Abstract

The invention provides non-naturally occurring microbial organisms containing caprolactone pathways having at least one exogenous nucleic acid encoding a butadiene pathway enzyme expressed in a sufficient amount to produce caprolactone. The invention additionally provides methods of using such microbial organisms to produce caprolactone by culturing a non-naturally occurring microbial organism containing caprolactone pathways as described herein under conditions and for a sufficient period of time to produce caprolactone.
