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

    University essay from Lunds universitet/Teknisk mikrobiologi

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

    Abstract : 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. READ MORE

  3. 2. Optimization of sterilization method for cultivation of filamentous fungi on lemon waste

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Oliver Conradsson; David Ljungberg; [2023]
    Keywords : Lemon waste; lemon waste; sterilization; autoclavation; fungal cultivation; bubble column bioreactor; fungal biomass Rhizopus delemar;

    Abstract : Consumption of citrus fruits and citrus juice production creates wastes, which could be valorized by using it for cultivating fungi. Before cultivation, the medium needs to be sterilized though autoclavation. Larger volumes used when autoclaving requires longer heating cycles and therefore runs the risk of degrading the medium to a greater extent. READ MORE

  4. 3. Simulation of bubbly flow in a flat bubble column

    University essay from Lunds universitet/Kemiska institutionen; Lunds universitet/Kemiteknik (CI)

    Author : Andreas Nygren; [2014]
    Keywords : Computational Fluid Dynamics; Bubble Column; Turbulence Modelling; Eulerian-Eulerian framework; Chemistry;

    Abstract : Numerical, transient simulations of a meandering bubble plume in a rectangular flat bubble column was carried out, using the commercial CFD package ANSYS Fluent 15 within the framework of a Eulerian-Eulerian description. A Sensitivity analysis of turbulence closure was performed using four turbulence models: standard, RNG, Realizable k − epsilon and the Reynolds stress model. READ MORE
