  2. 2. In vitro and in vivo oxidation of diastereomers of lignin models of arylgylcerol b-aryl ether type and heterologous expression of laccase

    University dissertation from Umeå : Umeå universitet

    Author : Christina Bohlin; Karlstads universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; Kemi; Chemistry;

    Abstract : Enzymic and non-enzymic oxidation of lignin models of the arylglycerol β-aryl ether type was investigated in experiments aimed at providing a better understanding of the initial phase of biological lignin degradation. Product profiles and diasteromer selectivity were determined to gain knowledge of the properties of the oxidants and pave the way for evaluation of the presence of the oxidants in ligninolytic fungal cultures.

  3. 3. Mycotoxins in indoor environments. Determination using mass spectrometry

    University dissertation from Lund University

    Author : Erica Bloom; Lunds universitet.; Lund University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas chromatography; Mass spectrometry; Mycotoxin; Indoor Air; Ergosterol.; Mold; High pressure liquid chromatography; Dust; Building materials;

    Abstract : Dampness in indoor environments may cause various health problems. The specific causative agent(s) are unknown but may originate from degradation processes in damp materials, microbial growth, or a combination of these phenomena. The health impact of dampness in buildings is a politically, legally, and economically important question. READ MORE

  4. 4. Fungal DNA, Mould, Dampness and Allergens in Schools and Day Care Centers and Respiratory Health

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Guihong Cai; Uppsala universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Day care centers; Quantitative PCR; Fungal DNA; Allergens; Indoor environment; Building dampness; Bacteria; Mycotoxins; Respiratory symptoms; Asthma; School environment; Viable moulds; School children; Occupational and Environmental Medicine; Arbets- och miljömedicin;

    Abstract : Day care centers and schools are important environments for children, but few epidemiological studies exist from these environments. Mould, dampness, fungal DNA and allergens levels in these environments and respiratory health effects in school children were investigated in this thesis. READ MORE

  5. 5. Industrial applications and properties of oxalate-degrading enzymes

    University dissertation from Karlstad : Karlstad University

    Author : Sandra Winestrand; Karlstads universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oxalic acid; oxalate oxidase; oxalate decarboxylase; calcium oxalate; scaling; active packaging; Kemi; Chemistry;

    Abstract : Oxalate-degrading enzymes were investigated with focus on potential applications in the pulp and paper industry and in active packaging. Changes introduced to make the pulp and paper industry more environmentally friendly, such as recirculation of process-water streams and elementary chlorine free bleaching of pulp, have led to increasing problems with precipitation of calcium oxalate.
