Description

Ec 3.2.1.8 is a highly purified enzyme preparation, specifically an endo-1,4-β-xylanase, identified by the CAS registry number 37278-89-0. This biocatalyst is critical for the efficient hydrolysis of xylan, a major hemicellulose component, into xylooligosaccharides and xylose. It is an essential processing aid for industries requiring the modification or breakdown of plant-based materials, offering a sustainable and specific alternative to harsh chemical treatments. Key sectors that utilize this enzyme include biofuel production, animal feed enhancement, food processing, and pulp and paper manufacturing.

Application

• Biofuel Production: Used to pretreat and hydrolyze lignocellulosic biomass (e.g., agricultural residues, wood chips) to release fermentable sugars for ethanol and biochemical production.
• Animal Feed Additive: Incorporated into poultry and swine feed to improve nutrient digestibility and feed conversion efficiency by breaking down non-starch polysaccharides in grains.
• Baking Industry: Acts as a dough conditioner and improves bread volume and crumb structure by modifying arabinoxylan in wheat flour.
• Pulp and Paper Bleaching: Facilitates elemental chlorine-free (ECF) and totally chlorine-free (TCF) bleaching processes by selectively removing xylan from pulp, reducing chemical usage.
• Food Processing: Employed in the clarification of juices and wines and the production of xylooligosaccharides (XOS) as prebiotic dietary fibers.
• Textile Processing: Used in the bioscouring of cotton fibers to remove impurities in an eco-friendly manner.
• Research & Development: Serves as a critical reagent in biochemical research for studying hemicellulose structure and enzymatic degradation pathways.

Quality Control

Our Ec 3.2.1.8 is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure activity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as enzymatic activity (XU/g or U/mg), protein content, pH optimum, temperature stability, and absence of specified microbial contaminants. Specifications can be aligned with food-grade (FCC) or feed-grade requirements as needed.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C for long-term stability. This product is hygroscopic (moisture-sensitive); ensure the container is kept sealed in a dry environment to prevent loss of activity. For extended storage under inert atmosphere, please contact us for specific recommendations.
