Investigating Lignocellulose in Cornstalk Pretreated with Trametes pubescens Cui 7571 to Improve Enzymatic Saccharification
This study investigated the degradation and enzymatic saccharification of cornstalk by white-rot and brown rot fungi. The fungal strains Trametes pubescens Cui 7571, Trametes velutina Dai 10149, and Antrodia wangii Cui 7568 were analyzed in solid-state fermentation cultures. Various extracellular enzyme activities were assessed to determine biochemical changes during the degradation process. Fo...
متن کاملOn energy consumption for size-reduction and yields from subsequent enzymatic saccharification of pretreated lodgepole pine.
This study investigated the effects of chemical pretreatment and disk-milling conditions on energy consumption for size-reduction and the efficiency of enzymatic cellulose saccharification of a softwood. Lodgepole pine wood chips produced from thinnings of a 100-year-old unmanaged forest were pretreated by hot-water, dilute-acid, and two SPORL processes (Sulfite Pretreatment to Overcome Recalci...
متن کاملMechanical deconstruction of lignocellulose cell walls and their enzymatic saccharification
Laboratory mechanical softwood pulps (MSP) and commercial bleached softwood kraft pulps (BSKP) were mechanically fibrillated by stone grinding with a SuperMassColloider . The extent of fibrillation was evaluated by SEM imaging, water retention value (WRV) and cellulase adsorption. Both lignin content and mechanical treatment significantly affected deconstruction and enzymatic saccharification o...
متن کاملSaccharification of lignocellulose
The increasing energy demand and the anticipated decline in crude oil production has led to an immense search for new energy sources. Plant cell walls contain lignocellulose that conserve great amounts of energy. These polysaccharides are of high importance for the search of renewable energy sources. Pretreatment of the cell wall is necessary in order to hydrolyse it to its component sugars. On...
متن کاملKinetic study of batch and fed-batch enzymatic saccharification of pretreated substrate and subsequent fermentation to ethanol
BACKGROUND Enzymatic hydrolysis, the rate limiting step in the process development for biofuel, is always hampered by its low sugar concentration. High solid enzymatic saccharification could solve this problem but has several other drawbacks such as low rate of reaction. In the present study we have attempted to enhance the concentration of sugars in enzymatic hydrolysate of delignified Prosopi...
