title: Biosynthesis of poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-3-hydroxyhexanoate) by metabolically engineered Escherichia coli strains.
abstract: The recombinant Escherichia coli strain, equipped with the newly cloned Aeromonas PHA biosynthesis genes, could produce a terpolymer of 3-hydroxybutyrate (3HB), 3-hydroxyvalerate (3HV), and 3-hydroxyhexanoate (3HHx) [P(3HB-co-3HV-co-3HHx)] from dodecanoic acid plus odd carbon number fatty acid. In addition, the orf1 gene of Aeromonas hydrophila was found to play a critical role in assimilating the 3HV monomer and in regulating the monomer fraction in the terpolymer.
