  1. 1. Biokinetic Characterization of Methane Oxidizing Microbiomes Co-metabolizing Trace Organic Chemicals

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Hugo Möller; [2024]
    Keywords : Methanotrophs; organic micropollutants; co-metabolism; biodegradation; applied microbiology; Earth and Environmental Sciences;

    Abstract : The presence of organic micropollutants (OMPs) in wastewater effluents is concerning, as they pose a threat to human and aquatic health. Biodegradation via methane-oxidizing bacteria (MOB) is an attractive option, as the method is cheap and effective. MOB can co-metabolize a variety of substrates, there among organic micropollutants.

  3. 2. Characterization of Compost from Reusable Industrial Streams: : physical, Nutrient, and Microbial Properties

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

    Author : Ellen Ek Moreau; [2023]
    Keywords : Spent mushroom compost; apple orchard waste; soil amendment; compost optimization; circular agriculture;

    Abstract : The increasing global population, combined with soil degradation, poses challenges to food security, and raises concerns about the excessive and long-term use of conventional fertilizers. Evaluating sustainable alternative by-products for their soil-improving properties could offer a potential solution, particularly for Swedish fruit producers who can tap into local waste streams as a circular source of plant nutrients.

  4. 3. Isolation of an ammonia-tolerant syntrophic butyrate-oxidizing bacterium originating from a thermophilic biogas digester

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Malin Tiefensee; [2023]
    Keywords : thermophilic; ammonia-tolerant; syntrophic butyrate-oxidizing bacterium;

    Abstract : Syntrophic relationships between fatty acid degrading bacteria and hydrogenotrophic methanogens are important for a well-functioning anaerobic degradation process during biogas production from organic waste material. This is particularly important in biogas processes fed protein-rich material as their degradation gives rise to high levels of ammonia, which inhibits many microorganisms. READ MORE

  5. 4. Reinforced Biodegradable Polymer Composite Material based on Japanese Washi Paper

    University essay from Uppsala universitet/Institutionen för kemi - Ångström

    Author : Lovisa Rova; [2022]
    Keywords : biodegradable; polymer; composite; paper-based; washi; poly butylene succinate ; biodegradation;

    Abstract : In this study, traditional Japanese washi paper was sandwiched with poly(butylene succinate)(PBS) in order to produce a paper-based composite material that can be biologically degraded. Specimens were prepared using a hot press, and the mechanical properties of the washi paperand the new composite material were investigated by tensile tests. READ MORE

  6. 5. Influence of permafrost disintegration on wetland carbon fluxes in Abisko, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Aida Esmailzadeh Davani; [2021]
    Keywords : Physical Geography; Ecosystem Analysis; Permafrost; CH4 flux; CO2 flux; Abisko; Wetlands; Earth and Environmental Sciences;

    Abstract : The northern permafrost regions are experiencing a rapid warming as surface temperatures are rising, causing a disintegration of permafrost and a deepening of the active layer (AL). This releases previously frozen carbon, making it available for decomposition by microbes. READ MORE
