  1. 1. Edible Fungal Production using Acetic Acid as Carbon and Energy Source

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi; Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Barbara Mae Alontaga; Anna Axebrink; [2020]
    Nyckelord :VFA; Volatile fatty acid; acetic acid; Fungi; Carbon source; Energy source;

    Sammanfattning : Volatile fatty acids (VFAs) have become attractive and gained high research interest due to its significance for the chemical industry and economical advantage. These acids can be produced by utilizing organic waste such as food waste as substrate through anaerobic digestion. LÄS MER

  2. 2. Skillnad i reaktivitet mellan olika cellulosaråvaror vid framställningen av cellulosaacetat

    Master-uppsats, Karlstads universitet

    Författare :Karl-Petter Bengtsson; [2020]
    Nyckelord :cellulosa cellulosaacetat utbyte;

    Sammanfattning : Detta arbetes syfte är att utveckla en metod som konsekvent kan hitta skillnader mellan olika cellulosaråvarors reaktivt vid syntetiseringen av cellulosaacetat med ättiksyraprocessen.  Detta undersöktes genom att förändra reaktionsparameterna mängd adderad svavelsyrakatalysator och temperatur.

  3. 3. Volatile fatty acid production and application as external carbon source for denitrification

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Cora Michelle Döhler; [2020]
    Nyckelord :VFAs; co-fermentation; primary sludge; food waste; denitrification; external carbon source; MBBR;

    Sammanfattning : By rethinking wastewater treatment plants (WWTPs) as resource recovery facilities, it is possible to de- velop the next generation of WWTPs. Moreover, it allows to accomplish environmental goals, such as reducing the CO2 footprint, and comply with increasing effluent standards regarding the concentration of nitrogen in a more sustainable way.

  4. 4. Polyhydroxyalkanoate Production from Municipal Waste Streams

    Master-uppsats, KTH/Resursåtervinning

    Författare :Elsa Eriksson; [2020]
    Nyckelord :Polyhydroxyalkanoate; volatile fatty acids; mixed culture; bioreactor; municipal waste streams; Polyhydroxialkanoat; flyktiga fettsyror; blandad kultur; bioreaktor; kommunalt avfall;

    Sammanfattning : Polyhydroxyalkanoates (PHAs) are a group of bioplastics, which are produced through microorganisms. They are accumulated in granules inside bacteria’s cell cytoplasm and serve as an energy reserve. LÄS MER

  5. 5. Development of a GC Method for the Quantification of Short Chain Carboxylic Acids in Aqueous Solution

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Anton Åkervall; [2020]
    Nyckelord :DAI-GC-FID; Direct Aqueous Injection; Gas Chromatography; Flame Ionization Detector; SCFA; Short Chain Fatty Acids; Formic Acid; Acetic Acid; Lactic Acid; EGR; Exhaust Gas Recirculation; CAC; Charged Air Cooler; FFD; Fractional Factorial Design;

    Sammanfattning : Petroleum powered vehicles emit volatile organic compounds (VOCs) through combustion that contributes to the pollution of the environment. A technique in the 1970s was developed to decrease these emissions, especially for nitrogen oxides (NOx) and sulphuric oxides (SOx) which is called exhaust gas recirculation (EGR). LÄS MER
