Combination of size reduction and mild alkali pretreatment may be a feasible way to produce bioethanol without rinsing and detoxifying the solid substrate. Based on that, a fermentation configuration named one-pot SSF in which pretreatment and fermentation steps were integrated was developed. Additionally, the effect of laccase on fermentation performance was investigated. Delignification was the major effect of the alkali pretreatment at 121°C for 60min. The highest glucose and xylose yield, which obtained from the smallest particle at a substrate loading of 2%, was 6.75 and 2.71g/L, respectively. Laccase improved the fermentation efficiency by 6.8% for one-pot SSF and 5.7% for SSF. Bioethanol from one-pot SSF with laccase supplementation reached 67.56% of the theoretical maximum, whereas that from SSF with laccase supplementation reached 57.27%. One-pot SSF might be a promising configuration to produce bioethanol because of 100% solid recovery, and rinsing water and detoxification elimination.
