  2. 1. Fast isolation of proteins from bioreactors using affinity chromatography techniques

    Author : Eva Pålsson; Avdelningen för klinisk genetik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chromatography; protein purification; analyses; dispersion; chromatography matrices; Biochemistry; Biokemi; Metabolism; expanded bed; metabolism; Biotechnology; Bioteknik;

    Abstract : The purification of proteins from raw materials like fermentation broth and other biological sources usually involves several purification steps and is rather time consuming and expensive. This is a major concern in the production of many important protein products e.g. pharmaceuticals such as insulin and blood coagulation factors. READ MORE

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

    Author : Anita Tocaj; LTH Ingenjörshögskolan vid Campus Helsingborg; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Production and engineering of a xyloglucan endo-transglycosylase from Populus tremula x tremuloides

    Author : Maria Henriksson; Tuula Teeri; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; xyloglucan endo-transglycosylase; retaining glycoside hydrolase; glycosynthase; Pichia pastoris; fed-batch fermentation; expanded-bed adsorption; Plant biotechnology; Växtbioteknik;

    Abstract : The aim of this work was to develop a production process for the enzyme xyloglucan endo-transglycosylase from Populus tremula x tremuloides (PttXET16-34). The natural transglycosylating activity of this enzyme has previously been employed in a XET-Technology. READ MORE

  7. 5. Polyelectrolytes and Polycomplexes in Biotechnology

    Author : Maria Dainiak; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; expanded bed adsorption.; affinity precipitation; Fab fragments; monoclonal antibodies; glyceraldehyde-3-phosphate dehydrogenase; misfolded protein; chaperone; poly N-ethyl-4-vinylpyridinium bromide ; poly methacrylic acid ; poly acrylic acid ; Key words: polyelectrolyte; polyelectrolyte complexes; Biotechnology; Bioteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : Polyelectrolytes and polyelectrolyte complexes (PECs) are characterized by many useful properties that endow them with high potential in different areas of biotechnology. This thesis describes the development and analyses of some new systems and methods utilizing poly(acrylic acid) (PAA), poly(methacrylic acid) (PMA), poly (N-ethyl-4-vinylpyridinium bromide) (PEVP) and PMA-PEVP complexes.
