2. 16. Novel binding specificities engineered into the scaffold of a carbohydrate binding module

   Author : Lavinia Cicortas Gunnarsson; Institutionen för immunteknologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bioteknik; Biotechnology; carbohydrate binding module; binding specificity; selection; combinatorial library; scaffold; protein engineering;

   Abstract : The growing field of biotechnology is in constant need of proteins that can function as recognition tools for separational, analytical and therapeutic purposes. Different molecular engineering approaches are applied on natural proteins in order to create variants with desired properties. READ MORE

4. 17. Biorefining of lignocellulose : Detoxification of inhibitory hydrolysates and potential utilization of residual streams for production of enzymes

   Author : Adnan Cavka; Leif J. Jönsson; John N. Saddler; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Lignocellulosic biomass is a renewable resource that can be utilized for the production of biofuels, chemicals, and bio-based materials. Biochemical conversion of lignocellulose to advanced biofuels, such as cellulosic ethanol, is generally performed through microbial fermentation of sugars generated by thermochemical pretreatment of the biomass followed by an enzymatic hydrolysis of the cellulose.

5. 18. Improvement on cellulose accessibility and reactivity of different wood pulps

   Author : Viviana Köpcke; Monica Ek; KTH; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; cellulose; accessibility; reactivity; enzymatic treatment; mechanical treatment; chemical treatment; dissolving pulp; paper grade pulps; Wood fibre and forest products; Träfiber- och virkeslära;

   Abstract : Cellulosans tillgänglighet och reaktivitet är nyckelparametrar vid framställning av regenererad cellulosa och cellulosaderivat. Det är välkänt att på grund av cellulosans kristallina struktur är tillgängligheten begränsad för lösningsmedel och olika reagens. READ MORE

6. 19. Valorisation of cereal by-products: a biorefinery approach

   Author : Reskandi C. Rudjito; Franscisco Vilaplana; Amparo Jimenez-Quero; Mirjam Kabel; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cereal by-products; arabinoxylan; ferulic acid; subcritical water extraction; enzymatic treatment; xylanases; prebiotics; Jordbruksbiprodukter; arabinoxylan; ferulsyra; subkritisk vattenextraktion; enzymatisk behandling; xylanaser; prebiotika; Bioteknologi; Biotechnology;

   Abstract : Cereal by-products are abundant streams of underutilised biomass that have the potential be valorised into various industrial products by means of environmentally friendly processes. In this study, an integrated bioprocess combining subcritical water extraction (SWE) and enzymatic treatment (ET) was proposed to effectively extract arabinoxylans (AX) from cereal by-products.
