  1. 16. Development of a shake flask method suitable for effective screening of Escherichia coli expression constructs

    University essay from KTH/Skolan för bioteknologi (BIO)

    Author : Klara Andersson; [2011]
    Keywords : E. coli; expression; process development; screening; recombinant protein;

    Abstract : Screening of expression constructs suitable for protein pharmaceuticals is often done in batch cultivations. But the production of the recombinant protein is made during fed-batch cultivations. READ MORE

  3. 17. Separate Hydrolysis and Fermentation of Pretreated Spruce

    University essay from Institutionen för fysik, kemi och biologi

    Author : Josefin Axelsson; [2011]
    Keywords : lignocellulosic ethanol; softwood; SHF; enzymatic hydrolysis; cellulases; end product inhibition;

    Abstract : Bioethanol from lignocellulose is expected to be the most likely fuel alternative in the near future. SEKAB E-Technology in Örnsköldsvik, Sweden develops the technology of the 2nd generation ethanol production; to produce ethanol from lignocellulosic raw material. READ MORE

  4. 18. Evaluation of gene amplification for development of high producing biopharmaceutical cell lines

    University essay from Akademin för hållbar samhälls- och teknikutveckling

    Author : Ellen Gustafsson; [2010]
    Keywords : ;

    Abstract : It is crucial to have a high producing stable cell line to be able to produce recombinant proteins from mammalian cells in large scale for clinical trials. The aim of this study has been to evaluate steps in a process platform for development of high producing sable cell lines with respect to time and titer. READ MORE

  5. 19. Probing Control in B. licheniformis Fermentations

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Ola Johnsson; [2010]
    Keywords : Technology and Engineering;

    Abstract : In industrial biotechnical processes in fed-batch mode it is desirable to keep a high feed rate in order to achieve a high production rate, while simultaneously avoiding overflow metabolism. This means that the optimum of the process is close to the point where it risks crashing due to the effects of overflow metabolites. READ MORE

  6. 20. Design and application of software sensors for monitoring of fed-batch cultivations containing recombinant Escherichia coli

    University essay from Institutionen för fysik, kemi och biologi

    Author : Cyrus Djahedi; [2010]
    Keywords : ;

    Abstract : Bioprocesses are industrial processes that use living cells to produce desired products. These processes are complex and require advanced monitoring and control in order to reach their highest potential. Software sensors are a potent tool for real time monitoring and control of bioprocesses. READ MORE
