production of fatty acids and derived products in the yeast Saccharomyces cerevisiae. The engineering of upstream pathways to increase levels of the required precursors, fatty acid synthase systems to increase expression and to modify chain length, and downstream pathways to produce free fatty acids, fatty acid ethyl esters, fatty alcohols and alkanes are highlighted, and current challenges are discussed.
