  1. 1. Macroalgae as feed supplement for reduction of methane emission in livestock : Overview of current knowledge and potential Nordic species

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

    Author : Hanna Silwer; [2018]
    Keywords : Asparagopsis taxiformis; bromoform; climate change; dairy industry; microbial ecosystem; secondary metabolites;

    Abstract : Climate change is a fact and production systems are in need of modernization and sustainable development. Methane is a problematic and potent greenhouse gas and is emitted as a natural byproduct from livestock metabolism. READ MORE

  3. 2. Emission of methane from tree stems in the Amazon basin : A study to investigate short temporal and spatial variability of methane emission of tree stems in the Amazon basin

    University essay from Linköpings universitet/Tema Miljöförändring; Linköpings universitet/Tema Miljöförändring

    Author : Magdalena Lindgren; Ida Pehrson; [2018]
    Keywords : Methane; tree stems; greenhouse gas; gas exchange; carbon cycle; seasonally flooded forests; short temporal variability; spatial variability; Amazon basin;

    Abstract : It is well known that methane (CH4) is emitted from soil, water and wetlands under anaerobic conditions through methanogenesis. CH4 is the final product of the anaerobic respiration of the microorganism methanogen. READ MORE

  4. 3. The effects of trace elements on the microbial communities of thermophilic biogas production

    University essay from SLU/Dept. of Microbiology

    Author : Robin Hagblom; [2016]
    Keywords : biogas; thermophilic; trace elements; ammonia; SAO; fhs;

    Abstract : The increasing need for alternatives to fossil fuels and traditional waste management systems can be simultaneously addressed by the production of biogas using organic waste as input material. The biogas produced can be used directly for energy production or upgraded to increase methane purity for use in the engines of motor vehicles. READ MORE

  5. 4. Sources of organic carbon fueling carbon emissions from tropical reservoirs

    University essay from

    Author : Gabriella Villamor Saucedo; [2016]
    Keywords : tropical reservoirs; decomposition; autochthonous carbon; allochthonous carbon; tropical macrophytes; methanogenesis; tropiska vattenkraftsmagasin; metangasproduktion; autoktont OM; alloktont OM; tropiska makrofyter;

    Abstract : For a sustainable energy supply, it is of importance to be aware about the environmental impacts from the different energy sources. Hydroelectric reservoirs in tropical areas have been found to emit more greenhouse gases (GHG) than reservoirs from boreal regions. READ MORE

  6. 5. Cleaning process of abattoir wastewater with focus on bacterial pathogens

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Johan Thorell; [2014]
    Keywords : Cleaning process; Abattoir Wastewater ; Bacterial pathogens;

    Abstract : This study was conducted at the City Abattoir in Kampala, Uganda to evaluate the cleaning process, with focus on bacterial pathogens, in a pilot scale integrated bioprocess. This consisted of four steps: anaerobic sequencing batch reactors; aerobic/anoxic sequencing batch reactors; a high performance temperature controlled methanogenesis digester and a constructed wetland.
