First, the morphology of PHB depolymerase adsorbed on a silicon wafer was characterized to show that one molecule of PHB depolymerase has dimensions of 2.2 ± 0.7 nm height and 16 ± 5 nm width. The observation of PHB depolymerase adsorbed on a P(3HB) single crystal indicated that the dimensions of enzyme on the crystalline surface in air were 1.2 ± 0.5 nm high and 28 ± 7 nm wide, while enzyme molecules with dimensions of 2.1 ± 0.6 nm height and 16 ± 7 nm width were detected in a buffer solution. Comparison of the dimensions of PHB depolymerase in air with those in a buffer solution showed that the enzyme was squashed in air, but not in a buffer solution. In addition, the influence of enzymatic adsorption on the molecular state of the P(3HB) crystalline surface was investigated. The AFM images of P(3HB) single crystals after enzymatic adsorption and washing with ethanol indicated that the adhesion of PHB depolymerase changed the molecular state and generated holes on the crystalline surface.</jats:p><jats:p><jats:boxed-text content-type=\"graphic\" position=\"anchor\"><jats:caption><jats:p>Illustration and AFM images of the adsorption process of PHB depolymerase on
