Table 1.

Partial and overall erosion rates along the a and b axes at the tip and root of the fibril-like crystals during enzymatic degradation [57]. Reproduced with permission from Numata et al., Biomacromolecules; published by ACS, 2005.

Sample	Partial erosion rates ^a, Nm/min			Overall erosion rates, mg/(min·cm²)
	Root	Tip
	a axis	a axis	b axis
^b H-P(3HB)	3.7	2.6	1.3	0.0007
M-P(3HB)	8.3	3.8	1.3	0.0015
L-P(3HB)	10.6	3.2	1.1	0.0018
P(3HB-co-6mol%-3HV)	12.4	6.8	2.0	0.0026
P(3HB-co-14mol%-3HV)	19.7	14.1	2.1	0.0065

^a Erosion rates were determined from real-time AFM observation as shown in Figure 6. ^b H-P(3HB), M-P(3HB) and L-P(3HB) mean high-molecular-weight (M_n:240,000), middle-molecular-weight (M_n:55,000) and low-molecular-weight P(3HB) (M_n:8,500), respectively.
