Method for producing 3-hydroxyadipic acid

A microorganism belonging to the genus Serratia producing 3-hydroxyadipic acid, wherein an enzymatic activity that catalyzes a reaction to produce 3-oxoadipyl-CoA and CoA from succinyl-CoA and acetyl-CoA is enhanced by introducing a gene encoding a protein having said enzymatic activity to said microorganism belonging to the genus Serratia, or by modifying a functional region(s) in a vicinity of a coding region in a gene encoding a protein having said enzymatic activity in said microorganism belonging to the genus Serratia.
