1. 21. Endoglucanase and Mannanase from Blue Mussel, Mytilus edulis: Purification, Characterization, Gene and Three Dimensional Structure

   Författare :Bingze Xu; Folke Tjerneld; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; Bioengineering; Bioteknik; Surface Biotechnology; ytbioteknik;

   Sammanfattning : Two polysaccharide-degrading enzymes (endo-1,4-D-glucanase and β-mannanase) from blue mussel, Mytilus edulis, have been purified to homogeneity using a combination of several chromatographic steps. Each enzyme has been characterized with regard to its molecular weight, isoelectric point, pH and temperature stability, pH and temperature optimum and substrate specificity. LÄS MER

3. 22. Interfacial Properties of Film Forming Proteins and their Layer-by-Layer Assembly with Nanoparticles

   Författare :Olga Krivosheeva; Per Claesson; Thomas Arnebrant; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein adsorption; mussel adhesive protein; Mefp-1; hydrophobins; HFBI; HFBII; adsorption kinetics; layer-by-layer; stability; cross-linking; zeta-potential; dual polarization interferometry; quartz crystal microbalances;

   Sammanfattning :  The aim of this thesis work was to investigate the interfacial properties of film forming proteins, stability of the layers created by them, and their interactions with nanoparticles. Mussel adhesive protein (Mefp-1) and hydrophobins (HFBI and HFBII) were the three main proteins used. LÄS MER

4. 23. Exploring phenomena that affect the fate and impact of radioactive materials in the blue mussel

   Författare :Benedict Jaeschke; Clare Bradshaw; Andrew Turner; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radioecology; ionising radiation; environmental protection; Mytilus edulis; bioaccumulation; dose-response; ecotoxicology; tritium; particle; hypoxia; marin ekotoxikologi; Marine Ecotoxicology;

   Sammanfattning : Current protection of the marine environment from radiation is based largely on measuring, estimating and modelling accumulation and impact(s) of radionuclides in a few marine species. Using a relevant marine organism, this thesis focusses on investigating some poorly described phenomena that could cause deviations from predicted measurements. LÄS MER

5. 24. Ecological and physiological aspects of contaminant accumulation and transport by the filter-feeding mussel, Mytilus edulis

   Författare :Mikael Björk; Jussi Kukkonen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Marine Ecotoxicology; marin ekotoxikologi;

   Sammanfattning : This thesis examines the influence of food availability on the bioaccumulation kinetics and the transport of hydrophobic organic contaminants (HOCs) by the Baltic Sea blue mussel, Mytilus edulis. In laboratory studies, food availability was found to significantly modify the rate of physiological processes involved in filter-feeding. LÄS MER

7. 25. Parasite host interaction between the freshwater pearl mussel (Margaritifera margaritifera) and brown trout (Salmo trutta) – the impact from glochidia larvae on the host

   Författare :Niklas Wengström; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Parasites can modulate the physiology and behavior of the hosts to enhance their chances to complete their life cycle. The numerous freshwater bivalves of the order Unionoida all have a parasitic larval stage, also known as glochidia, parasitizing fish hosts. LÄS MER
