| abstract |
The invention relates to a genetically engineered bacterium having an enzyme that converts acetyl-CoA to acetoacetyl-CoA, an enzyme that converts acetoacetyl-CoA to 3-hydroxybutyryl-CoA, and an enzyme that converts 3-hydroxybutyryl-CoA to 3-hydroxybutyrate. The bacterium may also have enzymes to produce other downstream products, such as 3-hydroxybutyryaldehyde, and 1,3-butanediol. Typically, the bacterium is capable of producing these products from a gaseous substrate, such as syngas or an industrial waste gas. |
