Hemicellulase

Hemicellulase (CAS 9025-56-3) is an enzyme that breaks down hemicellulose, a structural polysaccharide in plant cell walls, into fermentable sugars and simpler oligosaccharides. Also marketed as Gammanase, Pentopan and Pulpzyme.

Where is Hemicellulase used?

• Baking: improves dough handling and crumb structure by degrading arabinoxylan networks in wheat flour
• Pulp and paper: biobleaching aid; enzymatic hemicellulose removal before chemical bleaching reduces chlorine consumption
• Textile and fiber processing: supports retting and fiber separation, reducing reliance on harsh chemical pre-treatments
• Biomass pre-treatment for second-generation bioethanol production, acting alongside cellulases to maximize sugar yield from lignocellulosic feedstocks

Good to know: Specific activity levels and pH optima vary by microbial source; buyers typically specify application conditions when sourcing.
