  1. 1. Non-alcoholic beer with maltose negative yeast strain Saccharomycodes ludwigii

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Lucas Lissner; [2018]
    Keywords : Non-alcoholic beer; Saccharomycodes ludwigii; Changed mashing; food technology; livsmedelsteknologi; Chemistry; Technology and Engineering;

    Abstract : Non-alcoholic beer is gaining more attention in the brewing industry due to the negative health and economic consequences of alcohol consumption, even smaller microbreweries are showing interest in the production of non-alcoholic beer. Producing non-alcoholic beer has been restricted to the large breweries due to the special equipment needed and the high investment costs, but by using biological methods the process can be adapted to a traditional brewing setup.

  2. 2. Fodder yeast and biogas production: A fruitful symbiosis? : optimization of a single-cell protein process and examination of its impact on biogas output

    University essay from SLU/Dept. of Microbiology

    Author : Jonas Ohlsson; [2016]
    Keywords : fodder yeast; biogas; nutrient recycling; Wickerhamomyces anomalus; Pichia kudriavzevii; Blastobotrys adeninivorans;

    Abstract : Due to a growing world population and strained wild fish stocks, aquaculture is expected to provide a large part of the increased global demand for animal protein, as the majority of wild fish stocks are already being fished at or above their sustainable capacity. However, fish feed often contains a significant amount of fish meal, produced from wild-caught fish. READ MORE

  3. 3. Investigation of the Impact on Yeast Fermentation Performance in Production of Pale Lager Beer through Management Control

    University essay from Linköpings universitet/Teknisk biologiLinköpings universitet/Tekniska högskolan

    Author : Zara Skogsberg; [2013]
    Keywords : Yeast Fermentation; Full Factorial Design; Wort Aeration; Yeast Dosage; Ester Production; Yeast Viability;

    Abstract : Through a full factorial design experiment, the effects of time between worts, wort aeration and yeast dosage in production of a pale lager beer were examined in the beer process at Spendrups Bryggeri AB. The aim was to learn how different parameters may affect the yeast fermentation performance during beer production. READ MORE

  4. 4. Evaluation of Different Enzymes and Yeasts, and Their Impact on Bioethanol Production Based on Debranned Wheat

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Lina Lindberg; [2009]
    Keywords : Bioethanol; debranned wheat; α-amylase; glucoamylase; protease; baker’s yeast; Ethanol Red; AmyloFerm; HPLC; GC; viscosity;

    Abstract : Bioethanol is a fuel of tomorrow, and progress in the use of enzymes and reduction of non-fermentable materials by debranning will probably be a part to make it more economical with low environmental impact. Ethanol production based on debranned wheat was optimized in this study by batch experiments as well as continuous experiments in laboratory scale.

  5. 5. Concentrating lignocellulosic hydrolysate by evaporation and its fermentation by repeated fedbatch using flocculating Saccharomyces cerevisiae

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

    Author : Anahita Dehkhoda; [2008]
    Keywords : concentrating; lignocellulosic hydrolysate; evaporation; flocculating; yeast; fermentation; ethanol;

    Abstract : In order to obtain a sugar concentration of more than 100g.l-1of fermentable sugars, aspruce wood hydrolysate was subjected to high pressure and vacuum concentration andthe fermentability of each hydrolysate was assessed by fermentation experiments withflocculating S. cerevisiae.
