  1. 6. Wood-Decomposing Fungi: Soil colonization, effects on indigenous bacterial community in soil and hydroxyl radical production

    University dissertation from Microbial Ecology, Lund University

    Author : Karin Tornberg; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; hydroxyl radicals; fungal growth; interactions; soil colonization; bacterial community; soil; brown-rot fungi; wood-decomposing fungi; white-rot fungi; Ekologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The extracellular enzyme activities of wood-decomposing basidiomycetes are essential for wood degradation, but are also able to degrade various recalcitrant organic pollutants. The possible application of wood-decomposing fungi in bioremediation has increased the interest in understanding their growth and activity in soil. READ MORE

  2. 7. Interactions between ectomycorrhizal associations and bacteria

    University dissertation from ; Department of Forest Mycology and Plant Pathology, Swedish University of Agricultural Sciences

    Author : Srisailam Marupakula; Sveriges lantbruksuniversitet.; [2016]

    Abstract : Boreal forest podzol soils have vertically stratified horizons with different physico-chemical characteristics and high microbial diversity. Ectomycorrhizal fungi play key roles in accessing nutrients from both organic and mineral substrates. The role of associated bacteria in these processes is still poorly understood. READ MORE

  3. 8. Remediation of mercury contaminated soil and biological mercury methylation in the landscape

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jingying Xu; Stefan Bertilsson; Andrea Garcia Bravo; Dario Acha; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mercury contamination; Soil remediation; Methylmercury; Mercury methylation; hgcA; Community composition; Bacteria; Landscape; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : Accumulation of mercury (Hg) in soil originating from both natural and anthropogenic sources poses a major hazard to environmental and human health. Inorganic Hg(II) in soil can be transformed to highly toxic methylmercury (MeHg) mainly via methylating microorganisms. READ MORE

  4. 9. Phytoremediation of soil contaminated with petroleum hydrocarbons and trace elements

    University dissertation from Växjö : Linnaeus University Press

    Author : Charlotte Marchand; Hogland William; Hijri Mohamed; Bramryd Torleif; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Petroleum Hydrocarbon; Trace Elements; Gentle Soil Remediation Options; Polycyclic Aromatic Hydrocarbon; Respirometry; Ecopile; Bacteria; Fungi; Miljövetenskap; Environmental Science;

    Abstract : The rapid urbanization and industrialization has led to an increase of disposal petroleum hydrocarbons (PHC) and trace elements (TE) into the environment. These pollutants are considered as the most toxic contaminants in the world due to their persistence in the environment, and the long range of toxicological effects for living beings. READ MORE

  5. 10. Plant-associated soil communities Patterns, drivers and aboveground consequences

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Pil Uthaug Rasmussen; Ayco J. M. Tack; Martijn Bezemer; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aboveground-belowground interactions; arbuscular mycorrhiza; climate; dispersal; environmental drivers; fungi; genetic variation; nematodes; plant-herbivore interactions; soil communities; spatial patterns; Ecology and Evolution; ekologi och evolution;

    Abstract : Soil contains a wealth of diversity – bacteria, fungi, nematodes, arthropods and earthworms are just some of the many organisms found belowground. These organisms play an important role in shaping the soil environment and they strongly influence plant fitness, diversity and community composition. READ MORE
