  1. 1. Fungal degradation patterns and toxicity of furfurylated wood

    Författare :Annica Pilgård; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Daphtox; Quantitative real-time PCR; Furfurylation; Microtox; Basidiomycota; Acetylation; Wood modification.; Daphnia magna; Thermal modification; Trametes versicolor; Decay; Vibrio fischeri;

    Sammanfattning : The demand for timber products is increasing with global population and affluence. Concerns regarding conventionally used toxic wood preservatives and the deforestation of tropical forests have become more prominent both socially and politically. Wood based products are generally recognised as an environmentally favourable raw material. LÄS MER

  2. 2. Fungal taxonomy and systematics in the digital era, with an outlook on the cantharelloid clade (Basidiomycota)

    Författare :R. Henrik Nilsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cantharelloid clade; ectomycorrhiza; Agaricomycetes; phyloinformatics; barcoding;

    Sammanfattning : Fungi form a large and ubiquitous group of organisms where species identification and delimitation on morphological grounds often fall short. DNA sequences have proved an invaluable information source for these pursuits and are now routinely used in most mycological laboratories. LÄS MER

  3. 3. Understanding virulence of Heterobasidion annosum s.l., a root rot pathogen of conifers

    Författare :Yang Hu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Heterobasidion annosum sensu lato (s.l.) species are destructive pathogens causing root and butt rot in conifers. The species complex consists of five species: H. LÄS MER

  4. 4. Microbial strategies for deconstruction of bark components

    Författare :Amanda Sörensen Ristinmaa; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; extractives; fungi; microbial communities; polysaccharides; Bark; proteomics; enzymes; bacteria; yeast;

    Sammanfattning : Bark is the outermost part of a tree, and it is a protective layer against external threats such as microorganisms and environmental stressors. Bark consists of various polymers including lignin, cellulose, hemicellulose, and it also contains a large fraction of compounds known as extractives. LÄS MER

  5. 5. Microbial Metagenomics : A Tale of the Dead and the Living

    Författare :Katarzyna Zaremba-Niedźwiedzka; Siv G.E. Andersson; Jeroen Raes; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; single-cell genomics; single cell; fossil metagenome; freshwater metagenome; LD12;

    Sammanfattning : It is a microbial world we live in: microbes outnumber other organisms by several orders of magnitude, and they have great importance for the environment. However, environmental microbes are notoriously difficult to grow in the laboratory, and using culture independent techniques is necessary to expand our view. LÄS MER
