    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Erika Lundgren; [2014]
    Keywords : Solar water pasteurisation; surface water; semi-permanent device; solar radiation; Bangladesh.;

    Abstract : In order to improve the water situation in rural areas of Bangladesh, a research group at the University of Dhaka has been developing low cost domestic methods to remove pathogens from surface water through pasteurisation using free solar energy. Pasteurisation is a process in which water is heated to approximately 60 °C and maintained for about 30 minutes to destroy pathogens. READ MORE

  3. 17. Isolation of antibiotic producing microorganisms by screening for antibiotic resistance

    University essay from SLU/Dept. of Microbiology

    Author : Emma Nordenfjäll; [2014]
    Keywords : antibiotics; secondary metabolites; antibiotic resistance; isolation methods; rare-actinomycetes; unexplored ecological niches; diterpene synthases; non-ribosomal peptide synthases; type I polyketide synthases; type II polyketide synthases;

    Abstract : The worldwide use of antibiotics has rapidly increased since the discovery of the secondary metabolite penicillin made by Alexander Fleming in 1928. Since then, thousands of useful secondary metabolites of microbial origin have been discovered. About 80 % of these substances originate from Actinomycetes and in particularly Streptomyces species.

  5. 19. Nitrous oxide and methane emissions from a long-term fertilizer experiment

    University essay from SLU/Dept. of Microbiology

    Author : Martin Palmqvist; [2012]
    Keywords : Nitrous oxide; Methane; Fertilizer;

    Abstract : Because of the increasing concentration of methane (CH4) and nitrous oxide (N2O) in the atmosphere, there is an increasing concern about the emissions of these two gases from agricultural land. Both CH4 and N2O are major contributors to the greenhouse effect and agricultural lands constitute a large contributor of the anthropogenic load of these gases. READ MORE

  6. 20. A small growth study of Aspergillus section Flavi, and potentially aflatoxigenic fungi and aflatoxin occurrence in Brazil nuts from local markets in Manaus, Brazil
