11. Specific Precipitation of Biomolecules Using Synthetic Polymers
Sammanfattning : Purification is a very important stage in biotechnological processes. The traditionally used precipitation techniques are generally nonspecific and thus one or more chromatographic steps are normally required. There is thus a need for new approaches to improve existing techniques. LÄS MER
12. Selection of Resistance at very low Antibiotic Concentrations
Sammanfattning : The extensive medical and agricultural use and misuse of antibiotics during the last 70 years has caused an enrichment of resistant pathogenic bacteria that now severely threatens our capacity to efficiently treat bacterial infections. While is has been known for a long time that high concentrations of antibiotics can select for resistant mutants, less is known about the lower limit at which antibiotics can be selective and enrich for resistant bacteria.

13. Primary Recovery of Biologically Active Compounds Using Macroporous Monolithic Hydrogels
Sammanfattning : The completion of sequencing of human and other mammalian genomes opens a new era for drug development. New approaches have been proposed for tackling diseases such as development of small molecule therapies based on understanding of human genome and proteome, new proteinous based therapies, where the therapeutic protein can inhibit or modify a certain metabolic pathway or DNA-based therapies delivering a gene into the cell (e.

14. Chitosan Polyplexes as Non-Viral Gene Delivery Systems : Structure-Property Relationships and In Vivo Efficiency
Sammanfattning : The subject of this thesis was to develop and optimize delivery systems for plasmid DNA (pDNA) based on biocompatible polymers, in particular chitosan, suitable for non-viral gene therapy. At the onset of this thesis, studies had reported conflicting results on the efficiency of chitosan-based gene delivery systems. LÄS MER
15. Global regulatory factors that impact metabolic and lifestyle choices in Pseudomonas putida
Sammanfattning : Pseudomonas putida strains have a broad metabolic capacity and are innately resistant to many harmful substances – properties that make them of interest for a number of industrial and biotechnological application. They can rapidly adapt to changes in physico-chemical parameters in the soil and water environments they naturally inhabit. LÄS MER
