  1. 1. Mikrobiologisk kvalitet på is från ismaskiner och vatten från automater : en kontroll av verksamheters hygienrutiner

    University essay from SLU/Department of Molecular Sciences

    Author : Marta Marciniak; [2022]
    Keywords : provtagning; mikrobiologi; rengöring; vatten; vattenautomat; barpistol;

    Abstract : Mikrobiologiska föroreningar av dricksvatten är globalt den allvarligaste risken för människors hälsa (World Health Organisation WHO, 2004). Den här studien genomfördes som en del av ett tillsynsrelaterat provtagningsprojekt om mikrobiologisk kvalitet på is från ismaskiner och vatten från barpistoler/vattenautomater hos livsmedelsverksamheter i Alingsås kommun.

  3. 2. Cradle-to-Gate LCA of Water Treatment Alternatives : A case study performed for Norrvatten’s future waterwork expansion

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Siddharth Selvarajan; [2021]
    Keywords : Life cycle assessment; Water purification method; Potable water production; Microbiological barrier; Activated carbon; Sludge separation; Livscykelbedömning; Vattenreningsmetod; Produktion av dricksvatten; Mikrobiologisk barriär; Aktivt kol; Slamavskiljnin;

    Abstract : Norrvatten is a municipal association which owns a water treatment plant capable of supplying good quality drinking water to the consumers in the associated neighbouring municipalities. After preliminary investigations for the future year of 2050, there were estimates which suggest a potential water quality degradation in the lake which supplies the raw water for treatment due to uncertain future climatic conditions and other forms of pollutions from the surrounding.

  4. 3. Exploring Flow Cytometry for Monitoring of Microbial Water Quality During Maintenance of Drinking Water Pipes

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Måns Zamore; [2021]
    Keywords : flow cytometry; microbiology; drinking water; applied microbiology; Biology and Life Sciences;

    Abstract : Faster methods of analysing microbial drinking water quality after pipe breaks or new pipe installations would have beneficial implications. This thesis investigates the use of flow cytometry and cultivation-based techniques in connection to maintenance works, and how flow cytometry can aid in the decision-making around putting drinking water pipes in operation.

  5. 4. Traits of peat- and upland-derived stream dissolved organic carbon in the permafrost region around Abisko, northern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nora Kainz; [2021]
    Keywords : physical geography; ecosystem analysis; permafrost degradation; DOC; DOC concentration; stable isotope carbon signature; DOC quality; DOC degradation; Atmospheric Sciences and Biogeochemical Cycles; Earth and Environmental Sciences;

    Abstract : Climate change-induced thawing of permafrost mobilizes previously frozen carbon of high potential reactivity, thereby, fuelling microbiological production of greenhouse gases. For this work, an analysis of the quantity, quality, and bioreactivity of DOC in streams from the Stordalen discontinuous permafrost catchment was carried out with stream water samples during the relatively warm summer of 2018.

  6. 5. Quality of fermented dairy products beyond best before date

    University essay from SLU/Department of Molecular Sciences

    Author : Therese Holmsten; [2020]
    Keywords : yoghurt; sour milk; date labelling; rheology; microbiological plating method; Pivot Profile;

    Abstract : Date labelling is one factor influencing food waste in consumer households and evaluation of optimum shelf life is a tool food industry can use to contribute to di-minished food waste. This explorative pilot study aimed to investigate how quality of sour milk and yogurt changed beyond best before date. READ MORE
