1. 1. Glycoside hydrolases from Rhodothermus marinus Modular organisation and structure-function relationships

   Detta är en avhandling från Maher Abou Hachem, Kämnärsvägen 13, E105, 226 46 Lund, Sweden

   Författare :Maher Abou-Hachem; Lund University.; Lunds universitet.; [2003]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium-binding; modular; endoglucanase; thermostable; CBM; xylanase; Biotechnology; Bioteknik;

   Sammanfattning : The thermophilic bacterium Rhodothermus marinus produces several thermostable glycoside hydrolases. The studies presented in this thesis were performed on two enzymes, belonging to glycoside hydrolase families 10 and 12, produced by this microorganism. The family 10 xylanase, Xyn10A, is modular in architecture consisting of five domains or modules. LÄS MER

3. 2. Enzymatic Synthesis of Mixed Acid Phospholipids

   Detta är en avhandling från Department of Biotechnology, Lund University

   Författare :Dietlind Adlercreutz; Lund University.; Lunds universitet.; [2002]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lysophosphatidylcholine; phosphatidylcholine; acyl migration; equilibrium; organic solvent; lipase; phospholipase; Biotechnology; Bioteknik;

   Sammanfattning : Mixed acid phospholipids are valuable compounds, which are used mainly in membrane- and lipoprotein research and in liposome technology. The chemical synthesis of these special lipids is rather difficult and involves both toxic chemicals and harsh reaction conditions, which makes the products less attractive for medical and biological applications.

   Sammanfattning : Ore-mining, metallurgy and other industrial activities represent the source of heavy metal and radionuclide contamination in terrestrial and aquatic environments. Physico-chemical processes are employed for heavy metal removal from industrial wastewater. LÄS MER

5. 4. Colonisation and PAH degradation by wood-rotting fungi in contaminated soil

   Detta är en avhandling från Department of Biotechnology, Lund University

   Författare :Erik Andersson; Lund University.; Lunds universitet.; [2001]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; agricultural hydrology; Soil Science; Bioteknik; Biotechnology; PLFA; PAH metabolites; PAH; degradation; contaminated soil; soil; brown-rot fungi; white-rot fungi; Colonisation; fungal growth; Lantbrukshydrologi; marklära; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Sammanfattning : Bioremediation of soils is considered a low-cost alternative to other remediation techniques. Its ability to remove a number of different pollutants has been demonstrated, relying mainly on the activities of indigenous soil bacteria. LÄS MER

7. 5. Protein Recovery Using Simulated Moving Bed Technology and Macroporous Chromatographic Support Material

   Detta är en avhandling från Department of Biotechnology, Lund University

   Författare :Jonatan Andersson; Lund University.; Lunds universitet.; [2007]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; Chromatography; Simulated Moving Bed; Protein;

   Sammanfattning : Due to its gentle and high resolving power, chromatography is the work horse within protein separation. Still it is an expensive method due to low productivity, diluted product streams, large waste streams and expensive support material. This limits its potential use to areas of high price products.
