  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. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Linnéa Eriksson; [2023-04-20]
    Keywords : soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

    Abstract : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. READ MORE

  4. 3. Quality of Spent Mushroom Compost Amended with Organic Material- Effect on Nutrient Content and Plant Growth

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

    Author : Rasha Kamel; [2023]
    Keywords : Apple Waste; Wood Chips; Microbial Content; pH; Pseudomonas; General Bacterial Flora; General Fungal Flora; Electrical Conductivity; Nutrient Content; Bulk Density; Porosity; Water Holding Capacity;

    Abstract : Peat, as a non-renewable growing media, poses environmental concerns due to extraction and decomposition processes, leading to increased greenhouse gas emissions. Alternatives growing media with potential to replace or reduce the use of peat are of great need. READ MORE

  5. 4. Review of pH recommendations for soilless cultivation systems

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Elric Fabricius; [2023]
    Keywords : soilless cultivation; hydroponics; aeroponics; NFT; nutrient film technique; DWC; deep water culture; pH; nutrient solution; speciation; availability; biomass production;

    Abstract : Our human population is growing, and with that, so is our demand for food, food that today still is not a guarantee for all of us. To help increase global food security, the diversification of our food production through the implementation of soilless, hydroponic cultivation systems has been suggested. READ MORE

  6. 5. Explicit consideration of microbes in quantification of gross N rates based on N-tracing model

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Tsai-wei Tang; [2022-01-26]
    Keywords : N-tracing model; microbial biomass; gross N quantification; organic N; mineralization; immobilization;

    Abstract : When studying the nitrogen cycle in soils, the principle of 15N isotope dilution and enrichment is commonly used to measure gross N transformation rates. The measuring data of both organic and inorganic nitrogen substrates are therefore be analysed by Ntrace model. READ MORE
