Effects of alkaline or liquid-ammonia treatment on crystalline cellulose: changes in crystalline structure and effects on enzymatic digestibility

Table 5 The degree of polymerization and crystallinity of the initial cellulose samples used in this study

Cellulose samples	DP_n	DP_w	CI^a
Avicel PH 101	90	480	74
α-Cellulose	160	2000	57
Cotton linters	600	6600	73
Corn stover	170	3100	50

^aCI was measured by applying the amorphous subtraction method to the XRD of the celluloses. CI: crystallinity index; DP: degree of polymerization; XRD: X-ray diffraction.
