  1. a PHBV synthesized by different PHA synthases (PhaECHme, PhaEC1, or PhaEC3) in Har. hispanica; b Mw, weight-average molecular weight; Mn, number-average molecular weight; c Td, temperature at 5% weight loss determined by TGA; Tg, glass-transition temperature; Tc, cold crystallization temperature; Tm, melting temperature; ND, not detectable. The experiments were repeated three times and the results of one representative experiment were shown.
