Arabinoxylans (AXs) are major components of graminaceous plant cell walls, including those in the grain and straw of economically important cereals. Despite some recent advances in identifying the genes encoding biosynthetic enzymes for a number of other plant cell wall polysaccharides, the genes encoding enzymes of the final stages of AX synthesis have not been identified. We have therefore ad...

BACKGROUND Prebiotics are food ingredients, usually non-digestible oligosaccharides, that are selectively fermented by populations of beneficial gut bacteria. Endoxylanases, altering the naturally present cereal arabinoxylans, are commonly used in the bread industry to improve dough and bread characteristics. Recently, an in situ method has been developed to produce arabinoxylan-oligosaccharide...

• Arabinoxylans offer a new class of food ingredients through synergy with biorefining. The opportunity to produce AX arises from integration bioethanol production. fractions extracted sugarcane bagasse show potential as bread ingredient. Co-producing can enhance economics pinch analysis. integrated illustrates the required skills biorefinery engineer. (AX) are hemicellulose polysaccharides com...
