Recombinant microorganism for producing poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

A recombinant microorganism transformed with a vector comprising an acetolactate synthase (αlsS)-encoding gene, an (R)-citramalate synthase (leuA)-encoding gene and an acetyl-CoA acetyltransferase (bktB)-encoding gene, wherein methylcitrate synthase-encoding genes prpC1 and prpC2 are deleted,

• wherein the alsS-encoding gene consists of the nucleotide sequence of SEQ ID NO:
• 1,
• wherein the leuA-encoding gene consists of the nucleotide sequence of SEQ ID NO:
• 2,
• wherein the BktB-encoding gene consists of the nucleotide sequence of SEQ ID NO:
• 3,
• wherein the prpC1 consists of the nucleotide sequence of SEQ ID NO:
• 6,
• wherein the prpC2 consists of the nucleotide sequence of SEQ ID NO:
• 7, and
• wherein the recombinant microorganism is recombinant Cupriavidus necator, and
• wherein the recombinant Cupriavidus necator produces a 3-hydroxyvalerate (3HV) in a poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) copolymer at 60 mol % or more when cultured in a medium comprising fructose.
