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...

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...

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...

Structural component composition of Pacific Northwest grass-derived biomass : A survey

Creator:

Masrungson, Duangdao

Abstract:

The structural component compositions of thirty nine non-commercial Pacific Northwest grasses were analyzed in order to develop a database of the grasses that may have application in bioconversion processes. The samples were chosen based on near infrared reflectance (NIR) data that suggested this group of grasses, collectively, was representative of...

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...

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)...

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...

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...
