Description

Cellobiohydrolase, Exo- is a key exo-acting glycoside hydrolase enzyme that specifically cleaves cellobiose units from the non-reducing ends of cellulose chains. This targeted action makes it a critical biocatalyst for the efficient and controlled depolymerization of crystalline cellulose, a major component of plant biomass. It is essential for industries focused on biofuel production, textile processing, and the development of advanced biorefineries where high-yield sugar conversion is paramount.

Application

• Biofuel Production: A core component in enzymatic cocktails for the saccharification of lignocellulosic biomass to produce fermentable sugars for bioethanol.
• Textile & Fiber Processing: Used in biostoning and biopolishing of cellulose-based fabrics like denim and cotton to achieve a soft finish and reduce pilling.
• Animal Feed Additive: Enhances feed digestibility and nutrient availability by breaking down fibrous cellulose in feedstocks.
• Pulp & Paper Industry: Applied in enzymatic refining and deinking processes to improve pulp quality and reduce energy consumption.
• Research & Development: Used as a model enzyme in biochemical studies of cellulase mechanisms and for developing optimized enzyme mixtures.
• Food Processing: Employed in the extraction and clarification of juices and in modifying food texture.
