  • Wheat lignin as a functional dietary fiber component

    Creator:
    Junyusen, Tiraporn
    Abstract:
    This dissertation has focused on lignin byproducts that result from the alkali processing of wheat straw. The first study evaluated the application of “standard” lignin quantification methods for summative analyses of alkali-based processes. Mass closure during NaOH processing at 25, 50, and 75°C of wheat straw was evaluated using the...

  • 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...

  • Data Mining in Food Science Research and Technical Functionality of Wheat Straw-Derived Fibers

    Creator:
    Karaarslan Urhan, Tuba
    Abstract:
    This dissertation focused on data mining in food science research and on the technical functional properties of wheat straw-derived biorefinery-byproduct fiber preparations as related to potential applications as food ingredients. This first study evaluated the importance of electronic bibliographic database selection and multiple database usage during the information retrieval phase...

  • Composition and in vitro digestion of barley, oat, and wheat brans

    Creator:
    Gangloff, Mary Beth
    Abstract:
    In the field of nutrition, complex carbohydrates have become increasingly important in the last decade. The fiber fraction of foods has been implicated as modifying the etiology of several chronic diseases and the starch fraction is important with respect to the glycemic index of foods. This study has focused on...

  • Interactions of Trichoderma reesei exo-acting cellulases with p-aminophenyl 1-thio-β-D-cellobioside

    Creator:
    Piyachomkwan, Kuakoon
    Abstract:
    Cellulolytic enzymes capable of efficiently degrading crystalline cellulose are a complex mixture of endo- (endoglucanases) and exo-acting (cellobiohydrolases) enzymes. One approach to separating these enzymes is affinity chromatography. A new ligand, p-aminophenyl l-thio-β-D-cellobioside (APTC), is introduced for this purpose. The property of APTC in affinity chromatography is demonstrated using Trichoderma...

  • Saccharification and fermentation of lignocellulosic biomass using Trichoderma reesei cellulases and Saccharomyces cerevisiae

    Creator:
    Chung, Yun-Chin
    Abstract:
    The efficiency of cellulose hydrolysis under straight saccharification and simultaneous saccharification and fermentation (SSF) conditions was evaluated using three lignocellulosic materials (switchgrass, cornstover, and poplar), which had been pretreated with dilute sulfuric acid under conditions which optimized xylose concentrations in the prehydrolysate liquid. Yields of glucose, cellobiose and ethanol obtained...
