Abstract:
To improve the enzymatic hydrolytic efficiency and reduce the supplementation of enzymes, the mixture designed experimental approach was used to optimize the composition of enzyme mixture and promote the hydrolysis of ball-milled corn stover. From the experimental results, a synergistic effect was found when combinations of the three enzymes, two kinds of cellulases and a kind of xylanase, were used. The optimal hydrolysis of pretreated corn stover accorded with enzymes activity ration of FPU/CMCase/β-glucosidase/xylanase = 4.4:1:75:829, and the hydrolysis efficiency of corn stover increased significantly compared with using individual enzyme. The results indicated that the mixture design experiment could be an effective tool for optimized enzyme mixture for lignocellulose hydrolysis.

Hydrolysis is a chemical reaction in which the addition of water breaks down a polymer into its simpler monomer units. For example, peptides break into amino acids, carbohydrates into simple sugars, and DNA into nucleotides. Enzymes often facilitate these processes.
Hydrolysis Reverses Dehydration Synthesis
Complex carbohydrates can be broken down by breaking the bonds between individual sugar units. The reaction breaks a glycosidic bond as water is added to the compound. The...
