  1. 1. Tethered Lipid Vesicles as Nanoscale Sensor Elements

    University dissertation from Chalmers University of Technology

    Author : Seyed Tabaei; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antiviral peptide; aquaporin; aquaglyceroporin; biosensing; cell membrane; lipid bilayer; lipid vesicles; microfluidics; phospholipase A2; pore formation; surface plasmon resonance SPR ; total internal reflection fluorescence TIRF microscopy;

    Abstract : The primary aim of this thesis work has been to explore and advance the potential of surface tethered lipid vesicles as a platform for studying in particular the following three biomembrane-related processes: trans-membrane transport, membrane-peptide interactions and the activity of membrane active enzymes. First, a method based on surface plasmon resonance (SPR) spectroscopy was developed for studying passive diffusion processes as well as the membrane-protein mediated transport of small non electrolyte molecules across lipid bilayers.

  2. 2. Towards More Robust Saccharomyces cerevisiae Strains for Lignocellulosic Bioethanol Production: Lessons from process concepts and physiological investigations

    University dissertation from Chalmers University of Technology

    Author : Magnus Ask; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulosic bioethanol; SHF; SSF; Arundo donax; spruce; furfural; HMF; redox metabolism; transcriptome; glutathione;

    Abstract : Dwindling oil reserves and the negative impacts of fossil fuels on the environment call for more sustainable energy sources. First-generation bioethanol produced from sugar cane and corn has met some of these needs, but it competes with the food supply for raw materials. READ MORE

  3. 3. Concepts for improving ethanol productivity from lignocellulosic materials encapsulated yeast and membrane bioreactors

    University dissertation from Chalmers University of Technology

    Author : Päivi Ylitervo; Högskolan i Borås.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resource Recovery; Resursåtervinning; Encapsulated yeast; Biofuel; S. cerevisiae; Membrane bioreactors; Thermotolerance; Furfural; Acetic acid; Resource Recovery;

    Abstract : Lignocellulosic biomass is a potential feedstock for production of sugars, which can be fermented into ethanol. The work presented in this thesis proposes some solutions to overcome problems with suboptimal process performance due to elevated cultivation temperatures and inhibitors present during ethanol production from lignocellulosic materials.

  4. 4. Aroma and Flavor in Liquid Beet Sugar Processing

    University dissertation from Chalmers University of Technology

    Author : Per Pihlsgård; Chalmers tekniska högskola.; Chalmers University of Technology.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Bioengineering; liquid beet sugar; liquid beet sugar process; aroma; flavor; sensory analysis; GC-MS; GC-olfactometry; aroma release; macromolecules; electronic nose;

    Abstract : Production of liquid beet sugar, a product of increasing importance for the food industry, involves many different compounds exhibiting aroma. Aroma compounds are introduced with the raw material, the sugar beets, but also formed as a result of sugar degradation (caramelization and Maillard reaction) or by contamination from process steps, such as adsorbents and ion exchangers.

  5. 5. Vision Based Perception for Mechatronic Weed Control

    University dissertation from Chalmers University of Technology

    Author : Björn Åstrand; Högskolan i Halmstad.; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Vision-based perception; Plant recognition; Row following; Weed Control; Mechatronics in agriculture; Mobile robots; Informationsteknik; Information technology;

    Abstract : The use of computer-based signal processing and sensor technology to guide and control different types of agricultural field implements increases the performance of traditional implements and even makes it possible to create new ones. This thesis increases the knowledge on vision-based perception for mechatronic weed control. READ MORE
