TL;DR: In this article, the authors achieved approximately 230 g L−1 of monomeric sugars after high solid enzymatic hydrolysis using deacetylation and mechanical refining (DMR) processed corn stover substrates produced at the 100 kg per day scale.

TL;DR: Deacetylation shows significant improvement on glucose and xylose yields during pretreatment and enzymatic hydrolysis, but it also reduces hydrolyzate toxicity during fermentation, thereby improving ethanol yields and titer.

TL;DR: Ru-Cu/HY showed the best HDO performance, affording the highest selectivity to hydrocarbon products, and all bifunctional catalysts proved to be superior over the combination catalysts of Ru/Al2 O3 and HY zeolite.

TL;DR: The possibility to scale up a mechanical refining technique to obtain similar enzymatic digestibility glucose yield enhancement as achieved by PFI milling and extrusion technologies is suggested.

TL;DR: This study effectively characterized a range of pretreatment reaction conditions using deacetylated corn stover at low acid loadings and identified an optimum reaction condition that was selected and used in a series of integrated pilot scale cellulosic ethanol production campaigns.
