Abstract (sommario):

Self-immobilisation enzyme technologies, such as SphereZyme™, suffer from the lack of applicability to hydrolyse large substrates. Solid support immobilisation is usually a method of choice, to produce a stable biocatalyst for large substrates hydrolysis in the industry. In order to investigate this limitation, a commercial protease called Alcalase® was chosen as a model enzyme due to its natural activity (hydrolysis of large substrates-proteins). Prior to immobilising through the SphereZyme™ technology, Alcalase® was partially purified through dialysis followed by CM Sepharose™ FF cation exch

Thesis (PhD (Process Engineering))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: There is growing interest to utilise xylan as speciality biopolymers in similar ways as high molecular weight polysaccharides such as starch and cellulose. The need to utilise xylan as alternative to cellulose and starch has increased because the cellulose and starch have many other competing uses. Unlike cellulose and starch, xylans are heteropolymers with higher degree of substitution and are of lower molecular mass and therefore, do not readily become insoluble to form hydrogels and biofilms.

Abstract (sommario):

This work studied the improvement of stability, physical properties and enzymatic inactivation in fruit beverages by applying the ultrasound technology (US). In the first part, the effect of the US application on peach juice processing was evaluated. The macroscopic changes on pulp sedimentation stability, turbidity, colour and rheological properties were evaluated. As a result, it was demonstrated that the improvement in each of the properties evidenced at the macroscopic level involves interaction of complex mechanisms which depend directly on changes at the microscopic level, such as the st

Abstract (sommario):

Enzymes are promising stimuli for the development of responsive biomaterials for biomedical applications. Enzymes are inherently present in the biological environment thus cleverly designed materials for biomedical applications may require no external stimuli to ellicit the required material response. They have been targeted as stimuli in self assembly of bulk materials owing to the material changes in chemical composition afforded by the enzyme interaction. The first examples of autonomous self-regulated drug delivery systems have been reported via the development of reversible enzyme respons

Aberrant expression of short non-coding micro RNAs (miRNA) in many human diseases, along with remarkable stability in physiological media, has made them attractive clinical biomarkers. In particular, miRNA-122 is substantially elevated in plasma of patients with established drug-induced liver injury and can also be used to identify early liver injury when current markers, such as alanine aminotransferase (ALT), still show normal levels. The development of a rapid test for miRNA-122 e.g. in drug poisoning would allow earlier and more sensitive clinical diagnosis of liver injury. Nucleic acids a

Abstract (sommario):

Finding alternatives to petroleum-based energy sources is of interest since it could reduce the emissions of net carbon dioxide to the atmosphere by increasing the usage of renewable energy sources. To do so improvements are needed in the renewable energy production sector. Biogas production is of interest since the anaerobic digestion process can degrade many different biomolecules and is, contrary to e.g. bioethanol and biodiesel, not dependent on specific molecules. Thus, many wastes such as slaughterhouse waste, sludge from waste water treatment and lignocellulose residual material etc. ca

Background: Insulin is an important hormone for glucose homeostasis. It is released from β-cells in the endocrine pancreas as a response to increased concentrations of plasma glucose. The major effect of insulin is the facilitation of cellular uptake and storage of glucose as glycogen. Insulinomas are tumours that produce excessive amounts of insulin resulting in hypoglycaemia. The condition has been observed in dogs and cats and is often malignant. One part of establishing the diagnosis is confirmation of elevated concentrations of insulin in a hypoglycaemic sample.

Abstract (sommario):

Diabetes has, in the past three decades, surged immensely. Because of this, new insulin analogues are constantly in the making. In clinical studies, the presence of antidrug antibodies can prove a challenge when measuring insulin. In order to overcome the interference from antidrug antibody complexes on the total insulin measurement in human serum, several pre-treatment methods on insulin and polyclonal antibodies spiked samples were tried using ELISA analysis. Several different methods were tried, acid dissociation using a glycine buffer with and without ethanol in different concentrations,

Abstract (sommario):

Lignin is the only plant biomass that contains aromatic groups in its structure and can provide a wide range of low molecular weight aromatic chemicals if its depolymerisation can be achieved successfully. Currently, lignin is mainly produced as a waste by-product by the paper and pulp industry and biorefineries. Therefore, the transformation of the phenolic-rich lignin into value added aromatic platform chemicals can be regarded of primary concern to improve the economic profitability of biorefining. Moreover, being a renewable resource, the consumption of fossil fuels will be reduced if lign

Abstract (sommario):

L'objectif de ce travail a été d'étudier l'immobilisation d'enzymes sur des matériaux membranaires en utilisant la technique de dépôt multicouches de polyélectrolytes. Pour cela, nous avons utilisé deux enzymes de taille et de charge différentes, la trypsine et l'uréase, afin de mettre en évidence le rôle de la localisation des enzymes dans le matériau (modification de surface ou dans les pores). La stabilité au cours du temps du stockage a été étudié et a montré que l'immobilisation des enzymes dans des couches de polyélectrolytes améliore leur stabilité de façon très significative.

Abstract (sommario):

As doenças raras são epidemiologicamente caracterizadas por ocorrerem entre 0,65-1:1.000 indivíduos. Houve importante incremento no surgimento de tratamentos específicos para muitas destas condições a partir da publicação de legislações específicas em diferentes países (sendo o pioneiro em 1983 nos EUA o chamado 'Orphan Drug Act'). Dentre as doenças que dispõem atualmente de tratamento específico está a Doença de Fabry, uma doença genética classificada erro inato do metabolismo do grupo das doenças Lísossômica se caracterizada pelo acúmulo de glicoesfíngol ipídíos no endotélio vascular, o que

Abstract (sommario):

Enzyme technology is widely regarded as an exciting new technology possessing great opportunities for commercial interests and is one of a small group of key technologies singled out by the Science Research Councils during the 1960's as worthy of special support. In this thesis I outline the basic characteristics of this technology analysing the nature of the Government's policy towards it. The approach I have chosen requires an in depth analysis of the innovation process for enzymes which forms the basis for a model. This model is then used to focus on aspects of the UK science policy towards

Abstract (sommario):

Färgning av polyester (PET) sker i temperaturer omkring 130℃ och som en följd av den höga värmen migrerar oligomerer ut ur PET-fibern. Dessa oligomerer skapar därefter problem i form av vita fällningar och avlagringar, som leder till en reducering av maskinernas effektivitet, samt försämring av materialets utseende. En vanligt förekommande metod för att begränsa problemet är att tillsätta hjälpkemikalier i färgbadet. Novozymes A/S hävdar att genomförda studier med PET-garn och enzymet cutinase NS59038 har visat en minskning av det vita damm som kan ses på garnet i samband med migration av olig

Abstract (sommario):

L'environnement opératoire dans les domaines alimentaire et médical permet aux bactéries de se fixer et de se développer sur les surfaces, ce qui entraîne la formation de biofilms bactériens pathogènes et résistants. Ces structures pathogènes sont responsables de nombreuses maladies d'origine alimentaire et d'infections associées aux soins. Par conséquent, pour lutter contre ce fléau de santé publique, plusieurs stratégies ont récemment été proposées, notamment l'élimination chimique et mécanique. Ce travail présente les différents facteurs qui influencent l'adhésion bactérienne et la formatio
