Molecular cloning Saccharomyces cerevisiae Hemicellulose Yeast fungi -- Genetics Dissertations -- Microbiology Thesis (M. Sc.) -- University of Stellenbosch, 1995. Cellulose, hemicellulose and lignin are the major polymeric constituents of plant cell walls, and form the major reservoir of fixed carbon in nature. Hemicellulose constitutes that fraction of plant cell walls that can be readily extracted by aqueous alkali, and is next to cellulose the most abundant renewable polysaccharide. Hemicelluloses are composed of both linear and branched heteropolymers of D-xylose, L-arabinose, D-mannose, D-glucose, D-galactose, and D-glucuronic acid. The majority of these heteropolymers are called xylans, of which D-xylose forms the polymer backbone. The heterogeneity of xylans requires the synergistic action of several hydrolytic enzymes to ensure complete microbial breakdown of xylan. The most prominent enzymes are endo-1,4-B-xylanases (xylanases) and B-xylosidases. The main substituents are liberated by a-L-arabinofuranosidases, acetyl (xylan) esterases, phenolic acid esterases, and a-glucuronidases. Xylanolytic enzymes are produced by a large variety of microorganisms: bacteria, fungi, as well as a few yeasts. Extensive research is devoted towards the exploitation of the hemicellulases for tge production of commodities of high value. These products may be found in food, feed, pulp and paper industries.
