2. 11. Four carbon oxychemicals from renewable resources

   Author : Adam Marschall Jaros; Christian Andersson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

   Abstract : Butanol, butyric acid and butyraldehyde are important 4-carbon oxychemicals typically generated from petro-chemical sources. All have significant markets in the food industry either for direct use as flavorings or as chemical feedstocks for generating butyric acid and butyraldehyde derived flavour compounds. READ MORE

4. 12. Food-Related Gram-Positive Bacteria: Enterotoxin A Expression in Staphylococcus aureus and a New Regulation Mechanism in Lactococcus lactis

   Author : Rong Cao; Teknisk mikrobiologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactococcus lactis; multiple inhibition kinetics; dehydrogenase; ATP; ADP; food factors; biopreservatives; staphylococcal food poisoning; SEA; prophage induction; enterotoxin A; Staphylococcus aureus;

   Abstract : Staphylococcal enterotoxin A (SEA) is the most common enterotoxin found in outbreaks of staphylococcal food poisoning (SFP). Based on the amount of SEA produced, S. aureus strains were divided into two main groups, high- and low-SEA-producing strains. READ MORE

5. 13. Feeding Strategies Based on Probing Control for E. coli and V. cholerae Cultivations

   Author : Lena de Maré; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; control engineering; Automatiska system; robotteknik; reglerteknik; Automation; Temperature; Mid-ranging control; Amino acid; Complex media; Fed-batch bioreactors; Probing control; Biotechnology; Bioteknik; Parameter estimation; Feeding strategies;

   Abstract : The recombinant DNA techniques have made it possible to produce many different proteins for a wide range of applications. The vector encoding for the recombinant protein is often inserted in the bacterium E. coli as it is a well studied and a well-known organism. To achieve a high productivity, it is important to reach a high cell density. READ MORE

6. 14. Cassava Processing: Safety and Protein Fortification

   Author : Lucas Tivana; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cassava; Cyanogenic glycosides; aquacyano-cobyrinic acid; processing; amylose; amylopectin; protein; texture;

   Abstract : Cassava (Manihot esculenta Crantz) is an important and cheap source of carbohydrate in tropical regions, particularly in Sub-Sahara Africa. Cassava as a human food is a good source of energy as it has a comparable high energy density of about 610 kJ/100 g fresh root. READ MORE

7. 15. Anaerobic Digester Fluid Rheology and Process Efficiency : Interactions of Substrate Composition, Trace Element Availability, and Microbial Activity

   Author : Luka Šafarič; Annika Björn; Sepehr Shakeri Yekta; David Bastviken; David C Stuckey; Linköpings universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Anaerobic digestion; biogas; rheology; trace elements; microbiology; Anaerob rötning; biogas; reologi; spårämnen; mikrobiologi;

   Abstract : As the anthropogenic greenhouse gas emissions continue imposing stress on our environment, it is becoming increasingly important to identify and implement new renewable technologies. Biogas production through anaerobic digestion has a great potential, since it links waste treatment with extraction of renewable energy, enabling circular bio-economies that are vital for a sustainable future.
