1. 1. Bioprocess Monitoring and Control in Pseudomonas cepacia and recombinant Escherichia coli cultivations

   Författare :Anita Tocaj; LTH Ingenjörshögskolan vid Campus Helsingborg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein L; expanded bed; flow-injection analysis; recombinant protein production; acetic acid; on-line measurements; Pseudomonas cepacia; recombinant Escherichia coli; Fed-batch cultivations; control strategies; xylanase deletion derivatives from Rhodothermus marinus; Biotechnology; Bioteknik;

   Sammanfattning : The control of cultivation conditions and its influence on growth and production have been investigated. The use of fed-batch processes have been demonstrated for several cultivation systems and so has the use of different control signals in these systems. LÄS MER

3. 2. Chiral building blocks for synthesis of pine sawfly sex pheromones Enantioselective Lipase Catalysed Acylations and Esterifications of Primary Alcohols and Acids and Synthesis of the Sex Pheromone of the Pine Sawfly Microdiprion pallipes

   Författare :Ba-Vu Nguyen; KTH; []
   Nyckelord :lipase; Pseudomonas cepacia; Candida rugosa; enantioselective; enantiomeric ratio; primary 2-methylalcohol; substituted-methylcarboxylic acid; pine sawfly; Microdiprion pallipes; sex pheromone; 3; 7; 11-trimethyl-2-tridecanol; stereoisomer;

   Sammanfattning : This thesis describes the development of new methods for thepreparation of enantiomerically pure methyl branched alkylcompounds and their use as building blocks in the synthesis ofstereoisomerically pure pheromones of pine sawflies.The high regioselectivity, enantioselectivity and activityof lipases in organic solvent in conjunction withenvironmentally compatible reaction conditions have madelipase-catalysed synthesis an attractive alternative toconventional synthetic methods in organic chemistry.

4. 3. Bacterial colonisation and infection of the lower airways in cystic fibrosis : a microbiological and clinical study

   Författare :Ferenc Karpati; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :cystic fibrosis; sputum; Pseudomonas aeruginosa; Stenotrophomonas maltophilia; Burkholderia cepacia; PCR; AP-PCR; 16S RNA gene; DNA sequencing; heterogeneity; TNF-[alpha]; IL-8; ibuprofen;

   Sammanfattning : Pulmonary deterioration has remained the major cause of mortality in cystic fibrosis (C17) patients despite the considerable improvement of their survival due to more efficient therapy and centralised care. The progression of the CF lung disease is correlated to inflection with a limited number of colonising bacterial species. LÄS MER

5. 4. Enzymatic synthesis of lipids containing omega-3 fatty acids

   Författare :Ann-Marie Lyberg; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzymologi; Proteiner; enzymology; Proteins; Enzymes; DHA; EPA; Biotechnology; Bioteknik;

   Sammanfattning : Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 fatty acids, which have health promoting effects. Since they are highly prone to oxidation, they should be protected, in particular DHA. LÄS MER

7. 5. Stereoselective syntheses of semichemicals : Applications in ecological chemistry

   Författare :Ellen M. Santangelo; Anna-Karin Borg-Karlsson; Olov Sterner; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; synthesis; semiochemical; pheromone; Lepidoptera; diene; Organisk kemi; Organic chemistry; Organisk kemi;

   Sammanfattning : This thesis describes the syntheses of semiochemicals and their applications in the development of control methods for pest insects. The compounds synthesized are divided into three groups: 1) Lepidoptera pheromones; 2) methyl substituted chiral pheromones and 3) aphid pheromones. LÄS MER
