1. 1. Effect of substrate types on fermentation of mixed cultures to produce volatile fatty acids

   Master-uppsats, KTH/Industriell bioteknologi

   Författare :Jayant Sehgal; [2022]
   Nyckelord :Mixed culture fermentation; Volatile fatty acids; Chemical oxygen demand; pH; starch; oil; gelatin; substrates; VFA production; Blandkulturjäsning; Flyktiga fettsyror; Kemiskt syrebehov; pH; stärkelse; olja; gelatin; substrat; VFA-produktion;

   Sammanfattning : Innovativa teknologier, produkter och processer krävs på grund av marknadens ökande behov av bioprodukter med låga koldioxidavtryck. Idén att producera flyktiga fettsyror via biologiska processer, främst genom anaerob fermentering med blandkulturer, har återupplivats på grund av den omfattande exploateringen av oljeresurser.

3. 2. Enhancement of hydrolysis from co-fermentation of food waste and primary sludge

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

   Författare :Johnny Hagelin; [2021]
   Nyckelord :Environmental engineering; Bioaugmentation; Fermentation; Hydrolysis; Resource recovery;

   Sammanfattning : Research about resource recovery from complex waste streams is getting an increased scientific attention since valuable resources can be produced by sustainable biological means. In anaerobic degradation processes, resources such as volatile fatty acids (VFAs) and biogas are highly coveted. LÄS MER

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

   M1-uppsats, 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

5. 4. Production of volatile fatty acids from anaerobic digestion using food waste, sludge and cow manure

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

   Författare :Zahraa Alshwan; Simon Hultman; [2019]
   Nyckelord :VFAs; anaerobic digestion; food waste; sludge; cow manure;

   Sammanfattning : Volatile fatty acids (VFAs) are important building blocks for the chemical industry. These acids can be produced through environmentally friendly processes from a variety of wastes, such as food waste, sludge and cow manure, through anaerobic digestion (AD). The main objective of this thesis was to investigate which operating parameters (e.g. LÄS MER

7. 5. Application of volatile fatty acids from waste as an external carbon source for the denitrification process

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

   Författare :Chengyang Pan; [2019]
   Nyckelord :Volatile fatty acids VFAs ; Denitrification; External carbon sources; Wastewater treatment; Manometric method; Flyktiga fettsyror VFAs ; Denitrifikation; Externa kolkällor; Avloppsrening; Manometrisk metod;

   Sammanfattning : The gap between resource demand for the industrialized world and non-renewable feedstock like fossil fuels, essential agricultural fertilizer is getting increasingly severe, which has resulted in alarming-increasingly impacts on worldwide environmental problems. Meanwhile, wastewater treatment plants (WWTPs), as an essential facility for urbanization, is also confronting new rising challenges such as energy consumption and operation costs rather than only improving effluent wastewater quality.
