    University essay from Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Author : Erik Apelqvist; [2022]
    Keywords : Enzyme; Enzymatic characterization; Recombinant protein producaiton; Protien purification; E. coli; W. fucanilytica; Transformation; Overexpression; Seaweed; Ulvan; Polysaccharides; biotechnology; Biology and Life Sciences;

    Abstract : The aim of this thesis was to fully characterize the enzyme WFp-105, including bioinformatic analysis, structural modeling, full activity and stability characterization and product determination. As well as for the enzyme WFp-37; optimize protein production in regard to expression strains and cultivation temperature, analyzing the genomic context as well as performing an initial activity detection.

  3. 32. Emission of greenhouse gases from constructed wetlands : Nutrient status in relation to methane and nitrous oxide emission

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Christian Lundström; [2022]
    Keywords : Constructed wetland; greenhouse gas emission; nutrient status; ebullition; Anlagd våtmark; växthusgasutsläpp; näringsstatus; ebullition;

    Abstract : Agricultural land releases large amounts of nitrogen and phosphorus to water bodies which causes eutrophication. Creating wetlands on agricultural land is one way to prevent this major issue. However, constructed wetlands are a large emission source of greenhouse gases. READ MORE

  4. 33. Effects of vegetation and nutrients on methanotroph abundance and methane emissions from constructed wetlands

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

    Author : Klara Yngve; [2022]
    Keywords : Diffusive flux; Ebullition; Dissolved CH4; CH4 oxidation; Phosphorous;

    Abstract : Agriculture is the largest anthropogenic source of nitrogen and phosphorous (P) leakage to Swedish coastal seas, causing eutrophication which threatens marine ecosystems. Constructing wetlands is one way to improve nutrient retention in the modern agricultural landscape. However, constructed wetlands can emit substantial amounts of methane (CH4). READ MORE

  5. 34. Phosphorous Precipitation in Source Separated Greywater for Direct Environmental Release.

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Ashley Hall; [2022]
    Keywords : water; wastewater; source separation; greywater; phosphorous; precipitation; utfällning; Chemical Engineering; Technology and Engineering;

    Abstract : As our understanding of the impact humans have on the environment changes, so too do the mitigation strategies we employ to prevent it. One major source of anthropogenic pollution is wastewater effluent. READ MORE

  6. 35. Life Cycle Assessment of Urban Underground Oyster Mushroom Farming

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emile Lemaitre; [2022]
    Keywords : Life cycle assessment LCA ; Urban mushroom farming; Oyster mushrooms; Urban agriculture; Livscykelanalys LCA ; Urban svampodling; Ostronskivling; Stadsodling;

    Abstract : Global food production has been recognized as the single largest driver of environmental degradation and transgression of planetary boundaries. Providing healthy food sustainably to a growing, mostly urban population will require radical changes to the food system. READ MORE
