  1. 1. Production of filamentous fungal biomass on waste-derived volatile fatty acids for ruminant feed supplementation and it's in vitro digestion analysis

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Mohammadali Bouzarjomehr; [2022]
    Keywords : VFAs volatile-fatty-acids ; Fungi production; Feed production.; Fermentation processes; Aspergillus oryzae; A. oryzae fungal biomass; Sustainability; Rumen fluids; Evaluation of the digestibility of the produced fungal biomass; TT method analysis; Gas production method; Nylon bag method analysis;

    Abstract : Single cell proteins such as that of edible filamentous fungal biomass are considered as a promising sustainable source of animal feed supplementation. Filamentous fungi can be cultivated on different organic substrates including volatile fatty acids (VFAs) such as acetic, propionic, and butyric acids. READ MORE

  3. 2. Potential of waste-derived VFAs-bearing effluents as an external carbon source for MBBR denitrification of domestic wastewater

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Seyed Reza Manafi Khosroshahi; [2022]
    Keywords : Volatile fatty acids; Denitrification; Wastewater treatment; Biological nutrient removal; Nitrate removal; Electron accepter; Carbon source; Electron doner; Moving bed biofilm reactor; Nanofiltration; VFA concentration; Discharge standards; Carriers; acclimatization; VFAs; MMBR; NF; WWTP; BNR;

    Abstract : In conventional wastewater treatment plants, methanol, ethanol, and acetate are used as carbon source for the denitrification process in the biological nutrient removal. However, growing concern regarding economical costs and carbon footprints from the fossil-based production of these chemicals have forced the companies to look for other alternatives. READ MORE

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

    University essay from KTH/Industriell bioteknologi

    Author : Jayant Sehgal; [2022]
    Keywords : 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;

    Abstract : 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.

  5. 4. Evaluating the suitability of carbon source from fermentation of primary filter sludge for biological nutrient removal

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Sanna Sahlin; [2021]
    Keywords : Wastewater treatment; batch activity tests; NUR tests; anaerobic P release tests; EBPR; denitrification; removal rates; internal carbon source; fermentate; water and environmental engineering; Technology and Engineering;

    Abstract : Traditional biological nutrient removal (BNR) processes in wastewater treatment require access to easily biodegradable carbon in order to achieve sufficient removal. However, a lot of the carbon in the influent wastewater is not directly available for BNR bacteria but need to undergo hydrolysis first. READ MORE

  6. 5. Enhancement of hydrolysis from co-fermentation of food waste and primary sludge

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Johnny Hagelin; [2021]
    Keywords : Environmental engineering; Bioaugmentation; Fermentation; Hydrolysis; Resource recovery;

    Abstract : 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. READ MORE
