Table 2 also includes the composition of pre-hydroysed jute
stick. The partial solubilization ofthe hemicellulose led to increased
contents of cellulose. The cellulose content increased to 43.9%
at 150 ◦C for 2 h pre-hydrolysis from 38.5% in the original raw
materials, which was further increased to 51.1% at 170 ◦C for 2 h
pre-hydrolysis. Yánez et al. (2009) showed that the glucan content
increased with temperature up to reach a maximum value
of 75.5 g/100 g oven dried pre-hydrolysis solids at 230 ◦C.
