  1. 1. Solid-state fermentation of the microalgae Scenedesmus sp. for improved conservation and protein digestibility

    Master-uppsats, Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Författare :André Nordin Fürdös; [2023]
    Nyckelord :microalgae; scenedesmus; solid-state fermentation; lactic acid fermentation; algae; feed; ensiling; silage; protein digestibility; PDCAAS; alternative protein; plantarum; ninhydrin; conservation; biotechnology; Agriculture and Food Sciences;

    Sammanfattning : As part of a research grant aimed at producing chicken feed from the novel microalgae Scenedesmus sp., called the ReMAPP project, this thesis investigates opportunities to increase the conservation potential and protein digestibility utilizing solid-state lactic acid fermentation and commercial enzyme additives.

  3. 2. Pilotstudie - rötning med slamrecirkulering på Käppalaverket

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Joel Andersson; [2022]
    Nyckelord :mesophilic digestion; retention time; recirculation; sludge; lab-scale; organic loading; volatile fatty acids; pH; wastewater treatment; mesofil rötning; uppehållstid; recirkulering; slam; labbskala; organisk belastning; flyktiga fettsyror; pH; avloppsrening;

    Sammanfattning : Kommunala avloppsreningsverk renar avloppsvatten och avlägsnar näringsämnen innan vattnet släpps ut i den omgivande miljön. Under reningen avskiljs partiklar som bildar råslam. Genom att bryta ner råslammet anaerobt (syrefritt) via rötning kan användbara produkter, såsom biogas till bussar, erhållas. LÄS MER

  4. 3. Anaerobic Co-digestion of Digestate with Glycerol to enhance Biogas Production

    Master-uppsats, Linköpings universitet/Institutionen för tema

    Författare :Prince Kwarteng Adiyia; [2021]
    Nyckelord :Biogas; Anaerobic Digestion; Digestate; Glycerol;

    Sammanfattning : The Brazilian sugarcane and ethanol industries produce lot of waste which has potential for energy production. Anaerobic digestion (AD) can be effectively utilized for producing biogas from these wastes. LÄS MER

  5. 4. Investigating the methane producing pathway in lab-scale biogas reactors subjected to sequential increase of ammonium and daily acetate-pulsing

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

    Författare :Sofia Moberg; [2020]
    Nyckelord :Syntrophic acetate oxidation; syntrophic acetate oxidizing bacteria; Wood-Ljungdahl pathway;

    Sammanfattning : Syntrophic acetate oxidizing bacteria convert acetate into hydrogen and carbon dioxide and through the mutualistic syntrophic partnership with methanogens the products are further converted to methane in biogas processes operating at high ammonia concentrations. There is very little known about SAOBs, only five have been characterized and had their genome analyzed. LÄS MER

  7. 5. Effect of biofilm thickness and carrier type on the performance of anaerobic moving bed biofilm reactors (AnMBBRs)

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Astrid Hermansson; [2020]
    Nyckelord :Anaerobic; wastewater treatment; AnMBBR; MBBR; biofilm thickness; carrier; organic removal; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Sammanfattning : The anaerobic moving bed biofilm reactor (AnMBBR) is a wastewater treatment process that has shown effective for the treatment of industrial wastewaters. As the AnMBBR is a biofilm process, nutrients, products, etc. must be transported through the biofilm. The thickness of the biofilm may, therefore, impact the process. LÄS MER
