1. Biogasproduktion vid samrötning av substrat tillgängliga vid lantbruk : Småskalig rötning vid Lillerudsgymnasiet
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : The world is currently heavily dependent on fossil sources and the use of fossil fuels leads to increased global warming. One of the solutions to this environmental problems is biogas. LÄS MER
2. Effekten av flyktiga fettsyror (VFA) på tillväxten av mikroalger
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Anaerob jäsning antas vara en bra och effektiv metod för behandling av organiskt avfall. Avloppsvatten från denna process är mer utmanande beroende främst på dess höga innehåll av bland annat flyktiga fettsyror (VFA). LÄS MER
3. Cultivation of Yarrowia lipolytica on a hydrolysate based on food waste
Master-uppsats, SLU/Department of Molecular SciencesSammanfattning : Interest in replacing fish oil and fish meal as fish feed ingredients with more socially, environmen-tally, and economically sustainable alternatives has increased in recent years. One such alternative could be the use of yeast biomass. LÄS MER
4. Using biological conversion to increase the value of short-chain fatty acids by mixed cultures
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : The development of anaerobic digestion processes has gained recognition for its potential for producing volatile fatty acids alongside bio-alcohols. In addition, the fermentation process and the products produced from biological fermentation have the possibility to overcome the abundance of organic waste in our society, which is potentially immensely rich in untapped valuable potential products.

5. Isolation of an ammonia-tolerant syntrophic butyrate-oxidizing bacterium originating from a thermophilic biogas digester
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Syntrophic relationships between fatty acid degrading bacteria and hydrogenotrophic methanogens are important for a well-functioning anaerobic degradation process during biogas production from organic waste material. This is particularly important in biogas processes fed protein-rich material as their degradation gives rise to high levels of ammonia, which inhibits many microorganisms. LÄS MER
