Parameters describing alcoholic fermentation of corn straw—processing, with detoxification, T = 40 °C, simultaneous saccharification and fermentation (SSF) method.
| Parameters | Fermentation Time (h) | |||
|---|---|---|---|---|
| 0 | 24 | 48 | 72 | |
| Apparent extract (°Blg) | 5.00 ± 0.02 | 3.80 ± 0.00 | 2.90 ± 0.00 | 2.90 ± 0.00 |
| Concentration of ethanol (g/L) | - | 14.54 ± 0.38 | 16.98 ± 0.26 | 16.98 ± 0.00 |
| Actual extract (°Blg) | 5.00 ± 0.02 | 3.90 ± 0.10 | 3.20 ± 0.0 | 3.20 ± 0.00 |
| Reducing sugars in slop (mg/L) | 19.10 ± 0.03 | 6.12 ± 0.00 | 5.10 ± 0.00 | 4.90 ± 0.04 |
Notes: Table shows mean values and standard deviations. The results for 0 h of alcohol concentration were not subjected to the fermentation process. °Blg: degree Balling is the sugar content of 100 g an aqueous solution, comparable scales for indicating sucrose content is the degree Brix (°Bx).
