hydrolysis yieldsconcentrationcellulaseIn order to improve the hydrolysis of cellulose fiber and to obtain highly concentrated hydrolysate, two methods based on successive addition of enzyme and substrate were assessed. The first method, which required only substrate addition, allowed to increase by 50% ...
Hydrolysis of cellulose in an acidic medium yields d-glucose, yet human gastric enzymes cannot break the beta linkages between the glucose units (Beguin & Aubert, 1994; Lakhundi, Siddiqui, & Khan, 2015). Even more, cellulose requires structural and functional group modifications to overcome the ...
However, several steps necessary to achieve significant solubilization of biomass, notably harsh pretreatment conditions, impose economic barriers to commercialization. By employing hyperthermostable cellulase machinery, biomass deconstruction can be made more efficient, leading to milder pretreatment conditions ...

The synergistic effect of Ni and W. As mentioned above, the acid sites played an important role in the production of glycols, especially in the acidic hydrolysis of cellulose20,25. Therefore, we firstly investigated the syn- ergistic effects of Ni and W on the acid sites. As shown in...
Due to the fact that the present method of producing biofuel from lignocellulosic wastes involves enzymatic hydrolysis at a temperature of ≤ 50 °C, but it has many drawbacks including poor sugar yields, a sluggish rate of hydrolysis, and product inhibition throughout the process ...
In general, hydrolysis kinetics of cellulose (polysaccharides) and proteins (polypeptides) could be simply modeled by a single consecutive reaction following first-order kinetics. Rate constants of the hydrolytic conversion to the resulting monomers (glucose and amino acids) strongly depend on the type...
