  1. 1. Optimization of a two-step anaerobic treatment of wastewater from the Pulp and Paper Industry

    University essay from KTH/Industriell bioteknologi

    Author : Sara Bard; [2022]
    Keywords : Wastewater treatment; biogas; methane; pulp and paper mill wastewater; wood raw material; anaerobic treatment; sulphate reduction; UAPB reactor; Vattenrening; biogas; metan; processvatten från pappers- och massaindustrin; träråvara; anaerob rening; sulfatreduktion; UAPB reaktor;

    Abstract : Under de senaste 30 åren så har antalet massa- och pappersbruk minskat medan den totala produktionen av massa och papper har ökat. En högre produktion per bruk tillsammans med en hårdare miljölagstiftning, sätter ett högre tryck på vattenreningen på varje bruk. READ MORE

  3. 2. Search for Preserved Methanogenic Organisms in Ophiolitic Rocks through Lipid Biomarker Analysis – Implications for Astrobiological Explorations

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Alexandra Zetterlind; [2020]
    Keywords : ophiolite; deep biosphere; archaea; methanogenesis; chemosynthesis; serpentinite-hosted ecosystems; lipid biomarkers; astrobiology; ofiolit; djupbiosfär; arkeér; metanogener; kemosyntes; serpentinit-drivna ekosystem; lipidbiomarkörer; astrobiologi;

    Abstract : Serpentinization is a metamorphic low-temperature geological process, involving a series of chemical reactions that hydrate ultramafic rocks into serpentines and other minerals such as magnetite and brucite. Moreover, the process produces heavily reducing and highly alkaline fluids together with molecular hydrogen (H2) and methane (CH4), which have the capacity to support chemosynthetic microbial life.

  4. 3. Spatial and temporal changes in microbial community composition in a full-scale woodchip bioreactor for treating mine water

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Felicia Wallnäs; [2020]
    Keywords : ;

    Abstract : Incomplete detonation of nitrogen-based explosives can lead to abundant levels of nitrate in mine groundwater. The possibility of reducing nitrogen levels from the wastewater through denitrification, anammox and DNRA has been investigated using a full-scale bioreactor. The bioreactor is situated subsurface and is filled with pine woodchips. READ MORE

  5. 4. Isolation and genomic characterization of three PHA degrading bacteria from the marine environment

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

    Author : Giulia Elli; [2019]
    Keywords : PHA; degradation of PHA; marine bacteria; sulphate reducing bacteria; SRB; SRM; biotechnology; bioteknik; Technology and Engineering;

    Abstract : The broader goal of this project was to investigate what kind of effects the accumulation of polyhydroxyalkanoates (PHA) in the marine environment might have on the microbial world. Bacteria were isolated from biofilms fouling PHA pellets placed in the sediment-water interface; the goal was to isolate PHA degraders that were also sulphate reducers. READ MORE

  6. 5. Årstidsdynamik för kvicksilver i ett sövattensediment

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Anna Karlsson; [2008]
    Keywords : kvicksilver; metylering; sediment; sjöar;

    Abstract : The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. READ MORE
