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

    University essay from SLU/Department of Molecular Sciences

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE

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

    University essay from 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. 4. Probing Control of Glucose Feeding in Cultivation of Saccharomyces cerevisiae

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : John Fredriksson; [2001]
    Keywords : Technology and Engineering;

    Abstract : 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. READ MORE
