Chiral configuration analysis of PHA methyl esters and methyl (2S,3R)-3H2MV by GC–MS equipped with a chiral separation column. The GC–MS ion chromatograms (m/z 88) are shown. PHA copolymer samples of V35M2-J and V22M5 were biosynthesized by non-PhaJAc-expressing and PhaJAc-expressing strains, respectively. PHBM11 were biosynthesized in our previous study [18]
