Abstract:
A non-naturally occurring eukaryotic or prokaryotic organism includes one or more gene disruptions occurring in genes encoding enzymes imparting increased fumarate, malate or acrylate production in the organism when the gene disruption reduces an activity of the enzyme. The one or more gene disruptions confers increased production of acrylate onto the organism. Organisms that produce acrylate have an acrylate pathway that at least one exogenous nucleic acid encoding an acrylate pathway enzyme expressed in a sufficient amount to produce acrylate, the acrylate pathway comprising a decarboxylase. Methods of producing fumarate, malate or acrylate include culturing these organisms.
Abstract:
The invention provides a method of producing acrylic acid. The method includes contacting fumaric acid with a sufficient amount of ethylene in the presence of a cross-metathesis transformation catalyst to produce about two moles of acrylic acid per mole of fumaric acid. Also provided is an acrylate ester. The method includes contacting fumarate diester with a sufficient amount of ethylene in the presence of a cross-metathesis transformation catalyst to produce about two moles of acrylate ester per mole of fumarate diester. An integrated process for process for producing acrylic acid or acrylate ester is provided which couples bioproduction of fumaric acid with metathesis transformation. An acrylic acid and an acrylate ester production also is provided.
