1. Azoles and Contaminants in Treated Effluents Interact with CYP1 and CYP19 in Fish
Sammanfattning : Numerous contaminants are present in mixtures in the aquatic environment. Among these are the azoles, a group of chemicals that includes both pharmaceuticals and pesticides. Azole fungicides are designed to inhibit lanosterol 14-demethylase (cytochrome P450 (CYP) 51), while other azoles are intended to inhibit aromatase (CYP19), i.e. LÄS MER
2. Structure and function of microbial communities in constructed wetlands - influence of environmental parameters and pesticides on denitrifying bacteria
Sammanfattning : This thesis addresses the interactions and relationships between natural aquatic bacterial communities, environmental parameters, anthropogenic chemicals and the denitrification pathway in the habitat of agricultural constructed wetlands. The main aim was to gain fundamental knowledge of the drivers behind the processes of the denitrification (i.e. LÄS MER
3. Surface Sampling and Automated Liquid Membrane Extraction of Fungicides
Sammanfattning : A number of approaches for fungicide determination are presented. A surface sampling technique is utilised for the determination of fungicide foliar residues on greenhouse surfaces, mainly leaves. The procedure is based on solvation of the fungicides on the leaf surface with ethanol and HPLC analysis. LÄS MER
4. Boosting potato defence against late blight : a study from field to molecule
Sammanfattning : For more than one century efforts has been made to obtain potato (Solanum tuberosum) cultivars resistant to late blight. However, introduced resistance has repeatedly been overcome by Phytophthora infestans (Mont) de Bary. LÄS MER
5. Insights into population structure and epidemiology of Phytophthora infestans from Nicaragua
Sammanfattning : Late blight caused by Phytophthora infestans (Mont) de Bary is a constraint to both potato and tomato crops in the northern highlands of Nicaragua. This thesis describes studies on population structure and epidemiology of P. infestans from Nicaragua. The genotypic and phenotypic variation in isolates of P. LÄS MER
