    Sammanfattning : An introduction to bacterial polysaccharides and the methods for structural determination are described in the first two parts of the thesis.In a structural elucidation of bacterial polysaccharides NMR experiments are important as is component analysis. A short description of immunochemical methods such as enzyme immunoassays is included. LÄS MER

    Sammanfattning : Polysaccharides represent an important resource for a variety of products, from food via fuel supply to functional materials of every kind. Here they are, due to their natural diversity found in many special applications, e.g. in the biomedical sector. LÄS MER

  7. 10. 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
