  2. 1. Industrial Bioprocess Developments for Biogas and Ethanol Production

    Author : Karthik Rajendran; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; ethanol; process design; techno-economic analysis; simulation; modeling; Resource Recovery; Resursåtervinning;

    Abstract : Current biofuels face a noteworthy misfortune on commercialization because of its economiccomparison with low-cost fuel from the oil reserves. To compete with gasoline as a fuel, thebiofuels need to be economically feasible and demonstrated on a large-scale. READ MORE

  4. 2. Biological Production of Hydrogen and Methane: Process Evaluation and Design through Modeling

    Author : Mattias Ljunggren; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biological hydrogen production; dark fermentation; photofermentation; process simulation; economic evaluation; gas upgrading; anaerobic digestion;

    Abstract : A great deal of research is being carried out on the biological production of hydrogen and methane. However, little effort has been devoted to studying the technical and economic feasibility of these processes. READ MORE

  5. 3. Biofilms in Nitrogen Removal - Bacterial Population Dynamics and Spatial Distribution

    Author : Robert Almstrand; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AOB; NOB; biofilms; image analysis; FISH; Nitrosomonas; population dynamics; spatial distribution;

    Abstract : Efficient nitrogen removal at wastewater treatment plants (WWTPs) is necessary to avoid eutrophication of recipient waters. The most commonly used approach consists of aerobic nitrification and subsequent anaerobic denitrification resulting in the release of dinitrogen gas into the atmosphere. READ MORE

  6. 4. Recursive black-box identification of nonlinear state-space ODE models

    Author : Linda Brus; Bengt Carlsson; Torbjörn Wigren; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Nonlinear system identification methods is a topic that has been gaining interest over the last years. One reason is the many application areas in controller design and system development. However, the problem of modeling nonlinear systems is complex and finding a general method that can be used for many different applications is difficult. READ MORE

  7. 5. Industrial Systems Biology and Metabolic Engineering of Saccharomyces cerevisiae

    Author : José Manuel Otero; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metabolic engineering; industrial systems biology; Saccharomyces cerevisiae;

    Abstract : Saccharomyces cerevisiae is the most well characterized eukaryote, the preferred microbial cell factoryfor the largest industrial biotechnology product (bioethanol), and a robust commercially compatible scaffold to be exploited for diverse chemical production. Succinic acid is a highly sought after added-value chemical whichis not overproduced in native S. READ MORE
