2. 1. Large-scale Bioreactor Phenomena and Characteristics; Effects on E.coli fed batch fermentations on 30m3 scale

   Author : Gustav Silfversparre; KTH; []
   Keywords : Large-scale; E.coli; fed batch; concentration gradients; mixing;

   Abstract : Due to economical and practical limitations the fluiddynamics and mass transport properties are less optimal inlarge-scale bioreactors compared to lab-scale bioreactors. Incombination with the microbial reaction rates this creates amuch more dynamic environment for cells cultivated inlarge-scale bioreactors compared to lab-scale bioreactors. READ MORE

4. 2. Production of L-arginine by genetically modified Escherichia coli

   Author : Mireille Ginesy; Björn Alriksson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

   Abstract : In the recent years, the demand for environmental friendly produced L-arginine has risen with the increasing number of applications for this amino acid in pharmaceuticals, nutraceuticals, cosmetics, animal feed and fertilizers. Members of the Corynebacteriaceae family are usually used for microbial L-arginine production. READ MORE

5. 3. Production of L-arginine by Escherichia coli : Impact of genetic modifications, carbon and nitrogen sources

   Author : Mireille Ginesy; Ulrika Rova; Michael Sauer; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

   Abstract : In the recent years, the demand for environmental friendly produced L-arginine has risen with the increasing number of applications for this amino acid in pharmaceuticals, nutraceuticals, cosmetics, animal feed and fertilizers.Microbial production of L-arginine usually relies on Corynebacterium glutam-icum and Corynebacterium crenatum strains.

6. 4. 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

7. 5. Engineering and applications of surface displayed tyrosinase on Escherichia coli

   Author : David Hörnström; Antonius J. A. van Maris; Joachim José; KTH; []
   Keywords : Bioteknologi; Biotechnology;

   Abstract : The rise of biotechnology has provided a toolbox to deal with major challenges related to pollution and health. Microbial enzymes constitute powerful macromolecules with applications in environmental technology, and industrial and medical production. READ MORE
