Enhancing Enzymatic Hydrolysis of Cellulose by Ultrasonic Pretreatment
Slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). Susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. Maximum glucose yi...

متن کاملAccelerating enzymatic hydrolysis of chitin by microwave pretreatment.
Response surface analysis was used to determine optimum conditions [2% (w/v) chitin, 57.5 degrees C, 38 min] for microwave irradiation of chitin to improve its enzymatic hydrolysis. V(max)/K(m) of cabbage chitinase toward untreated and microwave-irradiated chitin was found to be 21.1 and 31.7 nmol h(-1) mg(-2) mL, respectively. Similar improvement was observed in the case of pectinase in its un...
متن کاملMicrowave Pretreatment of Switchgrass to Enhance Enzymatic Hydrolysis
Switchgrass is a promising lignocellulosic biomass for fuel-ethanol production. However, pretreatment of lignocellulosic materials is necessary to improve its susceptibility to enzymatic hydrolysis. The objectives of this study were to examine the feasibility of microwave pretreatment to enhance enzymatic hydrolysis of switchgrass and to determine the optimal pretreatment conditions. Switchgras...
متن کاملMitigation of cellulose recalcitrance to enzymatic hydrolysis by ionic liquid pretreatment.
Efficient hydrolysis of cellulose-to-glucose is critically important in producing fuels and chemicals from renewable feedstocks. Cellulose hydrolysis in aqueous media suffers from slow reaction rates because cellulose is a water-insoluble crystalline biopolymer. The high-crystallinity of cellulose fibrils renders the internal surface of cellulose inaccessible to the hydrolyzing enzymes (cellula...
