Figure 11From: Effects of pretreatment on morphology, chemical composition and enzymatic digestibility of eucalyptus bark: a potentially valuable source of fermentable sugars for biofuel production – part 1SEM images of eucalyptus bark samples treated with 2.0% of NaOH. (a) & (c): EG clone; (b) & (d): HGU clone. Globular structures assigned to lignin agglomerates are more frequently observed on EG than on HGU samples.Back to article page
