Effects of sonication at 150W and 300W power output on hydrolysis of wheat gluten using two proteinases (Protamex and papain) were evaluated in the present study. Sonication resulted in the increase in amounts of free sulphydryl (SH) of wheat gluten. Significant (P < 0.05) increase in SH contents at 300W power output was found compared with the control and those samples sonicated at 150W power output. Degree of hydrolysis (DH) and protein recovery (PR) of the wheat gluten hydrolysates increased with sonication time and power output. Significant (P < 0.05) increase in DH and PR of the wheat gluten hydrolysate from the sample sonicated by 300W power output was found compared to those sonicated by 150W output. Sonication caused the decrease in the relative percent of the large peptide fractions and increase in the relative percent of the small peptide fractions in the hydrolysates compared to the control. Structure change in insoluble wheat gluten proteins was the principal reason of improvement in their characteristics of enzymatic hydrolysis.

Background: Enzymatic hydrolysis of cellulose is an expensive approach due to the high cost of an enzyme involved in the process. The goal of the current study was to apply magnetic nanomaterials as a support for immobilization of enzyme, which helps in the repeated use of immobilized enzyme for hydrolysis to make the process cost-effective. In addition, it will also provide stability to enzyme and increase its catalytic activity. Objective: The main aim of the present study is to immobilize cellulase enzyme on Magnetic Nanoparticles (MNPs) in order to enable the enzyme to be re-used for clean sugar production from cellulose. Methods: MNPs were synthesized using chemical precipitation methods and characterized by different techniques. Further, cellulase enzyme was immobilized on MNPs and efficacy of free and immobilized cellulase for hydrolysis of cellulose was evaluated. Results: Enzymatic hydrolysis of cellulose by immobilized enzyme showed enhanced catalytic activity after 48 hours compared to free enzyme. In first cycle of hydrolysis, immobilized enzyme hydrolyzed the cellulose and produced 19.5 ± 0.15 gm/L of glucose after 48 hours. On the contrary, free enzyme produced only 13.7 ± 0.25 gm/L of glucose in 48 hours. Immobilized enzyme maintained its stability and produced 6.15 ± 0.15 and 3.03 ± 0.25 gm/L of glucose in second and third cycle, respectively after 48 hours. Conclusion: This study will be very useful for sugar production because of enzyme binding efficiency and admirable reusability of immobilized enzyme, which leads to the significant increase in production of sugar from cellulosic materials.
