  2. 1. Development of Simultaneous Saccharification and Fermentation for Production of Ethanol from Softwood

    Author : Malek Alkasrawi; Centrum för analys och syntes; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Kemiteknik och kemisk teknologi; spruce; softwood; fermentation; cultivation; Tween-20; SSF; recirculation; Ethanol production; process streams;

    Abstract : This thesis deals with the development of simultaneous saccharification and fermentation (SSF) in order to improve the economy of the softwood-to-ethanol process. The effect of process stream recirculation on ethanol production from steam-pretreated softwood based on SSF was investigated for two process cases. READ MORE

  4. 2. Enzyme Immunoassay in Combination with Liquid Chromatography for Sensitive and Selective Determination of Drugs in Biosamples

    Author : Ulf Lövgren; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; amplification; alkaline phosphatase; enzyme immunoassay; liquid chromatography; flow-injection; micellar; Analytisk kemi;

    Abstract : Two different sensitive microtitre-plate based enzyme immunoassays were developed and evaluated for determination of the model drug compound, budesonide, in blood plasma. In the first approach, high sensitivity was obtained by using amperometric detection in a flow injection system for determination of the enzyme product p-aminophenol. READ MORE

    Abstract : Capillary-based platforms for diagnostics are popular for the point-of-care diagnostics market because of their low cost, easy fabrication, and easy operation. Lateral flow tests are an excellent example of capillary-based platforms for point-of-care diagnostics. READ MORE

  6. 4. Enhanced Enzymatic Hydrolysis of Lignocellulose in Bioethanol Production Substrate Interactions with Surfactants and Polymers

    Author : Johan Börjesson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enzymologi; Penicillium brasilianum; SSF; Ethanol; Proteins; enzymology; Proteiner; Protease; Adsorption; PEG; Surfactant; Hydrolysis; Lignocellulose; Cellulase; Hypocrea jecorina; Trichoderma reesei; Cellulose;

    Abstract : Ethanol produced from cellulose is a promising future alternative fuel. The production process has three main steps: (i) pretreatment of raw material to increase degradability; (ii) enzymatic hydrolysis of cellulose to produce glucose; (iii) fermentation of glucose into bioethanol.
