  2. 1. Interactions between Bacteria and Fungi on Aquatic Detritus – Causes and Consequences

    Author : Cecilia Mille-Lindblom; Lars Tranvik; Helmut Fischer; Eric Chauvet; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; bacteria; fungi; decomposition; antagonism; extracellular enzymes; competition; macrophytes; dissolved organic carbon DOC ; ergosterol; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Bacteria and fungi dominate the decomposition of aquatic plants, a major process in the carbon and nutrient cycling in many aquatic systems. Although phylogenetically distant, bacteria and fungi often live in close proximity with each other. Since these microorganisms also have similar ecological functions, interactions have developed between them. READ MORE

  4. 2. Chemical signals in interactions between Hylobius abietis and associated bacteria

    Author : Karolin Axelsson; Jenny Lindh; Anna-Karin Borg-Karlson; Gunaratna Kuttuva Rajarao; Benedicte Albrectsen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Pine weevil; Hylobius; Rahnella; Pseudomonas; bacteria; fungi; metabolites; 2-methoxyphenol; 2-phenylethanol; Kemi; Chemistry;

    Abstract : The pine weevil (Hylobius abietis L.) is one of the two topmost economically important insect pests in Swedish conifer forests. The damage increase in areas were the silvicultural practice is to use clear cuttings were the insects gather and breed. READ MORE

  5. 3. Phytoremediation of soil contaminated with petroleum hydrocarbons and trace elements

    Author : Charlotte Marchand; Hogland William; Hijri Mohamed; Bramryd Torleif; Linnéuniversitetet; []
    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

  6. 4. Pollution-Induced Community Tolerance (PICT) of Bacteria: Evaluation in Phenol- and Antibiotic Polluted Soil

    Author : Louise Aldén; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antibiotics; Bacteria; Community; Fungi; Leucine incorporation; Phenols; Soil; Pollution-Induced Community Tolerance PICT ;

    Abstract : The effects of organic pollutants on the soil microbial community were studied in this work. The main aim was to evaluate the use of pollution-induced community tolerance (PICT) in studying the effects of pollution. The leucine incorporation technique (indicating bacterial growth) was used to monitor changes in tolerance. READ MORE

  7. 5. Microbes Associated with Hylobius abietis : A Chemical and Behavioral Study

    Author : Muhammad Azeem; Anna Karin Borg-Karlson; Irena Valterová; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hylobius; Ewingella; Penicillium; Heterobasidion; Bacteria; Fungi; Bark; Forest waste; Metabolites; Styrene; Methyl salicylate.;

    Abstract : This thesis is based on three inter-related studies: the first part deals with the microbial consortium, the identification of microbes and their volatiles, the second part deals with the study of bio-chemical control methods of two conifer pests; the pine weevil Hylobius abietis (L.) and the root rot fungi Heterobasidion spp. READ MORE
