1. Precipitation and separation of lignin from kraft black liquor
Sammanfattning : .... LÄS MER
2. Protein isolation from herring (Clupea harengus) using the pH-shift process - Protein yield, protein isolate quality and removal of food contaminants
Sammanfattning : Herring (Clupea harengus) contain valuable proteins but is difficult to process into high-quality foods due to its small size and high content of bones, heme-proteins and lipids. Herring is among the most abundant fish species in the world, but is currently utilized largely for fish meal and oil production. LÄS MER
3. Fractionation of lipids and protein from the microalga Nannochloropsis oculata
Sammanfattning : To feed Earth’s growing population, microalgae have been proposed as a source of protein and long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFAs). Currently, microalgae are mainly sold either as whole biomass, or the economically valuable LC n-3 PUFA fraction is extracted with organic solvents. LÄS MER
4. 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
5. Precipitation of Kraft Lignin from Aqueous Solutions
Sammanfattning : One way of improving the materials yield of a kraft paper pulp process, and simultaneously providing the industry with aromatic macromolecular structures, is to extract lignin from the black liquor. This can be done by lowering the pH of the black liquor, which will result in the precipitation of the lignin. LÄS MER
