Table S1.
Feeding strategy | Interval | Total elapse culture time, h | Effective glucan loading, g | Effective enzyme loading, mg protein⋅g glucan−1 |
All at once | 1 | 0–240 | 7 | 5 |
Two batches | 1 | 0–48 | 3.5 | 10 |
2 | 48–240 | 7 | 5 | |
Three batches | 1 | 0–24 | 2.33 | 15 |
2 | 24–72 | 4.66 | 7.5 | |
3 | 72–240 | 7 | 5 |
CELF-pretreated corn stover solids were added to flasks all at once, in two batches, or in three batches, resulting in different effective glucan and enzyme loadings during the first 3 d. Glucan and enzyme loadings were the same at the end of all fermentations at 7 g of glucan and 5 mg protein·g glucan−1, respectively.
