  1. 1. Geobacillus 7349 – A new potential biosurfactant producing microorganism

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Zhuoying Deng; [2023]
    Keywords : biosurfactant; rhamnolipids; HPLC; HPAEC-PAD; bacteria growth; downstream purification; liquid-liquid extraction; biotechnology; Chemistry;

    Abstract : The main aim of this master project is to find out whether strain Geobacillus 7349 can produce biosurfactant during their growth by extraction and characterization of the product. The other goal is to optimize the cultivation condition of the strain. READ MORE

  3. 2. Physiological adaptive mechanism to oxidative stress in Lactobacillus reuteri DSM 17938

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Julian David Rivera Ramirez; [2019]
    Keywords : Applied microbiology; Teknisk mikrobiologi; Biology and Life Sciences; Chemistry;

    Abstract : Probiotics are living microorganisms which could induce a potential health benefit to the host when consumed in adequate amounts. Among the different probiotics in the market, Lactobacillus reuteri strain DSM 17938 is a microaerophilic and heterofermentative organism that is able to tolerate high oxygen conditions compared with another L.

  4. 3. Investigation of growth modes of the lithoautotrophic bacterium Cupriavidus necator

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Raquel Perruca Foncillas; [2018]
    Keywords : applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : The microorganism Cupriavidus necator is a very interesting bacterium that has been established as a model microorganism for its capability to produce polyhydroxyalkanoates, more specifically polyhydroxybutyrate (PHB), a potential precursor/raw material for bioplastics. Lately, the scientific community has raised interest in the chemolithoautotrophic nature of C. READ MORE

  5. 4. Physiology of Caulobacter crescentus grown on different carbon sources

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Sara Lind Jónsdóttir Glaser; [2016]
    Keywords : aerobic cultivation; physical characterization; lignocellulosic biomass; xylose degradation; Weimberg; bioreactors; enzyme assays; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : Freshwater, obligate aerobic, Gram-negative bacterium Caulobacter crescentus strain CB2 is able to metabolise various types of carbon sources. In this degree project, growth characterization of C.crescentus was made on different substrates including glucose, xylose, and mannose using shake-flask cultivations and bioreactor experiments.

  6. 5. Aquaculture effluents as fertilizer in hydroponic cultivation : a case study comparing nutritional and microbiological properties

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Johan Lund; [2014]
    Keywords : Organic hydroponic; Aquaponic; Aquaculture; Plant nutrition; Microbial horticulture;

    Abstract : This paper evaluates the prospects for utilizing aquaculture effluents as a nutrient source in organic hydroponic, as is the case in aquaponics. The development of organic hydroponics is dependent on replacing synthetic fertilizers with organically derived nutrients, such as those found in aquaculture effluents. READ MORE
