1. 11. Metabolic Engineering of Disaccharide Catabolism for Polysaccharide Formation in Lactococcus lactis and Streptococcus thermophilus

   Författare :Fredrik Levander; Institutionen för immunteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; metabolic engineering; exopolysaccharide; polysaccharide; disaccharide; Streptococcus thermophilus; lactic acid bacteria; Lactococcus lactis; Biochemical technology; Biokemisk teknik; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Exopolysaccharides (EPSs) produced by the lactic acid bacteria (LAB) Lactococcus lactis and Streptococcus thermophilus are important for the rheological behaviour and texture of a variety of fermented food products. Furthermore, EPSs from food-grade LAB have potential as food additives and functional food ingredients with both health and economic benefits. LÄS MER

3. 12. Influence of strain, feed profile and cultivation technique on the lipid structure and membrane function in Escherichia coli

   Författare :Atefeh Shokri; KTH; []
   Nyckelord :Escherichia coli; phospholipid and fatty acid regulation. fed-batch; continuous cultivation; leakage; protein transport;

   Sammanfattning : The phospholipid and fatty acids content of the Escherichiacoli membrane were investigated during changes of feed rate,cultivation technique and host strains.During continuous cultivation it was shown that the leakageof periplasmic protein to the medium had an optimum at 0.3 h-1,resulting in transport of 20% of the total recombinant product.

4. 13. Regulation of metabolic events during embryo development in Norway spruce (Picea abies L. Karst)

   Författare :Edward Businge; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : The overall aim of this thesis was to identify and characterize metabolic and biochemical events that are involved in regulation of embryo development in Norway spruce. Embryogenesis involves coordination of multicellular patterning events which are critical for establishment of the apical-basal plan of the plant. LÄS MER

5. 14. Structural Studies of Binding Proteins: Investigations of Flexibility, Specificity and Stability

   Författare :Ulrika Magnusson; Sherry L. Mowbray; Anthony J. Wikinson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Periplasmic binding protein; X-ray crystallography; conformational change; acidophile; protein specificity; protein structure; Molekylärbiologi; Molecular biology; Molekylärbiologi;

   Sammanfattning : Binding proteins are present both in gram-negative and gram-positive bacteria. They are the recognition components of the ABC transport systems that transport different nutrients into the cell, and are in some cases also involved in chemotaxis. LÄS MER

7. 15. Dynamic regulation of the Mig1 transcriptional repressor under glucose de/repression

   Författare :Sviatlana Shashkova; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cell signalling; glucose repression; Mig1; phosphorylation; Saccharomyces cerevisiae;

   Sammanfattning : The budding yeast Saccharomyces cerevisiae AMP-activated protein kinase/SNF1 is a member of a highly conserved protein family present in all eukaryotes. Snf1 regulates energy homeostasis; in yeast, it is best-known for its role in cellular adaptation to glucose limitation. LÄS MER
