  1. 21. Fodder yeast and biogas production: A fruitful symbiosis? : optimization of a single-cell protein process and examination of its impact on biogas output

    University essay from SLU/Dept. of Microbiology

    Author : Jonas Ohlsson; [2016]
    Keywords : fodder yeast; biogas; nutrient recycling; Wickerhamomyces anomalus; Pichia kudriavzevii; Blastobotrys adeninivorans;

    Abstract : Due to a growing world population and strained wild fish stocks, aquaculture is expected to provide a large part of the increased global demand for animal protein, as the majority of wild fish stocks are already being fished at or above their sustainable capacity. However, fish feed often contains a significant amount of fish meal, produced from wild-caught fish. READ MORE

  3. 22. Assessment of changes in algal biomass accrual and leaf decomposition along a gradient of increasing agricultural dis-turbance

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Maisam Ali; [2015]
    Keywords : leaf decomposition; algal biomass accrual; stream biodiversity;

    Abstract : 1. Anthropogenic activities may impact stream ecosystems by distorting the energetic linkages between the aquatic and adjacent terrestrial habitats, or by modifying the aquatic environment directly. READ MORE

  4. 23. Logging impacts on catchment biogeochemistry: A review : with emphasis on northern boreal ecosystems

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Daniel Karlsson; [2014]
    Keywords : Boreal forest; clear-cutting; nutrients; lake ecosystems; physical parameters;

    Abstract : The impacts of current forest management methods on surface water quality, especially in northern parts of Sweden, are largely unexplored. In this review reports linked to logging impacts on catchment biogeochemistry, (with special emphasis on boreal ecosystems) has been assessed. READ MORE

  5. 24. Influence of the metabolic inhibitor sesamin on the fatty acid profile of the oleaginous yeast Rhodotorula glutinis

    University essay from SLU/Dept. of Microbiology

    Author : Louise Holmgren; [2014]
    Keywords : Rhodotorula glutinis; sesamin; long chain polyunsaturated fatty acids; altering the fatty acid profile;

    Abstract : Rhodotorula glutinis has been one of the top candidates among oleaginous yeast for several microbial lipid applications, such as biofuel production. In this project the effect of sesamin on the fatty acid profile was investigated by culturing R. READ MORE

  6. 25. Microbial communities in a boreal forest podzol profile and responses to the presence of Pinus sylvestris seedling roots

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Johanna Jernberg; [2013]
    Keywords : Archaea; Bacteria; Boreal forest; DGGE; Fungi;

    Abstract : The boreal biome consists of coniferous forests that cover much of the northern hemisphere, and constitute an important natural resource for the forest industry, but has also gained attention in the light of global warming in acting as potential sinks of atmospheric carbon dioxide. Both forest production and carbon sequestration are closely connected to the activities of soil microorganisms, which play major roles in nutrient cycling and decomposition of plant biomass. READ MORE
