TL;DR: In this work, a mild and facile post-extraction using different reagents was evaluated to overcome recalcitrance for improving the enzymatic digestibility of acid-pretreated bamboo residues by removing the lignin and disrupting its inhibitory properties.

TL;DR: Response surface methodology (RSM) was applied to optimize culture conditions for the growth of Candida utilis with bamboo wastewater and a 1.7-fold enhancement of biomass of C. utilis was gained after optimization in shake-flask cultivation.

TL;DR: Improved enzymatic hydrolysis by adding 2-naphthol-7-sulfonate was ascribed to the higher negative surface charges, the lower enzyme non-productive binding, and the higher cellulose accessibility of pretreated substrates.

TL;DR: Although these inhibitors were present at concentrations much lower than their separately identified toxic levels, lactic acid fermentation with the hydrolysates showed much inferior performance compared to the control without inhibitor, suggesting synergistic or compounded effects of the lignocellulose-degraded compounds on inhibiting lactic Acid fermentation.

TL;DR: This work successfully demonstrated that recalcitrant waste woody biomass can be biorefined into both high-value XOS as well as relatively high yield of fermentable sugars.
