2. 1. Microbial Production of Bio-Based Chemicals: A Biorefinery Perspective

   Author : Tarek Dishisha; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; platform chemical; organic acid; propionic acid; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; methacrylic acid; 1; 3-propanediol; Propionibacterium acidipropionici; Lactobacillus reuteri; Gluconobacter oxydans; high cell density fermentation; biotransformation; product inhibition; cell recycle; immobilized cells; chemical catalysis; pdu operon;

   Abstract : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. READ MORE

4. 2. Probing the Nano-Bio Interface Using Surface Based Analytical Techniques

   Author : Rickard Frost; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanotoxicology; cell membrane; nanomedicine; melanophores; QCM-D; nanomaterial; DPI; AFM; supported lipid bilayer;

   Abstract : In recent years, the use of manufactured nanomaterials has been rapidly increasing in a wide range of application areas. Among others, these areas of application include cosmetics, medicine, clothing, and sporting goods. The small size of nanomaterials offers unique properties that are not possible to obtain by the same material in bulk. READ MORE

5. 3. Exploring Anaerobic Bacteria for Industrial Biotechnology - Diversity Studies, Screening and Biorefinery Applications

   Author : Rosa Aragao; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic bacteria; industrial biotechnology; biorefinery; microbial diversity; single cell entrapment; llama rumen;

   Abstract : Depletion of easily accessible fossil energy resources, threat of climate change and political priority to achieve energy self-sufficiency and sustainable solutions prioritize a conscious and smart use of renewable resources to generate a bio-based economy. Bio-based compounds can replace chemicals and fuels that are now mainly produced from crude oil. READ MORE
