  • 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%,...

  • Characterization of substrate-velocity relationships for the cellulase enzyme complex from Trichoderma viride

    Creator:
    Liaw, Ean-Tun
    Abstract:
    The influence of substrate and enzyme concentration on the rate of saccharification of two defined, insoluble, cellulose substrates, Avicel and Solka-Floc, by the cellulase enzyme system of Trichoderma viride has been evaluated. Assays utilized enzyme concentrations ranging from 0.014 to 0.056 filter paper unit per mL and substrate concentrations up...

  • 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...

  • Initial velocity analyses of milling effects on rates of enzyme-catalyzed saccharification of native wheat straw

    Creator:
    Nguyen, Quynh M.
    Abstract:
    There is considerable interest in developing environmentally friendly processes for the economical conversion of biomass plant material to biofuels, bioproducts and biomaterials. One approach to such a conversion process is to make use of enzymes for the conversion of plant polysaccharides to simple sugars; the simple sugars could then be...

  • 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...

  • 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...

  • Porosity, surface area and enzymatic saccharification of microcrystalline cellulose

    Creator:
    Tantasucharit, Usicha
    Abstract:
    The research described in this thesis was aimed at understanding how particle size, porosity, and enzyme accessible surface area influence the rate of saccharification of microcrystalline cellulose. Microcrystalline cellulose (MCC) is a commonly used substrate for the study of cellulolytic enzymes. MCC preparations of different particle size are commercially available....
