Comonomer compositional distribution, physical properties, and enzymatic degradability of bacterial poly(3-hydroxybutyrate-co-3-hydroxy-4-methylvalerate) copolyesters.

Abstract excerpt

Poly(3-hydroxybutyrate-co-3-hydroxy-4-methylvalerate) (P(3HB-co-3H4MV)) was synthesized by using Ralstonia eutropha strain PHB(-)4 (PHA-negative mutant) harboring with the N149S/D171G double mutation of PHA synthase gene from Aeromonas caviae (PhaC(Ac) NSDG mutant) with 4-methylvaleric acid and fructose as the carbon sources. Because the microbially synthesized P(3HB-co-3H4MV) samples were found to have broad...
