Offer Description

All types of plant xylan are heteropolysaccharides comprising D-xylose-based backbone, which is decorated by a variety of substituents. The nature of the substituents, their frequency and distribution along the main chin is species-, tissue- and season-specific. The structure as well as enzymatic degradation of hardwood acetylglucuronoxylan and cereal arabinoxylan are well known. In contrast, the fine structure of heavily decorated corn fibre xylan including the presence of unique side chains still remains to be established . Similarly, its enzymatic degradation is only poorly resolved, that partially results from its resistance to the most common xylanases efficiently acting on glucuronoxylan and arabinoxylan. Although recently the xylanases depolymerizing the recalcitrant corn fibre xylan have been discovered, their mode of action and the eptopes recognized within the polysaccharide are still enigmatic. Moreover, du to the presence of unique side chains, their removal is expected to be catalyzed by novel enzymes awaiting their discovery. Looking up and characterization of the new enzymes participating in enzymatic breakdown of the recalcitrant corn fibre xylan will be the topics of the postgraduate study.
