  2. 11. Impact of Brassicaceae cover crops on pea root rot (Aphanomyces euteiches) in subsequent peas

    Author : Shakhawat Hossain; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The soil-borne pathogen Aphanomyces euteiches Drechs is among the greatest threats to pea production world-wide. This pathogen can persist in soil for many years without a host plant and is very difficult to control due to its long-lived oospores and to environmental restrictions on fungicide application.

  4. 12. Ecology and genomics of microorganisms reducing the greenhouse gas N₂O : examples from the rhizosphere

    Author : Daniel Graf; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Nitrous oxide (N₂O) is a potent greenhouse gas and the major ozone depleting substance in the stratosphere. One major source of N₂O is incomplete denitrification, whereas the only known tropospheric sink of N₂O is the microbial enzyme nitrous oxide reductase. READ MORE

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

    Author : Karin Tornberg; Biologiska institutionen; []
    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

  6. 14. Physiology and Genetics of Acidithiobacillus species : Applications for Biomining

    Author : Olena Rzhepishevska; Mark Dopson; Wolfgang Sand; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Mikrobiologi;

    Abstract : Bacteria from the genus Acidithiobacillus are often associated with biominingand acid mine drainage. Biomining utilises acidophilic, sulphur and ironoxidising microorganisms for recovery of metals from sulphidic low grade oresand concentrates. READ MORE

  7. 15. Encounters at the microscale: Unraveling soil microbial interactions with nanoplastics

    Author : P. Micaela Mafla-Endara; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microfluidic devices; Nanoplastics; Soil microorganisms; Toxicity;

    Abstract : Nanoplastics (NPs) originated from plastic residues can interact with soil microorganisms with potential negative effects to their functions. Therefore, I aimed to investigate soil microbial population dynamics when exposed to different NP polymers and concentrations. READ MORE
