2. 6. Sanitisation of faecal sludge by ammonia : treatment technology for safe reuse in agriculture

   Author : Jörgen Fidjeland; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Faecal sludge contains valuable plant nutrients and can be used as a fertiliser in agriculture, instead of being emitted as a pollutant. As this involves a risk of pathogen transmission, it is crucial to inactivate the pathogens in faecal sludge. One treatment alternative is ammonia sanitisation, as uncharged ammonia (NH₃) inactivates pathogens. READ MORE

4. 7. Sequence- and structure guided engineering of proteins and enzymes for biotechnology and health applications

   Author : Karen Schriever; Per-Olof Syrén; Elton P. Hudson; Eric A. Gaucher; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein engineering; enzymology; ancestral sequence reconstruction; antigen engineering; structural biology; terpene cyclases; enzyme thermodynamics; biocatalysis; phosphatases; allosteric regulation; Biotechnology; Bioteknologi;

   Abstract : Proteins are highly diverse and sophisticated biomolecules that represent a cornerstone of biological structure and function and have been exploited in man-made applications for thousands of years. Those proteins that facilitate chemical reactions at physiologically relevant time-scales are referred to as enzymes. READ MORE

5. 8. Engineering enzymes towards biotherapeutic applications using ancestral sequence reconstruction

   Author : Natalie Hendrikse; Per-Olof Syrén; Johan Rockberg; Erik Nordling; Reinhard Sterner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; enzyme engineering; enzyme evolution; ancestral sequence reconstruction; therapeutic enzymes; terpene cyclases; ammonia-lyases; sulfatases; lysosomal enzymes; Kemi; Chemistry;

   Abstract : Enzymes are versatile biocatalysts that fulfill essential functions in all forms of life and, therefore, play an important role in health and disease. One specific application of enzymes in life science is their use as biopharmaceuticals, which typically benefits from high catalytic activity and stability. READ MORE

6. 9. Protein Engineering of Candida antarctica Lipase A : Enhancing Enzyme Properties by Evolutionary and Semi-Rational Methods

   Author : Anders G. Sandström; Jan-Erling Bäckvall; Uwe T. Bornscheuer; Stockholms universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lipase; protein engineering; directed evolution; kinetic resolution; structural biology; Enzyme engineering; Enzymteknik; organisk kemi; Organic Chemistry;

   Abstract : Enzymes are gaining increasing importance as catalysts for selective transformations in organic synthetic chemistry. The engineering and design of enzymes is a developing, growing research field that is employed in biocatalysis. READ MORE

7. 10. Activation of dissolving pulps prior to viscose preparation

   Author : Niklas Kvarnlöf; Ulf Germgård; Leif J. Jönsson; Carl-Axel Söderlund; Herbert Sixta; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dissolving pulp; enzyme; reactivity; viscose; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

   Abstract : The conventional viscose manufacturing process is a mature process that needs to be improved with respect to its environmental impact and its production cost structure. Therefore a research study has been done with the aim to improve the reactivity of the dissolving pulp used, in order to reduce the chemical demand in the viscose process and thus reduce the cost and indirectly the environmental impact.
