  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. 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

  4. 3. 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

  5. 4. 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.

  6. 5. Observation of methanogenesis and potential iron-dependent anaerobic oxidation of methane in old lake sediments, a study of two boreal forest lakes.

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Elias Broman; [2013]
    Keywords : Limnology; Lake; Sediment; Methane; Anaerobic oxidation;

    Abstract : Organic and inorganic carbon can enter inland waters in different ways, and often a considerable amount of this carbon is coming from terrestrial input. Once this terrestrial carbon enters a lake, the carbon may be degraded, mineralized or eventually buried in the sediment. READ MORE
