Table 1.
The amount of lignocellulose components in corn straw, before and after chemical pretreatment (135 °C, 0.15 MPa, Ca(OH)2) and enzymatic hydrolysis (50 °C, pH 5.0–5.2, 4 h).
| Components of Lignoelluloses | Before Pretreatment | After Pretreatment | ||
|---|---|---|---|---|
| Result (%) | Uncertainty (%) | Result (%) | Uncertainty (%) | |
| Cellulose | 11.57 | ± 0.68 | 7.76 | ± 0.43 |
| Hemicellulose | 43.21 | ± 2.41 | 9.71 | ± 0.87 |
| Lignin | 2.22 | ± 0.04 | 1.26 | ± 0.03 |
| Other (Ash + Extractives) | 43.00 | ± 1.69 | 81.27 | ± 3.45 |
Notes: Table shows mean values and standard deviations. Extractives–non-structural material from biomass (the soluble matter in the residue).
