2. 6. Comprehensive non-target screening to find and identify new biomagnifying organic contaminants in Baltic Sea top consumers

   Author : Andriy Rebryk; Peter Haglund; Christine Gallampois; Mats Tysklind; Jacob de Boer; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; persistent organic pollutants; contaminants of emerging concern; non-target screening; GC-MS; biomagnification; temporal trends; Analytical Chemistry; analytisk kemi; environmental science; miljövetenskap;

   Abstract : The development of industrial processes in the 19th and 20th centuries, in particular oil refining, resulted in a huge discovery and subsequent large-scale production of a variety of chemicals. These useful chemicals supposedly made the everyday lives of people easier and better by, for instance, controlling the spread of diseases such as malaria, through the use of DDT and other organochlorine pesticides (OCPs).

4. 7. Systems Analysis of Chemicals Production via Integrated Entrained Flow Biomass Gasification : Quantification and improvement of techno-economic performance

   Author : Jim Andersson; Eric D. Larson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Abstract : Lignocellulosic biomass gasification is a promising production pathway for green chemicals, which can support the development towards a more sustainable society where fossil fuels are replaced. To be able to compete with fossil fuels, a highly efficient production of biomassbased products is required in order to maximize overall process economics and to minimizenegative environmental impact.

5. 8. Hydrolases as Catalysts for Green Chemistry and Industrial Applications - Esterase, Lipase and Phytase

   Author : Yasser Gaber; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HPLC-EAT; sustainable environment; mutation; metallo-enzyme; phytate; b-propeller; biodegraqdable; metrics; green chemistry; Novozym 435; CalB; solvent-free; kinetic resolution; Biocatalysis; rational design; PLE; esterase; clopidogrel; enantioselectivity;

   Abstract : The use of enzymes in industrial applications has been recognised for providing clean processes with minimal impact on the environment. This thesis presents studies on engineering of enzymes and enzyme-based processes in the light of green chemistry and environmental sustainability, and focuses on three hydrolases: esterase, lipase and phytase.

   Abstract : Throughout history, people have used products from different microorganisms and plants for many medicinal and nutritional applications. Chilli peppers have been used for spicing up food, but also for their pharmacological properties. READ MORE

7. 10. Engineering yeast for improved recombinant protein production

   Author : Yanyan Wang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; point mutation; genome-scale modeling; recombinant protein; omics analysis; CRISPR Cas9; protein secretion; Saccharomyces cerevisiae;

   Abstract : Recombinant proteins are broadly used from basic research to therapeutic development and include industrial enzymes and pharmaceutical proteins. The increasing demand for improved production and enhanced quality of recombinant proteins requires robust biotech-based strategies to overcome the limitations of protein extraction from natural sources.
