  1. 6. Legacy effects of temperature alterations on microbial resistance and resilience to drying and rewetting

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Franklin Lee Harris; [2023]
    Keywords : microbial ecology; soil; carbon dynamics; high latitudes; climate change; moisture stress; isotopes; respiration; trait based ecology; soil microbes; Environmental Changes in High Latitudes EnCHIL ; Earth and Environmental Sciences; Biology and Life Sciences;

    Abstract : With warming in soils due to climate change, a series of secondary factors arise, which have multifaceted effects on soil microbial communities. Of these, alterations to soil moisture are among the most crucial to understanding how microbial functions will change in the face of climate change. READ MORE

  3. 7. 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

  4. 8. Some Like It Hot: Pre-heating Prior to Bioreactor Treatment Enhances Nitrogen Removal From Mine Drainage

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Laura Nina Bettoni; [2022]
    Keywords : denitrification; nitrate removal; temperature; woodchip bioreactor; waste rock leachate;

    Abstract : Ammonium-nitrate based explosives (NH4NO3) used within the operations of Kiruna iron ore mine release nitrate (NO3-) into the environment, potentially having adverse effects on local river-systems. One way of reducing NO3- impacts to the environment is through a woodchip denitrifying bioreactor (DBR). READ MORE

  5. 9. Biochar and Hemp as Peat Substituents in Horticultural Substrates and Their Effects on Presence of Microbiota

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

    Author : Louise Hagbard; [2022]
    Keywords : biochar; hemp; Cannabis sativa; peat reduction; peat; microbiome; fibers; substrate; growing media; Trichoderma; Pseudomonas; Lactuca sativa;

    Abstract : The extraction of peat has been shown to have a detrimental impact on the environment in several ways, including through emissions of greenhouse gases but also through a negative impact on fragile habitats, ecosystems, and ecosystem services. The horticultural sector is a major user of peat products and thus contributes to both emissions and habitat changes. READ MORE

  6. 10. Developing a Method to Study the Impact of Microbial DNA on the Brain Related to Alzheimer’s Disease – Can Food Make a Change?

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Fuh-Tzu Yang; [2022]
    Keywords : DNA extraction; Microbiome DNA enrichment; Host DNA depletion; 16S rRNA sequencing; Alzheimer’s disease; Gut-brain axis; Microbiota; Microbial DNA; Black currant; Applied Nutrition and Food Chemistry; Medicine and Health Sciences;

    Abstract : Understanding the gut-brain-microbiota axis can help us provide a new tool to manage conditions such as Alzheimer’s. However, a major challenge is selectively amplifying the bacterial DNA which is present at a much lower level than the host DNA. READ MORE
