  1. 11. Enzymatic Pretreatment of Lignocellulose Rich Waste for Improved Biogas Production

    Master-uppsats, Tema vatten i natur och samhälle; Filosofiska fakulteten

    Författare :Carin Kvillborn; [2013]
    Nyckelord :Biogas; anaerobic digestion; lignin; laccase; versatile peroxidase; NMMO; Biogas; anaerob nedbrytning; lignin; laccase; versatile peroxidas; NMMO;

    Sammanfattning : The present study aimed to investigate the methane yield from anaerobic digestion of a lignocellulosic substrate subjected to different pretreatments. The lignocellulosic forest residues materials were milled and then pretreated with the organic solvent NMMO (N-Methylmorpholine N-oxide) and/or the lignolytic enzymes laccase and versatile peroxidase at a dosage of 60 U g-1 total solids (TS) substrate.

  3. 12. Optimization and validation of a triplex real-time PCR assay for thermotolerant Campylobacter species associated with foodborne disease

    Master-uppsats, SLU/Dept. of Microbiology

    Författare :Maria Karlsson; [2013]
    Nyckelord :thermotolerant Campylobacter; multiplex real-time PCR; 16S rRNA; hipO; cadF;

    Sammanfattning : The genus Campylobacter is globally recognised as the leading bacterial cause of human foodborne gastroenteritis. Every year around 8000 Swedes are infected by Campylobacter. Most people are infected by thermotolerant Campylobacter species, commonly C. jejuni and C. LÄS MER

  4. 13. Environmental fate of pesticides used as seed dressing : transport behaviour and occurrence in watercourses

    L3-uppsats, SLU/Dept. of Soil Sciences

    Författare :Åsa Kuhlau; [2008]
    Nyckelord :seed dressing; pesticide; leaching; water; environment; monitoring;

    Sammanfattning : Residues of chemical substances contained in pesticides (plant protection products) have been found in streams in four agricultural areas in Sweden despite no reported direct use. This report investigated whether these residues originated from seed dressing preparations used in the areas or some other source. LÄS MER

  5. 14. The effect of urban runoff on the water quality of the Sweetbriar Brook, Ampthill, UK

    L3-uppsats, SLU/Dept. of Soil Sciences

    Författare :Anna Krafft; [2006]
    Nyckelord :runoff; water quality; catchment; thermotolerant coliform bacteria; nutrients; rain; first flush; Sustainable Urban Drainage System SUDS ; sediment;

    Sammanfattning : The Sweetbriar Brook, a small watercourse in Ampthill, Bedfordshire, in a mainly residential catchment, was studied. The scope was to characterise the water quality during low flow conditions and storms, by chemical analyses of dissolved oxygen, turbidity, metals, nutrients, oil and thermotolerant coliform bacteria, among others.
