1. Biocatalyst Engineering: Metabolic Engineering, Kinetic modeling and metagenomics applied to industrial biotechnology
Sammanfattning : Industrial biotechnology has been defined as the use and application of biotechnology for the sustainable processing and production of chemicals, materials and fuels. It makes use of biocatalysts such as microbial communities, whole-cell microorganisms or purified enzymes. LÄS MER
2. Trametes versicolor as biodegrader and biocatalyst when using lignocellulose for ethanol production
Sammanfattning : Energy consumption has increased rapidly during the last century due to population growth and greater industrialization. Lignocellulosic-based biofuels are being developed as alternatives to fossil fuels. For many years the question of how 5-carbon sugars in biomass are utilized in nature has been a vexed one. LÄS MER
3. Enantioenriched Cyanohydrins and Acetoxyphosphonates – Synthesis and Applications
Sammanfattning : In this thesis, the synthesis of enantioenriched compounds using novel methodologies that employ metal- and biocatalysis is described.In the first part, the synthesis of enantioenriched cyanohydrins, which are highly versatile synthetic intermediates, is described. LÄS MER
4. Engineered Yeast as Biocatalyst for Stereoselective reductions of Dicarbonyl Compounds
Sammanfattning : Chiral building blocks are needed in the chemical and pharmaceutical industries for the production of fine chemicals and pharmaceuticals. The utilisation of microorganisms and enzymes to perform stereoselective reductions of carbonyl compounds is an efficient and widely applied method for the generation of chiral molecules. LÄS MER
5. Improving the biocatalyst. Engineering of fungal oxidoreductases and thin-film electrodes for improvement of membraneless biofuel cells and carbohydrate biosensors
Sammanfattning : This thesis presents investigations for the improvement of electrical contact and catalytical properties of two fungal redox enzymes, cellobiose dehydrogenase (CDH) and pyranose dehydrogenase (PDH), with electrodes and the use of the prepared electrodes as carbohydrate biosensors and in enzymatic biofuel cells. The performance of enzyme modified electrodes can be improved in two ways, by modifying the bioelement or by modifying the electrode. LÄS MER
