3. 7. Heterologous expression and characterization of xyloglucan endotransglycosylases from Populus tremula x tremuloides

   Författare :Åsa Kallas; KTH; []
   Nyckelord :xyloglucan endotransglycosylase; transglycosylation; hybrid aspen; cell expansion; heterologous expression; Pichia pastoris; N-glycosylation; X-ray crystallography;

   Sammanfattning : Xyloglucan endotransglycosylases (XETs) are enzymes involvedin the reorganization of the primary cell wall. This thesisdescribes several aspects of XET16A from hybrid aspen (Populustremula x tremuloides). The gene was isolated from the hybridaspen cDNA library and the protein was expressed heterologouslyin the methylotrophic yeast Pichia pastoris. LÄS MER

4. 8. Investigation of a Biofilm Reactor Model with Suspended Biomass

   Författare :Alma Masic; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wall attachment; suspended growth; substrate removal; reactor; biofilm; CSTR; mathematical model; MBBR; nitrification; optimization;

   Sammanfattning : Biofilms are compact, sessile microbial communities that attach to surfaces in aqueous environments. In wastewater treatment, they are especially important for removal of phosphorus and nitrogen, which, if released into a receiving water body, can cause severe eutrophication. LÄS MER

5. 9. Hollow Cathode Deposition of Thin Films

   Författare :Lars-Erik Gustavsson; Ladislav Bárdoš; Hana Baránková; Claes Nender; Uppsala universitet; []
   Nyckelord :Electronics; Hollow cathode; Hybrid plasma; PVD; TiN films; Ferromagnetic substrates; Magnetized plasma; CrN films; Elektronik;

   Sammanfattning : Thin films of metals and compounds have a very wide range of applications today. Many of the deposition methods used for the production of such films utilize plasma to support the growth the film, e.g. by the supply of energy and the enhancement of reactivity. LÄS MER

7. 10. Functionalization and Characterization of Carbon Based Nanomaterials for Electronics, Composite and Biomedical Applications

   Författare :Nan Wang; Chalmers tekniska högskola; []
