  1. 1. Composition and processability of milk from older cows : a pilot study on milk quality differences between young and old cows

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Gabriella Apelthun; [2020]
    Nyckelord :Raw milk quality; lactation number; gel firmness; rennet coagulation time; Swedish Holstein; Swedish Red;

    Sammanfattning : Most Swedish dairy cow’s life expectancy is five years, which is 2.5 lactations. The most common reason for dairy cows being culled are e.g. LÄS MER

  3. 2. Combined production of bioethanol and biogas from wheat straw

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Victor Gustafson; [2015]
    Nyckelord :lactic acid; chemical engineering; biogas; enzymes; enzymatic hydrolysis; energy recovery; ethanol red; bioethanol; wheat straw; steam pretreatment; inhibitors; kemiteknik; Technology and Engineering;

    Sammanfattning : Currently the production cost of lignocellulosic ethanol is considered to be relatively high. Large fractions of the production cost come from the raw material and the energy consumed in the distillation. Therefore it is desirable to have a process that yields high concentration of ethanol and maximizes the utilization of the biomass. LÄS MER

  4. 3. Investigation of yeast Grown in SSF Dring Biothanol Production from Lignocellusosic Material

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Ayda Barid Babapour; Maryam Nadalipour Gavitar; [2012]
    Nyckelord :SSF; yeast; ethanol; lignocellulosic; fermentation; hardwood; lactic acid; pentose fermenting; contamination;

    Sammanfattning : Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.

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

    Master-uppsats, Institutionen för fysik, kemi och biologi

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

    Sammanfattning : 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.

  7. 5. Probing Control of Glucose Feeding in Cultivation of Saccharomyces cerevisiae

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :John Fredriksson; [2001]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In order to maximize the biomass yield in fed-batch cultivations of Saccharomyces cerevisiae, a pulse feeding strategy originally developed by Mats Åkesson at the department of automatic con-trol (Åkesson, 1999), was implemented. The controller was intended to keep the specific glucose uptake rate, qs, below the critical specific glucose uptake rate qs crit , to avoid over-flow metabolism. LÄS MER
