Partial enzymatic degradation of PHA fibers. SEM of drawn annealed P(3HB) fibers before (A) and after partial enzymatic degradation by R. pickettii T1 (B). (C) Intensity profiles of equatorial lines in X-ray fiber diagrams before and after partial enzymatic degradation by PHA depolymerase purified from R. pickettii T1 at 37 °C. The α and β indicate the reflections derived from α-form and β-form crystal, respectively [83]. Reproduced with permission from Iwata et al., Macromolecules; published by ACS, 2006.
