  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

  2. 2. Microalgae – The new green? : biochemical composition, cultivation and extraction methods

    University essay from SLU/Department of Molecular Sciences

    Author : Ida Åkerberg; Christian Nordqvist; [2021]
    Keywords : microalgae; food; growth conditions; biochemical compounds; extraction;

    Abstract : Microalgae are a promising source of high value compounds for the food industry with both nutritional and health-beneficial qualities with potential to meet the dietary demand of the growing population. Microalgae are highly adaptive towards environmental stresses which is used as important tool for manipulation of the biomass for enhancement of metabolites. READ MORE

    Author : Miranda Blad; [2019]
    Keywords : tillväxtfrämjande; antibiotika; produktionsdjur;

    Abstract : Antibiotika har använts inom djurproduktion i tillväxtfrämjande syfte sedan den effekten uppdagades för över 50 år sedan. Med en ökande resistensproblematik har dock användningen ifrågasatts och i stora delar av världen även förbjudits. READ MORE

  4. 4. Probabilistic ecological risk assessment of secondary poisoning from DDT

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Alice Rundegren; [2019]
    Keywords : probabilistisk riskbedömning; toppredatorer; DDT; diklordifenyltrikloretan; plantskola; skogsplantskola; artkänslighetsfördelning; bioackumulering; förorenad mark; indirekt exponering; Monte Carlo simulering; probabilistic risk assessment; plant nursery; species sensitivity distribution; polluted soil; indirect exposure; bioaccumulation; Monte Carlo simulation; dichlorodiphenyltrichloroethane; Earth and Environmental Sciences;

    Abstract : Although prohibited since decades, dichlorodiphenyltrichloroethane (DDT) and its metabolites still remain in the soil and pose a threat to ecosystems, where especially birds are susceptible to toxic effects. In this thesis, a model developed in the 1990s was used and updated in order to estimate the risks of DDT to top predators at a forest-plant nursery site. READ MORE
