  1. 1. Biokinetic Characterization of Methane Oxidizing Microbiomes Co-metabolizing Trace Organic Chemicals

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Hugo Möller; [2024]
    Nyckelord :Methanotrophs; organic micropollutants; co-metabolism; biodegradation; applied microbiology; Earth and Environmental Sciences;

    Sammanfattning : The presence of organic micropollutants (OMPs) in wastewater effluents is concerning, as they pose a threat to human and aquatic health. Biodegradation via methane-oxidizing bacteria (MOB) is an attractive option, as the method is cheap and effective. MOB can co-metabolize a variety of substrates, there among organic micropollutants.

  3. 2. Investigation of an enzymatic cascade for the production of 5- hydroxymethylfurfurylamine

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Sajitha Chandrakumaran; [2023]
    Nyckelord :Biocatalysis; Silicibacter pomeroyi; transaminase; enzymatic cascade; Cadaverine; Biokatalys; Silicibacter pomeroyi; transaminas; Enzymatisk kaskad; Kadaverin;

    Sammanfattning : Biokatalys medför ett alternativt tillvägagångsätt för att kunna utforska och utveckla kemiskt syntetiserade vägar för produktionen av eftertraktade kemikalier, där hållbarhet och miljön tas till beaktan. I denna studie undersöktes potentialen av en enzymatisk kaskad för produktion av 5-hydroximetylfurfurylamin (HMFA). LÄS MER

  4. 3. Modeling PFAS Transport in Groundwater - Exploring current approaches and evaluating parameter importance

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

    Författare :Clara Eklund; [2023]
    Nyckelord :PFAS; Groundwater modeling; FEFLOW; Python; Machine learning; Technology and Engineering;

    Sammanfattning : PFAS contamination in drinking water is a current problem, and new regulations for drinking water limits were recently implemented in each member country of the EU in January this year. Understanding the spread of PFAS in groundwater is therefore important to prevent it from reaching drinking water sources. LÄS MER

  5. 4. Effects of recirculating water treatment sludge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sofia Mile; [2023]
    Nyckelord :Chemical Engineering; Water and Environmental Engineering; Water Treatment; Coagulation Flocculation; Sludge Recirculation; Technology and Engineering;

    Sammanfattning : Drinking water is crucial in our everyday life. As with many other processes, it is important to produce water of drinking quality in a sustainable manner. This can occur by e.g. LÄS MER

  7. 5. Risk assessment of non-intentionally added substances in polyester yarn made from recycled polyethylene terephthalate (PET)

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Kristina Arnqvist; [2023]
    Nyckelord :r-PET; polyester yarn; NIAS; risk assessment;

    Sammanfattning : Polyester is a synthetic material made from polyethylene terephthalate (PET), which is synthesised from fossil raw materials. Many clothing manufacturers are using polyester in their clothing, which, from an environmental perspective, creates a non-sustainable cycle. LÄS MER
