1. 21. Microorganisms in indoor environments. A search for health-related measurements

   Författare :Loay Wady; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; bacteriology; virology; Microbiology; schools; microbial markers; MVOCs; building materials; dust; GC MSMS; SPME;

   Sammanfattning : Microorganisms are ubiquitous in indoor air and epidemiological data suggest that inhalation of microbes and/or their products adhered on air–borne dust particles can impair well–being and health. In the present thesis microbial volatile organic compounds (MVOCs) and cellular markers were studied by gas chromatography–mass spectrometry (GC/MS). LÄS MER

3. 22. Determination and control of some pollutants in indoor environments

   Författare :Pawel Markowicz; Avdelningen för medicinsk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; indoor pollutants; dampness; purification; tobacco smoke;

   Sammanfattning : Unsatisfactory indoor air quality (IAQ) may result from polluting emissions that are spread from building materials such as volatile organic compounds (VOCs) and/or microbial components or from various kinds of human activity such as smoking. Different methods are available to limit the exposure to unwanted pollutants and improve human wellbeing and health. LÄS MER

4. 23. Trichoderma viride alamethicin and plant cells - Action, response and resistance

   Författare :Mari Aidemark; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; Nicotiana tabacum; cell cultures; alamethicin; cell permeabilisation; resistance; callose; BY-2;

   Sammanfattning : Alamethicin is a membrane active peptide secreted from the soil-living fungus Trichoderma viride. When coexisting with T. Viride, plant roots are exposed to alamethicin, which has the ability to elicit formation of volatile compounds involved in pathogen defence. LÄS MER

5. 24. Enhanced Biological Phosphorus Removal - Carbon Sources, Nitrate as Electron Acceptor, and Characterisation of the Sludge Community

   Författare :Magnus Christensson; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; nitrate; carbon source; PAO; polyphosphate accumulating organisms; enhanced biological phosphorus removal; EBPR; characterisation; Biotechnology; Bioteknik;

   Sammanfattning : Enhanced biological phosphorus removal (EBPR) was studied in laboratory scale experiments as well as in a full scale EBPR process. The studies were focused on carbon source transformations, the use of nitrate as an electron acceptor and characterisation of the microflora. LÄS MER

7. 25. Valorization of herring filleting co-products to silage - Control of protein hydrolysis and lipid oxidation during ensilaging and possibilities for separating herring silage into multiple products

   Författare :Mursalin Sajib; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; separation; silage; pilot-scale; lipid oxidation; Herring Clupea harengus ; protein hydrolysis; ensilaging; antioxidants; fish oil; valorization; by-products;

   Sammanfattning : Industrial processing of herring ( Clupea harengus ) into convenience products such as fillets generates around 60% co-products being rich in both protein and n-3 polyunsaturated fatty acids (PUFAs). A promising cost-efficient strategy to valorize these raw materials into food and/or feed ingredients would be to apply ensilaging, i.e. LÄS MER
