  1. 16. Multivariate monitoring, modelling and control for stabilization of bioprocesses

    Author : Christian Cimander; Gunnar Lidén; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The obstacles to overcome low reproducibility and stability of bioprocesses are numerous. Underlying biochemical processes are inherently non-linear, complex and subject to shifting initial conditions. Problems with high variability are also associated to production strains and scale-up of a bioprocess to largescale bioreactors. READ MORE

  3. 18. Physiological Engineering of Xylose Utilisation by Recombinant Saccharomyces cerevisiae

    Author : Nina Quednau Meinander; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein burden; physiology; fed-batch fermentation; chemostat; recombinant Saccharomyces cerevisiae; ethanol; xylose; xylitol; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Xylitol production by recombinant, XYL1-expressing Saccharomyces cerevisiae was investigated in fed-batch fermentation using different cosubstrates for growth, and generation of reduced cofactors and maintenance energy. Xylose was converted into xylitol with 1:1 yield. READ MORE

  4. 19. The Technology and Economy of Farm-Scale, High-Solids Anaerobic Digestion of Plant Biomass

    Author : Mattias Svensson; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; farm-scale; Bioteknik; farmhouse construction; Lantbruksteknik; Biotechnology; agricultural machines; kontroll av utsläpp; Agricultural engineering; Miljöteknik; pollution control; Environmental technology; Lantbruksekonomi; straw bed priming; stratified bed digesters; nitrogen recycling; greenhouse gases; Sweden; Agricultural economics; sequential single-stage fed-batch; ley crops; sustainability; wheat straw; sugar beet tops; crop residues; high-solids; economy; Anaerobic digestion; biogas upgrading;

    Abstract : Anaerobic digestion is a microbially mediated process occurring in nature in the absence of oxygen and other non-carbonaceous electron acceptors. The majority of the carbon of the organic matter degraded in the process is transformed into carbon dioxide and methane. READ MORE

  5. 20. Analytical tools for monitoring and control of fermentation processes

    Author : Heléne Sundström; Sven-Olof Enfors; Carl-Fredrik Mandenius; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Escherichia coli; flow cytometry; software sensors; viability; inclusion bodies; biomass; specific growth rate; stress; population heterogeneity; process analytical technology.; Biochemical process engineering; Biokemisk och bioteknisk processteknik;

    Abstract : The overall objective of this work has been to adopt new developments and techniques in the area of measurement, modelling and control of fermentation processes. Flow cytometry and software sensors are techniques which were considered ready for application and the focus was set on developing tools for research aiming at understanding the relationship between measured variables and process quality parameters.
