6. Effect of substrate types on fermentation of mixed cultures to produce volatile fatty acids
University essay from KTH/Industriell bioteknologiAbstract : 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.

7. Ozone oxidation of fatty acid thin films: a TIR Raman study
University essay from KTH/Yt- och korrosionsvetenskapAbstract : Detta examensarbete initierades och handledes av Mellifiq, ett företag som arbetar med rening av luft och vatten, där en applikation är rening av köksfrånluft med ozon. Ozon förhindrar att fettpartiklar i frånluften ansamlas på väggarna i kanalen och värmeväxlaren, vilket leder till högre brandsäkerhet och mer effektiv användning av värmeväxlaren. READ MORE

8. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge
University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)Abstract : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

9. Implementation of a straightforward derivatizationmethod for the simultaneous analysis of short chainfatty acids and tricarboxylic acid cycle metabolitesby LC-qToF-MS.
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : Short-chain fatty acids (SCFAs) and the tricarboxylic acid (TCA) cycle metabolites aresmall hydrophilic compounds that play crucial roles in biological species ranging fromenergy metabolism, immune homeostasis to cellular signalling. There is a need for reliableand precise quantification of these metabolites in biological matrices as they can providecrucial information of metabolic status and potentially be used as diagnostic biomarkersfor different pathological and physiological conditions.

10. Comparison of mesophilic and thermophilic anaerobic sludge digestion at Hammarby Sjöstadsverk MBR pilot plant for wastewater treatment
University essay from SLU/Department of Molecular SciencesAbstract : Anaerobic digestion is a commonly used method for stabilisation of sewage sludge and production of biogas at municipal wastewater treatment plants (WWTPs). The hydraulic retention time for sludge in the digestion reactors is about 16 days at Henriksdal WWTP in Stockholm. READ MORE
