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...

Isolation of a natural antioxidant from shrimp waste

Creator:: Li, Shiao Jing
Abstract:: Shrimp waste samples were extracted with a variety of organic solvents. Each fraction was measured for antioxidant activity by determining the rate of oxidation of β-carotene-linoleic acid in an emulsion system. An ethanol extract exhibited the highest antioxidant activity. Purification of the most active fraction was accomplished by thin layer...

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...

Evaluating a value-added product through studies on consumer acceptability, sensory properties, and their correlations to biochemical and instrumental texture properties : the case of Pacific whiting (Merluccius productus) individually quick frozen (IQF) fillets

Creator:: Aksornsri, Weeraporn
Abstract:: Pacific whiting (Merluccius productus) is the most abundant groundfish species off the California, Oregon and Washington Coasts. The fish are mainly used as a raw material for the production of surimi. However, it is not economically wise to depend only on one product. There is a need to diversify the...

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...

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...

Concentration of anserine and carnosine in surimi wash water and their antioxidant activity

Creator:: Kaur, Jasvinder
Abstract:: Anserine and carnosine are water-soluble dipeptides that have antioxidant properties and are found in the skeletal muscle of mammals and fishes. These dipeptides are removed through the washing process in surimi production. The objective of this research was to determine the concentration of anserine and carnosine in surimi wash water...
