Hydrolysis of Cellulose and Hemicellulose
Cellulosic biomass includes agricultural (e.g., corn stover and sugarcane bagasse) and forestry (e.g., sawdust, thinnings, andmill wastes) residues, portions ofmunicipal solid waste (e.g., waste paper), and herbaceous (e.g., switchgrass) and woody (e.g., poplar trees) crops. Such materials are abundant and competitive in price with petroleum, and cellulosic biomass can provide a sustainable res...
متن کاملEnhancing 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 کاملMicrobial diversity of cellulose hydrolysis.
Enzymatic hydrolysis of cellulose by microorganisms is a key step in the global carbon cycle. Despite its abundance only a small percentage of microorganisms can degrade cellulose, probably because it is present in recalcitrant cell walls. There are at least five distinct mechanisms used by different microorganisms to degrade cellulose all of which involve cellulases. Cellulolytic organisms and...
متن کاملSynergistic interactions in cellulose hydrolysis
61 ISSN 1759-7269 10.4155/BFS.11.150 © 2012 Future Science Ltd In 1950 Reese et al. proposed a mechanism for cel lulose hydrolysis, which involved two general com ponents, C 1 and C x , acting in sequence [1]. According to the model, the C 1 component first disrupted and swelled the crystalline cellulose, possibly releasing soluble oligo saccharides into solution. The C x compo nent, which w...
متن کاملCellulose Hydrolysis: An Unsolved Problem
As on today, almost whole world is dependent on fossil fuels as a source of energy. With increase in world’s population there are growing concerns about diminishing fossil fuel resources, global warming and environmental pollution; hence there is a need for search of renewable resources to bridge the gap between the supply and demand of energy and chemicals. In this respect for production of bi...
