Description

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in cellulosic ethanol research. For more information see the article in biofiles and Enzymes for Alternative Energy Research.

Application

Hemicellulase from Aspergillus niger has been used in enzyme digestions.

Biochem/physiol Actions

Hemicellulase is a group of enzymes that catalyzes the breakdown of heteropolysaccharides. It includes glucanases that act on glucan. Similarly, xylanases and mannanases breakdown xylan and mannan respectively. Hemicellulase is prevalent among various bacteria, fungi and plants.

Analysis Note

An undefined mixture of glycolytic enzymes usually containing xylanase, mananase and other activities.

Other Notes

One unit will produce a relative fluidity change of 1 per 5 minutes using locust bean gum as substrate at pH 4.5 at 40 °C
