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 ...

It is known that dilute acid hydrolysis of cellulose at high temperature results in yields not exceeding 6065% of the potential glucose. All the models presented in the literature are based on the sequence: cellulose #x00BB; glucose #x00BB; degradation products. The underlying assumption of this...
In the first step, high glucose yields of above 80% could be obtained from the cellulose hydrolysis by a strong acidic cation exchange resin in 1-ethyl-3-methyl imidazolium chloride ([EMIM][Cl]) with gradual addition of water. In the second step, the resin was separated from the reaction...
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...

but it has many drawbacks including poor sugar yields, a sluggish rate of hydrolysis, and product inhibition throughout the process[137]. Fortunately, some novel cloned β-glucosidases fromThermotogaspp. have been known to be glucose resistant and toxic inhibitors that make them e...
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...
