Abstract Background Lignocellulose from fast growing hardwood species is a preferred source of polysaccharides for advanced biofuels and “green” chemicals. However, the extensive acetylation of hardwood xylan hinders lignocellulose saccharificati

Oat spelt arabinoxylan (OsAX) and spruce galactoglucomannan (GGM) are hemicelluloses that can be extracted in large quantities from side-streams of the agriculture and forest industries. They both form self-standing films, making them potential futur

Im Pflanzenreich kommt der Cellulose eine zentrale, strukturgebende Rolle zu. Daneben gibt es jedoch unzahlige Bestrebungen, dieses doch widerspenstige Polysaccharid abzubauen, vor allem im Zusammenhang mit der Gewinnung von Biokraftstoffen und erneu
