  2. 16. Analysis of PAHs and their transformations products in contaminated soil and remedial processes

    Author : Staffan Lundstedt; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; polycyclic aromatic hydrocarbons; PAHs; degredation; transformation; formation; accumulation; oxidation products; metabolites; oxogenated polycyclic aromatic hydrocarbons; oxy-PAHs; soil; gasworks; remediation; bioremediation; bioslurry; wood-rotting fungi; Fenton´s reagent; avaliability; bioavaliability; chemical analysis; extraction; pressurized liquid extraction; PLE; accelerated solvent extraction; ASE; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

    Abstract : Soil that is heavily contaminated with polycyclic aromatic hydrocarbons (PAHs) is often found at the sites of former gasworks and wood-impregnation plants. Since PAHs are toxic these sites represent a hazard to human health and the environment, and therefore they need to be treated, preferably by a method that destroys the contaminants, and thus eliminates the problem permanently.

  4. 17. Heart rot of spruce and alder in forests of Latvia : impact and possibilities for silvicultural control

    Author : Natalija Arhipova; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Heart rot causes great decrease in timber quality throughout the world. In the conifer forests of Northern Hemisphere the most significant losses are caused by fungi from the Heterobasidion annosum species complex. READ MORE

  5. 18. The external mycorrhizal mycelium - growth and interactions with saprophytic microorganisms

    Author : Pål Axel Olsson; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacteriology; Microbiology; Fatty acids; Mycorrhiza; Bacteria; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The interactions between external mycorrhizal mycelia and saprophytic microorganisms were studied in experiments with growth chambers specially designed to enable the mycelia to develop in root-free soil compartments. The growth of the mycorrhizal mycelia was estimated by use of biochemical signature compounds. READ MORE

  6. 19. Functional aspects of cellobiose dehydrogenase Applications for biosensor development

    Author : Leonard Stoica; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elektrokemi; Electrochemistry; Analytisk kemi; Analytical chemistry; bioelectrochemistry; direct electron transfer; lactose biosensor;

    Abstract : Electrochemcial investigations were conducted for elucidating and understanding the relation between the various electron transfer processes occurring in cellobiose dehydrogenase (CDH) bound to an electrode surface. Substrate inhibition caused by cellobiose was proven to act in competition with the electron transfer to a two-electron acceptor and under a partial inhibition mechanism for the internal electron transfer process.

  7. 20. Adsorption, desorption, and redox reactions at iron oxide nanoparticle surfaces

    Author : Lelde Krumina; MEMEG; []
    Keywords : Ferrihydrite; Goethite; Secondary metabolites; Reductive dissolution; Catalytic oxidation; hydroxyl radicals; Fenton reaction; SOM decomposition;

    Abstract : Iron oxide nanoparticles are involved in several important biogeochemical processes. The interfaces between aqueous solutions and iron oxide nanoparticle surfaces are found everywhere in nature, and the chemical and microbial processes occurring at these complex interfaces control e.g. nutrient and contaminant availability and transport.
