2. 1. Stress response in the cyanobacterium Synechocystis sp. PCC 6803

   Author : Helder Miranda; Christiane Funk; Hans-Erik Åkerlund; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; High light; heat stress; ROS; Photosynthesis; Photosystem II; Deg HtrA proteases; small CAB-like proteins; Refraction-2D™; MALDI-TOF; 2D-gel; GC-MS; PCA; OPLS-DA; EPS; S-layer; Biochemistry; Biokemi; biokemi; Biochemistry;

   Abstract : Adaptation to environmental changes is important for the survival of living organisms. Under extreme abiotic conditions, organic molecules (such as lipids, proteins and nucleic acids) are prone to damage. READ MORE

4. 2. Improvement of Wastewater Sludge Digestion

   Author : Michael Recktenwald; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anaerobic digestion; biogas; cation-binding agents; enzymes; enzymatic activity; extracellular polymeric substances EPS ; industrial scale trials; methanization; municipal sewage; sludge treatment; wastewater treatment plant;

   Abstract : The reduction of sludge volumes for disposal is a topic of high interest for wastewater treatment plants (WWTP) all over the world. Steadily increasing volumes for disposal create an economic, environmental, legislative and technological challenge. READ MORE

5. 3. Homopolysaccharide metabolism in Lactobacillus reuteri and Pediococcus parvulus

   Author : Emma Årsköld; Teknisk mikrobiologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virology; bacteriology; Carbohydrate metabolism; Exopolysaccharides; Lactic acid bacteria; Mikrobiologi; bakteriologi; virologi; mykologi; mycology; Microbiology;

   Abstract : This thesis deals with the central carbohydrate metabolism and exopolysaccharide (EPS) formation in two different lactic acid bacteria (LAB): Lactobacillus reuteri and Pediococcus parvulus. LAB are traditionally used as starter cultures in the food industry. In general, LAB harbours one glycolytic pathway converting carbohydrates into lactic acid. READ MORE

6. 4. Biosynthesis of bacterial polysaccharides by novel glycosyltransferase enzymes

   Author : Shu-Chieh Chang; Yves S. Y. Hsieh; Ute Römling; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Bioteknologi;

   Abstract : Within the intricate microbiological realm, exopolysaccharides (EPS) emerge as a significant class of high molecular weight polysaccharides, serving pivotal roles in bacterial survival, virulence, communication, and defense against environmental adversities. The versatile nature of bacterial EPS extends beyond mere biological functions, reaching into medications, cosmetics, functional food, and sustainable industries. READ MORE

7. 5. Metabolic Engineering of the Central Carbon Metabolism in Streptococcus thermophilus for Enhanced Exopolysaccharide Production

   Author : Malin Svensson; Teknisk mikrobiologi; []

   Abstract : The lactic acid bacterium, Streptococcus thermophilus, is used in the dairy industry in mixed cultures with Lactobacillus delbrueckii subsp. bulgaricus for the production of yoghurt. Many strains of S. thermophilus produce exopolysaccharides (EPSs) which affect the texture and viscosity of fermented food products. READ MORE
