Application
Cellulase, enzyme blend has been used for the purpose of enzymatic hydrolysis.[1]
Biochem/physiol Actions
Cellulase is responsible for the breakdown of insoluble plant polymer cellulosic substrates into soluble sugars, mostly cellobiose and glucose.[2][3] It specifically catalyzes the hydrolysis of β -1,4 glucosidic bonds in cellulose.[3] Animals do not naturally possess the ability to digest cellulose, but do so with the help of gut microorganisms.[4]
General description
Cellulase is a member of glycoside hydrolase family and is produced by a number of cellulolytic microbes.[2][3]
This product contains cellulases, ß-glucosidases, and hemicellulase, for the application of degrading cellulose to fermentable sugars. This product is effective on a wide variety of pre-treated lignocellulosic bimass materials, for converting the carbohydrates in these materials into simple sugars prior to fermentation, for application in biofuels research.

Ethanol organosolv (EOS) pretreatment is one of the most efficient methods for boosting biomass saccharification as it can achieve an efficient fractionation of three major constituents in lignocellulose. However, lignin repolymerization often occurs in acid EOS pretreatment, which impairs subsequent

Is this enzyme blend compatible with the feruloyl esterase enzyme ?
1 answer-
This product contains cellulases, beta-glucosidases, and hemicellulase for degrading cellulose to fermentable sugars. It is effective on a wide variety of pre-treated lignocellulosic biomass materials, converting carbohydrates into simple sugars prior to fermentation, applicable in biofuels research. The compatibility of this enzyme blend with feruloyl esterase (ferulic acid esterase; a hemicellulase) was not evaluated in-house. However, published literature indicates that ferulic acid esterase pretreatment facilitates the cellulase hydrolysis process by synergistically opening the crosslinked network structures of cell walls with other cellulases and hemicellulases. For example, see the articles by Zhao, M. et al., Carbohydrate Polymers, 313, 120885 (2023) and Xu, Z., et al., Front. Microbiol., Sec. Microbial Physiology and Metabolism, 11, 568716 (2020).

What is the recommended amount of Cellic CTec2 enzyme for saccharification of 1 gram cellulose?
1 answer-
Recommended enzyme trial dosages for Cellic CTec2 are 1.5%, 3.0%, 6.0%, and 30.0% weight/weight (grams enzyme per gram cellulose) for initial investigations. Further testing is necessary to refine the dose-response curve and assess the impact of time, solids loading, cellulose conversion, and enzyme dosage.

what is the concentration (units/ml) of the enzyme?
1 answer-
This Cellulase blend is a product of Novozymes. The analytical testing confirms that this material meets the 1000 unit/gram minimum activity, as well as the lot specific density. The density range is 1.0 - 1.3 g/mL. As an example, a 50 mL package size for a lot reporting a density of 1.2 g/mL with an activity of 1000 units per gram would have a minimum concentration of 1200 u/mL.
