1. 21. Biogeochemical Processes in Denitrifying Woodchip Bioreactors and their Application in the Mining Industry

   Författare :Albin Nordström; Roger Herbert; Fritjof Fagerlund; Gunno Renman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water treatment; mine drainage; nitrate; nitrous oxide; DNRA; fermentation; syntrophy; temperature; kväverening; gruvvatten; nitrat; lustgas; DNRA; fermentation; syntrofi; temperatur; Hydrology; Hydrologi;

   Sammanfattning : This thesis evaluates passive denitrifying woodchip bioreactors (DWBs) for the removal of nitrate (NO3-) in neutral pH mine drainage, where water is passed through a carbon-rich porous matrix (e.g. woodchips) for the reduction of NO3- to nitrogen gas. LÄS MER

3. 22. Biomedical Applications of Bacterial Cellulose Fermentation, Morphology and Surface Properties

   Författare :Aase Katarina Bodin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocompatibility; xyloglucan epitopes; mechanical properties; cell adhesion; tubular fermentation; morphology; Bacterial cellulose; surface properties; meniscus mold; crystal formation.; ozonation; adsorption;

   Sammanfattning : Because average life expectancy has increased and peoples lifestyles have changed, degenerative diseases have become a critical issue. The demand for biomedical materials to replace or improve major body systems (skeletal, circulatory and nervous, etc.) will increase as people strive to maintain good quality of life. LÄS MER

4. 23. Dietary Fibre in Fermented Oats and Barley

   Författare :Adele Lambo; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Näringslära; Nutrition; short-chain fatty acids ; exopolysaccharides; fermentation; barley; oats; Dietary fibre polysaccharides; cholesterol ;

   Sammanfattning : The physiological characteristics of native and bacterial exopolysaccharides (EPS) in oats and barley-based fermented products were studied in relation to the physico-chemical properties. Article I presents a parallel-randomized double blind clinical trial using a dairy-based product (control), an oat-based product (fermented with V2, which is a mixture (1:1) of Lactobacillus delbrueckii subsp.

5. 24. Impact of Cultivation Parameters on Cell Physiology of Limosilactobacillus reuteri

   Författare :Nikhil Seshagiri Rao; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; probiotics; L. reuteri; oxygen; fermentation; heterogeneity; morphology; flow cytometery; freeze-drying; stress tolerance; Online flow cytometry; k-means clustering; fatty acids; defined minimal media; pre-formulation hold time;

   Sammanfattning : Optimisation of cultivation conditions in the industrial production of probiotics is crucial to reach a high-quality product with high probiotic functionality. The production process includes a fermentation step to produce biomass, accompanied by centrifugation to concentrate the cells. LÄS MER

7. 25. Nutritional Assessment in a Rural Area of Bolivia. A Study of Zinc and Iron Deficiencies and Bioavailability

   Författare :Claudia Lazarte; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; zinc; iron; deficiencies; bioavailability; fermentation; developing countries; plant-based diets;

   Sammanfattning : While originally, protein-energy deficiency was considered the main factor of malnutrition, it is now understood that micronutrient deficiencies play a fundamental role in a variety of health and disease outcomes. Zinc and iron deficiencies are still highly prevalent in low-income countries, whereas insufficient intakes and diets with low mineral absorption are the major causes. LÄS MER
