  1. 1. Screening of HETP test conditions and resin storage solutions for HIC

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Analytisk farmaceutisk kemi

    Författare :Lise-Lotte Ronnerfors; [2023]
    Nyckelord :Hydrophobic Interaction Chromatography; Pfizer Health AB; Column packing;

    Sammanfattning : Hydrophobic interaction chromatography (HIC) is a common purification method for biological drug substances. For continuous monitoring the quality of the purification, a column performance test is carried out to test the packing of the resin. LÄS MER

  2. 2. Production of succinic acid by Actinobacillus succinogenes in attached-growth bioreactors and dynamic modelling of biofilm formation

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Henrik Östberg; [2023]
    Nyckelord :Actinobacillus succinogenes; Succinic acid; Biofilm; Attached-growth bioreactor; Dynamic modelling; Cell cultivation; Applied microbiology; Biology and Life Sciences;

    Sammanfattning : Actinobacillus succinogenes is a microorganism is a very efficient producer of succinic acid, a chemical with a wide range of industrial applications. The bacterium is prone to form biofilm, a flocculation of cells attached to a surface. LÄS MER

  3. 3. Orbit-simulator for downstream processes

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Andreas Malmström; [2022]
    Nyckelord :Chemical engineering; Process simulation; Downstream processes; Orbit; Preparative chromatography; Python; Lumped Rate Models; Technology and Engineering;

    Sammanfattning : In an ever more digitilized society, the transition is palpable also in the pharmaceutical industry. The control system Orbit was developed at the department of chemical engineering at Lund University, to be able to automate downstream processes based on the ÄKTA-system. LÄS MER

  4. 4. Acid retardation : recovery and recycling of acid and metal

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Cecilia Bood; [2020]
    Nyckelord :Acid retardation; Ion exchange; Pickling; Stainless steel;

    Sammanfattning : During the production of steel, an oxide scale is formed on the surface and to achieve anadequate quality of the surface the scale needs to be removed. Acid pickling is a surfacetreatment where the oxide scale is removed by acid. LÄS MER

  5. 5. Methyl salicylate production by the fungus Ophiostoma pluriannulatum isolated from Pine Weevil frass

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemivetenskap (CHE)

    Författare :Emil Norin; [2011]
    Nyckelord :Ophiostoma pluriannulatum; Methyl salicylate; SPME; volatiles; antifeedant;

    Sammanfattning : One great issue of reforestation is the infestation of pest insects. The pine weevil (Hylobius abietis L.) is one of the economically most important pest insects in Europe and Asia. When insects feed on the trees the plants emit compounds that repel the insects. LÄS MER
