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...

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...

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...

Salt and polyelectrolyte affect on food colloid function : polygalacturonic acid and egg albumen case studies

Creator:: Chen, Chi-Shen
Abstract:: The primary purpose of this study was to try to (1) provide information on the chemical nature, including turbidity formation, of polygalacturonic acid in different concentrations of NaCl solution. (2) use turbidity formation characteristics to develop an assay for determining the activities polygalacturonic acid depolymerases by using a polyelectrolyte. (3)...

Analytical approach to the quantitative analysis of silicon in plants : its application to plant silica extraction

Creator:: Boone, Carmen E.
Abstract:: The literature available on the silica content of herbaceous biomass, and its relative mobility in leaching/extraction systems, includes studies that have employed several different methods for silica quantification. This makes comparison of the data difficult. The objective of this thesis research was to determine the quantitative relationships between the measured...

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...

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...

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%,...

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...
