Engineering Escherichia coli for renewable benzyl alcohol production.

ABSTRACT: Benzyl alcohol is an aromatic hydrocarbon used as a solvent and an intermediate chemical in the pharmaceutical, cosmetics, and flavor/fragrance industries. The de novo biosynthesis of benzyl alcohol directly from renewable glucose was herein explored using a non-natural pathway engineered in Escherichia coli. Benzaldehyde was first produced from endogenous phenylpyruvate via three heterologous steps, including hydroxymandelate synthase (encoded by hmaS) from Amycolatopsis orientalis, followed by (S)-mandelate dehydrogenase (encoded by mdlB) and phenylglyoxylate decarboxylase (encoded by mdlC) from Pseudomonas putida ATCC 12633. The subsequent rapid and efficient reduction of benzaldehyde to benzyl alcohol occurred by the combined acti
