2. 1. Bioprocessing of Oats Influence on Phytate Hydrolysis and Mineral Bioavailability

   Author : Marie Larsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zinc absorption; bread fermentation; oats; bioprocessing; malting; iron absorption; mineral bioavailability; phytase activity; phytate;

   Abstract : The effects of bioprocessing on enzymatic phytate hydrolysis in oats were studied during malting, soaking and breadmaking to elucidate the reasons for poor phytase activity in oats and determine the optimal conditions for phytate hydrolysis. Malting of oats in a pilot plant was studied to investigate whether the malting process developed in the laboratory could be used in large scale preparation of oats with reduced phytate content.

4. 2. Cryogels as Solid Supports in Bioprocessing

   Author : Gry Jespersen; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Downstream processing; cryogel; solid support; biomacromolecules; chromatography;

   Abstract : In recent years the market for biopharmaceutical products has been increasing rapidly as a result of an increased demand for new and efficient treatments of various indications. Biopharmaceuticals are distinguished from chemical drugs by being derived from a biological origin and are hence, frequently constituting biological macromolecules. READ MORE

5. 3. Bioprocessing, Structure and Material Properties of Arabinoxylans

   Author : Anders Höije; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture content; biorefinery; Arabinoxylan; mechanical properties; chemical structure; isolation; film formation; oxygen permeability; enzymatic treatment;

   Abstract : This work has focused on using agriculture residues as raw material for new polymeric materials. Arabinoxylans have been isolated from barley husks and endosperm fiber using alkali extraction, and the chemical composition and detailed structure have been determined. READ MORE

6. 4. 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.

7. 5. Waste Textiles Bioprocessing to Ethanol and Biogas

   Author : Azam Jeihanipour; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; biogas; biorefinery; cellulose recalcitrance; cotton-based cellulose; enzymatic hydrolysis; pretreatment; recycling; waste textile; Resursåtervinning; Resursåtervinning; Resource Recovery;

   Abstract : The work of the present thesis focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. READ MORE
