  1. 21. The effect of ration forage proportions on the microbial ecology of the Rumen

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Rasmus Vihermäki; [2019]
    Keywords : ekologi; grovfoder; kraftfoder; VFA; acidos; idisslare;

    Abstract : Grovfoder utgör en stor del av kons foderintag och dess struktur är viktig för kons hälsa. En foderstat som till största delen innehåller kraftfoder främjar tillväxten av exempelvis Lactobacilli och Streptococcus bovis (S.bovis) som i sin tur producerar laktat. Laktat sänker pH i vommen och kan leda till vomacidos. READ MORE

  3. 22. Production of volatile fatty acids from anaerobic digesting using food waste and sludge

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

    Author : Seyed Reza Manafi Khosroshahi; [2019]
    Keywords : ;

    Abstract : Volatile fatty acids (VFAs) have gained a very extensive research interest since they are important building blocks for the chemical industry. This acids can be produced via anaerobic digestion (AD) which have shown to be an environmental friendly process since it utilizes waste products such as sludge and food waste as substrate.

  4. 23. Anaerobic degradation of volatile fatty acids in continuous biogas reactors at very short hydraulic retention times.

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Anna Lea Auguste Weimer; [2019]
    Keywords : Anaerobic digestion; hydraulic retention time; organic loading rate; biogas; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : There is an increasing demand for safe, affordable and above allsustainable energy, due to the exhaustion of fossil fuels and increasing greenhousegas emissions. In this context, anaerobic digestion is of growing interest, as it enablesthe production of the versatile renewable energy source biogas from various types oforganic wastes. READ MORE

  5. 24. Biohydrogen and Volatile Fatty Acids Production form Food Waste Hydrolysate

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Yaswanth Lingam; [2018]
    Keywords : Biohydrogen; Food waste; volatile fatty acids; acetic acid; wastewater;

    Abstract : This work focused a pH readjustment strategy has been applied for the enhancement ofbiohydrogen production form food waste hydrolysate in a semi-pilot scale bioreactor seededwith selectively enriched mixed microbial culture. Different initial pH (pH 6, pH 7, and pH8) was selected for biohydrogen production from FW. READ MORE

  6. 25. Comparison of anaerobic sludge granules from different wastewater plants with respect to granule size, substrate degradation and methanogenic community

    University essay from SLU/Department of Molecular Sciences

    Author : Jonathan Andrén; [2018]
    Keywords : anaerobic digestion; granule; UASB; EGSB; VFA; methanogen; acetoclastic; hydrogenotrophic; acetogenic; mcrA; ; T-RFLP; methanosarcina; methanosaeta;

    Abstract : Within the objective to replace fossil fuel with sustainable sources there is a growing pressure to advance such development. Anaerobic digestion (AD) is beneficial not only as a waste management technology, but also to recycle organic waste into methane which can be used for heating, production of electricity or vehicle fuel.
