  1. 6. Physiology of Caulobacter crescentus grown on different carbon sources

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sara Lind Jónsdóttir Glaser; [2016]
    Nyckelord :aerobic cultivation; physical characterization; lignocellulosic biomass; xylose degradation; Weimberg; bioreactors; enzyme assays; chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : Freshwater, obligate aerobic, Gram-negative bacterium Caulobacter crescentus strain CB2 is able to metabolise various types of carbon sources. In this degree project, growth characterization of C.crescentus was made on different substrates including glucose, xylose, and mannose using shake-flask cultivations and bioreactor experiments.

  3. 7. Biogaspotential vid samrötningav mikroalger och blandslam från Västerås kommunala reningsverk

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Tova Forkman; [2014]
    Nyckelord :biogas; biogas potential; methane production; co-digestion; microalgae; mesophilic digestion; biogas; biogaspotential; metangasproduktion; samrötning; mikroalger; mesofil rötning;

    Sammanfattning : Because of the increasing trends in energy consumption and increased environmental awareness, greater focus has been placed on improvement and development of renewable energy sources. An already proven and accepted method is biogas production from anaerobic digestion at municipal wastewater treatment plants. LÄS MER

  4. 8. Aquaculture effluents as fertilizer in hydroponic cultivation : a case study comparing nutritional and microbiological properties

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Johan Lund; [2014]
    Nyckelord :Organic hydroponic; Aquaponic; Aquaculture; Plant nutrition; Microbial horticulture;

    Sammanfattning : This paper evaluates the prospects for utilizing aquaculture effluents as a nutrient source in organic hydroponic, as is the case in aquaponics. The development of organic hydroponics is dependent on replacing synthetic fertilizers with organically derived nutrients, such as those found in aquaculture effluents. LÄS MER

  5. 9. β-galaktosidas assay för studie av promotorregion i kloritdismutas från Ideonella dechloratans

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Emelie Johansson; [2014]
    Nyckelord :Biokemi; kemi;

    Sammanfattning : Oxochlorates are anions with a partially naturally occurrence in nature but are also spread by human activities, including the paper industry. These compounds are harmful to both nature and humans, which makes it necessary to find a good way for their degradation. LÄS MER

  7. 10. A sample preparation method for microbiological analysis of seeds

    Master-uppsats, SLU/Dept. of Microbiology

    Författare :John Bylund; [2013]
    Nyckelord :alfalfa; Escherichia coli; fenugreek; mung bean; Salmonella;

    Sammanfattning : There have been several outbreaks of food poisoning linked to the consumption of raw sprouts. The two most common pathogens associated with sprout consumption are Salmo-nella spp and verocyto-toxin producing Escherichia coli. During sprouting the warm, humid and nutrient rich conditions are ideal for bacterial growth. LÄS MER
