    Sammanfattning : Important aspects of ethanol production from undetoxified dilute acid lignocellulose hydrolysate are covered in this thesis, which primarily focuses on the use of Saccharomyces cerevisiae (Baker's yeast) as the biocatalyst. Nine different strains of S. LÄS MER

  3. 2. Enhanced Methane and Hydrogen production in Reverse Membrane Bioreactors via Syngas Fermentation

    Författare :Konstantinos Chandolias; Hariklia N. Gavala; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; syngas fermentation; CH4; H2; cell washout; inhibitors; mass transfer; Resource Recovery; Resursåtervinning;

    Sammanfattning : of waste treatment processes, such as the anaerobic digestion. This biochemical process converts organic substrates into biogas, with anaerobic microorganisms. However, some types of substrates have low bio-degradability due to its recalcitrance or the presence of inhibitors. LÄS MER

  4. 3. The asthmatic airway response – effects on physiology and biomarkers

    Författare :Henning Stenberg; allergologi och palliativ medicin Lungmedicin; []
    Nyckelord :Asthma; Exhaled breath temperature; Exercise; Allergen challenge; Small airways; Airway provocations; Spirometry; Impulse oscillometry; Inert gas washout; Body plethysmography; Club cell protein CC16 ;

    Sammanfattning : Asthma is a common airway inflammatory disease, associated with a variable degree of airway obstruction. It is a heterogeneous condition with large variations in severity and clinical presentation. Moreover, disease activity can vary from time to time. Taken together, these factors make the diagnosis, monitoring and treatment of asthma challenging. LÄS MER

  5. 4. Clinical aspects on glucose-lowering therapies in type 2 diabetes

    Författare :Åsa Nybäck-Nakell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Type 2 diabetes is a progressive disease with deterioration of glycaemic control over time in association with loss of endogenous insulin secretion. As a consequence of this, sulphonylureas (SU), which exert their mode of action by stimulating the pancreatic β-cells, are expected to be less effective with longer duration of diabetes. LÄS MER

  7. 5. Anaerobic Digester Fluid Rheology and Process Efficiency : Interactions of Substrate Composition, Trace Element Availability, and Microbial Activity

    Författare :Luka Šafarič; Annika Björn; Sepehr Shakeri Yekta; David Bastviken; David C Stuckey; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Anaerobic digestion; biogas; rheology; trace elements; microbiology; Anaerob rötning; biogas; reologi; spårämnen; mikrobiologi;

    Sammanfattning : As the anthropogenic greenhouse gas emissions continue imposing stress on our environment, it is becoming increasingly important to identify and implement new renewable technologies. Biogas production through anaerobic digestion has a great potential, since it links waste treatment with extraction of renewable energy, enabling circular bio-economies that are vital for a sustainable future.
