TLDR
The X-ray crystallography data indicate that the basic crystalline structure of the cellulosic component of corn stover is not altered by the ARP treatment, and low-liquid ARP can reduce the liquid throughput and residence time to 3.3 mL/g-biomass and 10-12 min, without adversely affecting the overall effectiveness.About:

Biobutanol production from fiber-enhanced DDGS pretreated with electrolyzed water
TL;DR: In this paper, a new pretreatment catalyst was employed to pretreat fiber-enriched DDGS, and three treatment times (10, 20, and 30 min) were examined in the pretreatment with a solid loading of 20% w/w.

Production of Bio-Ethanol by Integrating Microwave-Assisted Dilute Sulfuric Acid Pretreated Sugarcane Bagasse Slurry with Molasses.
TL;DR: The results showed that microwave-assisted dilute sulfuric acid pretreatment reduced the formation of toxic compounds compared to a pretreatment process involving “conventional heating”, suggesting that the production of bio-ethanol via integration of WPS with molasses is a superior method.

Ensiling biomass for biofuels production and multiple phase apparatus for hydrolyzation of ensiled biomass
TL;DR: In this paper, a method, apparatus and system for the hydrolyzation of ensiled biomass is described and a method for lower cost, improved efficiency alcohol production that uses the resulting liquid precursor hydrozate being produced at distributed sources is further disclosed.

Process for producing a sugar solution by combined chemical and enzymatic saccharification of polysaccharide enriched biomass
TL;DR: Concentrated sugar solutions obtained from polysaccharide enriched biomass by contacting biomass with water and at least one nucleophilic base is discussed in this article, where an enzyme consortium is contacted to produce a final saccharification product comprising fermentable sugars.

Methods and Systems for Saccharification of Biomass
Sarad Parekh,Carl P. Felice +1 more
TL;DR: In this article, methods and compositions for high yields while using reduced enzyme loads in saccharification and fermentation processes are presented. But, these methods increase the efficiency of enzymes and result in improved yields and composition of fermentation end products.

Fundamental factors affecting biomass enzymatic reactivity.
TL;DR: An empirical model was identified that describes the roles of lignin content, acetyl contents, and crystallinity indices in enzymatic hydrolysis and the digestibility of several lime-treated biomass samples agreed with the empirical model.

Pretreatment of corn stover by aqueous ammonia.
TL;DR: Corn stover was pretreated with aqueous ammonia in a flow-through column reactor, a process termed ammonia recycled percolation (ARP), and the enzymatic digestibility was related with the removal of lignin and hemicellulose, perhaps due to increased surface area and porosity.

The effect of initial pore volume and lignin content on the enzymatic hydrolysis of softwoods
TL;DR: In this paper, the lignin content and initial pore volume of Douglas fir pulps, a refiner mechanical pulp (RMP), sulphonated RMP, delignified RMP and a kraft pulp were compared on the basis of lignins content.

Evaluation of cellulase recycling strategies for the hydrolysis of lignocellulosic substrates.
TL;DR: Three recycling strategies were evaluated to determine their efficiencies over five successive rounds of hydrolysis and, in all three of the recycling strategies, lower cellulase activities were recovered from the substrates with higher lignin contents.
