Verification of block-copolymerization property of PHAs synthesized by the engineered R. eutropha by solvent fractionation. 1H NMR (A) and 13C NMR (B) spectra of the PHAs extracted from IF017/pBPP-phaCAR, and 1H NMR spectra of the THF-insoluble fraction (C) and THF-soluble fraction (D). The methine proton regions in 1H NMR spectra and carbonyl carbon region in 13C NMR spectrum are shown
