  1. 11. Combined production of bioethanol and biogas from wheat straw

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Victor Gustafson; [2015]
    Keywords : lactic acid; chemical engineering; biogas; enzymes; enzymatic hydrolysis; energy recovery; ethanol red; bioethanol; wheat straw; steam pretreatment; inhibitors; kemiteknik; Technology and Engineering;

    Abstract : Currently the production cost of lignocellulosic ethanol is considered to be relatively high. Large fractions of the production cost come from the raw material and the energy consumed in the distillation. Therefore it is desirable to have a process that yields high concentration of ethanol and maximizes the utilization of the biomass. READ MORE

  3. 12. Evaluation of on-line cell viability and L-lactate measurements in soft sensor for mammalian cell cultures

    University essay from Linköpings universitet/Teknisk biologi; Linköpings universitet/Tekniska högskolan

    Author : Alexander Reissig; [2014]
    Keywords : hybridoma; B lymphocytes; batch reactor; soft sensor; lactate; L-lactate; radio-frequency impedance; BioSenz; enzyme thermistor; overflow metabolism;

    Abstract : Increasing demand on more effective cell culture reactors has driven optimization works to increase output of products. This has led to development of soft sensors that uses mathematical formulas to increase the available information for the parameters during runs. READ MORE

  4. 13. Process development for the production of a therapeutic Affibody® Molecule

    University essay from Institutionen för biologisk grundutbildning

    Author : Belinda Fridman; [2014]
    Keywords : Affibody® Molecule; HER3; EGFR; HER2; cancer therapy; process development; DOE; multivariate data analysis; E. coli; ABD; plasma half-life; thermolysis; fed-batch; gluconoylation; BL21 DE3 ; T7 expression system;

    Abstract : Recently HER3, member of the epidermal growth factor receptor family (EGFR), has been found to play a crucial role in the development of resistance towards inhibitors that are given to patients with HER1- and HER2-driven cancers. As HER3 is up-regulated or over-activated in several types of human cancers, it is of outmost importance that new innovative drugs target its oncologic activity. READ MORE

  5. 14. Medium optimization of an E.coli fed-batch culture for the production of a recombinant protein

    University essay from KTH/Skolan för bioteknologi (BIO)

    Author : Patsy Maria Engström; [2013]
    Keywords : Cultivation; fed-batch; E.coli; medium optimization; aminoacids; recombinant protein;

    Abstract : .... READ MORE

  6. 15. On-line control of glucose feeding in an Escherichia coli fed-batch cultivation expressing a recombinant protein.

    University essay from Teknisk biologi

    Author : Robert Gustavsson; [2011]
    Keywords : Soft sensors; Escherichia coli; Green fluorescent protein; Overflow metabolism and mixed acid fermentation; Glucose regulation;

    Abstract : Soft sensors have been suggested as potent tools for on-line estimations of critical bioprocess variables to be able to control the biological process in an as high extent as possible. The formation of inhibitory by-products in the form of organic acids, caused by an overflow of glucose, is a problem in most bioprocesses expressing recombinant proteins. READ MORE
