  • Immobilized cellooligosaccharides in the study of trichoderma reesei cellobiohydrolases

    Creator:
    Sangseethong, Kunruedee
    Abstract:
    A novel type of model substrates, i.e. immobilized p-aminophenyl-β-D-cellooligosaccharides, was developed and used in the study of exocellulases. The two major cellobiohydrolases from Trichoderma reesei, CBH I and CBH II were used as representative enzymes. p-Aminophenyl derivatives of cellobiose (PAPG₂), cellotriose (PAPG₃), and cellotetraose (PAPG₄) were synthesized from the reaction...

  • Preparation and modification of cellooligosaccharides

    Creator:
    Akpinar, Ozlem
    Abstract:
    Cellooligosaccharides are the reaction intermediates produced during the hydrolysis of cellulose to glucose. Hence, they have the same chemical structure as cellulose, just shorter chain lengths. Cellooligosaccharides up to DP eight are soluble in water. The soluble cellooligosaccharides can be used "as is" in the food industry as non-digestible oligosaccharides...

  • Quantification and reactivity of cellulose reducing ends : implication for cellulose

    Creator:
    Kongruang, Sasithorn
    Abstract:
    The primary purpose of this study was to (1) develop methods for the analysis of and (2) provide information on the chemical nature of reducing ends in typical cellulose substrates used for the study of cellulolytic enzymes. The studies were designed such that values obtained for cellulose substrates were compared...

  • Utilization of lignocellulosic polysaccharides

    Creator:
    Fenske, John J.
    Abstract:
    Lignocellulosic biomass represents a vast supply of fermentable carbohydrates and functional aromatic compounds. Conversion of lignocellulosics to ethanol and other useful products would be of widespread economical and environmental benefit. Better understanding of the behavior of different lignicellulosic feedstocks in fermentation protocols as well as catalytic activities involved in lignocellulosic...
