1. Nutrient balance and salinity stress in arbuscular mycorrhizal fungi
Sammanfattning : Earth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. LÄS MER
2. The late blight pathogen, Phytophthora infestans : interaction with the potato plant and inoculum sources
Sammanfattning : The oomycete, Phytophthora infestans, is one of the most important plant pathogens worldwide. This thesis focuses on the late blight pathogen and its host, potato (Solanum tuberosum), and the interaction between these two organisms. Resistance to P. LÄS MER
3. Evaluation of process parameters and treatments of different raw materials for biogas production
Sammanfattning : The anaerobic digestion process results in the production of biogas from a large diversity of organic residues, which can be used as an alternate source of energy generation and for waste management. However, the biogas production technology is not exploited efficiently due to the characteristics of raw materials, poor methane yields, process instability, limited raw materials and lack of knowledge about the process.

4. Monitoring important soil-borne plant pathogens in Swedish crop production using real-time PCR
Sammanfattning : The global demand for food will increase considerably in the nearest future and among the major constraints to agricultural productivity are biotic stresses caused by microorganisms. In this thesis, the causal agents of four of the most important soil-borne diseases threatening the Swedish production of oilseed rape, sugar beets and red clover were selected as targets for developing diagnostic assays using real-time PCR.

5. Factors that Influence the Biochemical Methane Potential (BMP) Test : Steps towards the Standardisation of BMP Test
Sammanfattning : Anaerobic digestion (AD) has gained increasing attention nowadays as an approach for both waste treatment and renewable energy generation. Currently, many different types of materials can be used as feedstock for biogas production via AD process, but their biodegradability (based on methane yield, BDCH4) and potential to produce biogas might vary significantly, and these properties are key parameters that should be taken into consideration for economy, design and operation of a full-scale biogas plant during the selection of potential feedstock.
