Figure 6From: Effects of alkaline or liquid-ammonia treatment on crystalline cellulose: changes in crystalline structure and effects on enzymatic digestibilityEnzymatic hydrolysis of different cellulose samples. (a) Avicel PH 101, (b) α-cellulose, (c) cotton linters, (d) corn stover cellulose. (The error bars indicate the reproducibility (± 1 standard deviation) of digestions conducted in triplicate on the Avicel cellulose samples).Back to article page
