Wood-Ljungdahl microorganisms that produce polyhydroxybutyrate

A non-naturally occurring Wood-Ljungdahl microorganism capable of producing polyhydroxybutyrate comprising:

• a. a nucleic acid encoding a heterologous acetyl-CoA C-acetyltransferase (EC 2.3.1.9) enzyme that converts acetyl-CoA to acetoacetyl-CoA,
• b. a nucleic acid encoding a heterologous acetoacetyl-CoA reductase (EC 1.1.1.36) or a nucleic acid encoding a heterologous 3-hydroxybutyryl-CoA dehydrogenase (EC 1.1.1.157) enzyme that converts acetoacetyl-CoA to 3-hydroxybutyryl-CoA, and
• c. a nucleic acid encoding a heterologous polyhydroxyalkanoate synthase (EC 2.3.1.-) enzyme that converts 3-hydroxybutyryl-CoA to polyhydroxybutyrate.
