11. Våmacidos – den svårupptäckta sjukdomen : en studie kring hur sjukdomen uppkommer samt dess förekomst i Sverige
University essay from SLU/Dept. of Biosystems and Technology (from 130101)Abstract : För att mjölkkor ska ha en väl fungerande våm krävs en foderstat med en stor mängd fiberrika material som stimulerar till idissling. Vid en för hög tillförsel av stärkelse och en lägre andel fibrer i foderstaten kan mängden flyktiga fettsyror öka i våmmen. READ MORE

12. 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.

13. Evaluating the suitability of carbon source from fermentation of primary filter sludge for biological nutrient removal
University essay from Lunds universitet/Kemiteknik (CI)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

15. 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.
