Air‐Mediated Biomimetic Synthesis of Polyhydroxyalkanoate with C4 Diol

) surpassing the values (<5.5) of previous approaches. The oligomer-containing products were reversibly converted to γ-BL and then to P4HB (28.9 kDa) via ring-opening polymerization, exceeding reported values (<16 kDa). This study provides the potential for large-scale synthesis of high-value PHAs from diverse non-grain-based diols, offering economic and environmental advantages.
