  1. 21. Probing Control in B. licheniformis Fermentations

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Ola Johnsson; [2010]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Cyrus Djahedi; [2010]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  3. 23. Design and Application of Software Sensors in Batch and Fed-batch Cultivations during Recombinant Protein Expression in Escherichia coli

    Master-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Benedikt Warth; [2008]
    Nyckelord :Software sensor; Escherichia coli; Green fluorescence protein; Process analytical technology PAT ; Biomass; Metabolic stress;

    Sammanfattning : Software sensors are a potent tool to improve biotechnological real time process monitoring and control. In the current project, algorithms for six partly novel, software sensors were established and tested in a microbial reactor system. LÄS MER

  4. 24. Concentrating lignocellulosic hydrolysate by evaporation and its fermentation by repeated fedbatch using flocculating Saccharomyces cerevisiae

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Anahita Dehkhoda; [2008]
    Nyckelord :concentrating; lignocellulosic hydrolysate; evaporation; flocculating; yeast; fermentation; ethanol;

    Sammanfattning : In order to obtain a sugar concentration of more than 100g.l-1of fermentable sugars, aspruce wood hydrolysate was subjected to high pressure and vacuum concentration andthe fermentability of each hydrolysate was assessed by fermentation experiments withflocculating S. cerevisiae.

  5. 25. High-throughput Fed-batch Production of Affibody® molecules in a novel Multi-fermentor system

    Uppsats för yrkesexamina på grundnivå, Institutionen för fysik, kemi och biologi

    Författare :Johan Larsson; [2005]
    Nyckelord :Escherichia coli; fed-batch; Affibody® molecules; phosphogluconoylation;

    Sammanfattning : The present Master thesis describes the development and optimization of a fed-batch process for production of recombinant proteins in Escherichia coli BL21(DE3) in a multi-fermentor system. The system consists of six 1-liter fermentors, capable of producing 500-1500 μg/mL with present protocol. LÄS MER
