The fiber fractions were soaked in 15 wt%
aqueous ammonia at 1:10 solid-to-liquid ratio. The effects of
operating variables, including treatment times (6, 12, and
24 h), treatment temperatures (60 and 80 C), and cellulase
loadings (15 and 60 FPU/g-glucan) on the degree of enzymatic
hydrolysis were determined.
