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...

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...

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...

Apparent inhibition of Pacific whiting surimi-associated protease by whey protein concentrate

Creator:: Piyachomkwan, Kuakoon
Abstract:: Surimi is a seafood product which is used to manufacture restructured products such as artificial crab and lobster. Surimi is produced from fish fillets by washing to remove sarcoplasmic proteins and increase the concentration of myofibrillar proteins, and mixing with cryoprotectants. A valuable attribute of surimi is its ability to...

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...

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...

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....

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...
