Cellulose Hydrolysis. Most cellulase preparations contain various classes of cellulases and related activities. Hemicelluloses are a group of plant-derived heteropolysaccharides associated with cellulose and lignin. The most common hemicelluloses are xylan, glucuronoxylan, arabinoxylan, glucomannan and xyloglucan.

Title: Professor Affiliation: Department of Biotechnology, Norwegian University of Science and Technology In analysis package P121 we add an enzyme solution to a sample and incubate it for 3 days, monitoring the sugars that are hydrolysed over time. Subsamples of the hydrolysate are collected after 0, 12, 24, 48, and 72 hours of digestion and are analysed for monosaccharides (glucose, xylose, mannose, arabinose, galactose, rhamnose) and cellobiose using our ion chromatography system. Berghem and Pettersson (1973) reported on the T. reesei enzyme involved in the first step of cellolose degratation, a β-1,4-glucan cellobiohydrolase which acts upon crystalline cellulose.

However, cellulose-dissolving ILs have been found to severely inactivate the hydrolytic enzymes (cellulases) em- ployed in cellulose hydrolysis. This work

Enzymatic hydrolysis of cellulose is one of the bottlenecks in the commercialization of the process due to low hydrolysis rates and high cost of enzymes. A robust hydrolysis model that can predict cellulose is in a crystalline form with hydrogen bonding. Acid hydrolysis of hemicel-lulose occurs under less harsh conditions than cellulose because hemicellulose is an amorphous polymer (Quintero-Ramirez 2008).

It performs hydrolysis of cellulose during drying of beans. cellulases are widely used in textile industry, laundry detergents, pulp and paper industry for various

Cellulose and hemicellulose can be converted to ethanol, while lignin remains as a by-product: Hydrolysis Fermentation Hydrolysis Fermentation Cellulose Glucose Ethanol Hemicellulose Pentoses&Hexoses Ethanol → → → → In addition, there are some other hydrolysis methods in which no chemicals or enzymes are applied.

Bacterial cellulose has not been tested as a substrate for the C. stercorarium enzymes but turned out to be a better substrate for Cel48Y and Cel9I than Avicel, yielding more product and having a higher hydrolysis rate.

Investigations indicate, that the recovered glucose in turn can then serve as carbon source for on-site microbial production of those enzymes needed in deinking or in other pulp & paper processing steps. Both enzymes of C. thermocellum hydrolyse crystalline cellulose in a processive mode, as do Cs-Cel48Y and Cs-Cel9Z from C. stercorarium. Bacterial cellulose has not been tested as a substrate for the C. stercorarium enzymes but turned out to be a better substrate for Cel48Y and Cel9I than Avicel, yielding more product and having a higher hydrolysis rate.

In assessing chemical hydrolysis, we studied the effect of temperature, in addition to H₂SO₄ concentration and reaction time, on the Cellulase is a class of enzymes produced by the fungi bacteria and protozoans that generate cellulolysis. This process is actually the hydrolysis of cellulose. The enzymes are also produced by certain termites.
