2. 1. Strategies for improved Escherichia coli bioprocessing performance

   Author : Johan Jarmander; Gen Larsson; Thomas Egli; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; E. coli; Salmonella; surface expression; autotransport; AIDA-I; lignocellulose; glucose; xylose; arabinose; simultaneous uptake; 3HB; Bioteknologi; Biotechnology;

   Abstract : Escherichia coli has a proven track record for successful production of anything from small molecules like organic acids to large therapeutic proteins, and has thus important applications in both R&D and commercial production. The versatility of this organism in combination with the accumulated knowledge of its genome, metabolism and physiology, has allowed for development of specialty strains capable of performing very specific tasks, opening up opportunities within new areas.

4. 2. Exploring Yeast as a Cell Factory for the Production of Carboxylic Acids and Derivatives

   Author : Diogo Portugal-Nunes; Teknisk mikrobiologi; []
   Keywords : Saccharomyces cerevisiae; Poly-3-D-hydroxybutyrate PHB ; Carboxylic acids; Alpha-ketoglutarate AKG ; Xylose assimilation; Weimberg pathway;

   Abstract : Baker’s yeast, Saccharomyces cerevisiae, is a promising cell factory for the sustainable utilization of renewable resources for the formation of products with commercial value. Among these, poly-3-D-hydroxybutyrate (PHB) is an extensively studied biopolymer naturally accumulated in some bacteria and archaea species through the formation of carbon granules. READ MORE

5. 3. The role of sugar sensing and pathway selection on D-xylose utilization by Saccharomyces cerevisiae

   Author : Celina Tufvegren; Teknisk mikrobiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Biorefineries have the potential to partially or entirely replace petrochemistry for the production of our daily bulk and fine chemicals. However, this replacement can only be sustainable and cost-effective if the raw material used is cheap, renewable and does not compete with the food and feed industry. READ MORE

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

   Author : Magnus Ask; Chalmers tekniska högskola; []
   Keywords : 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; transcriptome; SHF; glutathione; SSF; furfural; redox metabolism; Arundo donax; Lignocellulosic bioethanol; spruce; HMF;

   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
