  • 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...

  • Quantitative polysaccharide analysis of lignocellulosic biomass

    Creator:
    Fenske, John J.
    Abstract:
    Lignocellulosic biomass is a potential source of fermentable sugars such as glucose. Enzymatic hydrolysis of cellulose is a viable method of solubilizing the glucose from biomass, but the cellulose fraction of native lignocellulosic material is shielded from enzymatic attack by the lignin-hemicellulose matrix surrounding it. Pretreating lignocellulosic biomass with dilute...

  • Nonstarch polysaccharide fractions of raw, processed and cooked carrots

    Creator:
    Kim, Sooyoun
    Abstract:
    The total and soluble nonstarch polysaccharide (NSP) components of raw, processed (canned and frozen) and home-cooked (boiled) Royal Chantenay carrots have been analyzed. NSP fractions were characterized by separation and summation of the monosaccharides resulting from acid hydrolysis of the parent polysaccharides. Total NSP was primarily composed of glucose, ~37%,...

  • Digesta passage rates in the rat

    Creator:
    Luick, Bret R.
    Abstract:
    The movements of digestion markers in the gut of the rat were investigated and the results of the investigation are reported in two manuscripts. The objective of the first study was to determine the influence of particle size of dietary wheat bran, chosen as a representative insoluble fiber, on the...

  • 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...

  • A filter paper assay for low cellulase activities and the cultivation of Trichoderma reesei on acid whey and sweet whey permeate

    Creator:
    Nordmark, Tor Soren
    Abstract:
    The traditional filter paper assay for saccharifying cellulase originally described by M. Mandels et al (1976) has been modified to make possible low activity determinations of Trichoderma cellulases. The enzymatic activity appears to decline during a prolonged incubation period if no precautions have been taken. By means of adding bovine...

  • Influence of extractives on the chemical analysis of switchgrass

    Creator:
    Tandjo, Djuhartini
    Abstract:
    This thesis summarizes an investigation into the need for removing extractives from herbaceous biomass feedstocks prior to their chemical characterization. Switchgrass (Panicum virgatum), was used in this study as a representative herbaceous biomass feedstock. The influence of extractives on the chemical analysis of switchgrass was done by comparing the composition...

  • 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...

  • Conversion of lignocellulosic biomass : analysis of substrate characteristics

    Creator:
    Meunier-Goddik, Lisbeth
    Abstract:
    The objective of this research was to investigate the influence of physicochemical properties of lignocellulosic biomass on the rate and extent of cellulose conversion, i.e. the "hydrolyzability" of the substrate. The initial two parts of this thesis investigated the interactions between various components of pretreated biomass. The relevance of cellulase...

  • The role of solvent extraction in the chemical characterization of corn stover feedstock

    Creator:
    Thammasouk, Khamphet
    Abstract:
    The consequences of extracting com stover feedstock with either 95% ethanol or hot water prior to the chemical analysis of the macrocomponents of that feedstock have been determined. Reports by others have recommended the removal of extraneous substance by solvent extraction prior to chemical analyses (Browning, 1967; TAPPI, 1988). The...
