  2. 11. Promoting healing of skin and mucosa by immunomodulation using CXCL12 producing lactic acid bacteria : From bench to bedside

    Author : Emelie Öhnstedt; Mia Phillipson; Neil Forbes; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; L.reuteri; wound healing; non-healing wounds; ILP100; colitis; immunotherapy;

    Abstract : Immunotherapies direct the immune system to respond in a certain way, such as to fight cancer or to dampen inflammation. In this thesis, a new immunotherapy, ILP100, is developed using a technology that allows for local production of short-lived immunoregulatory proteins that previously have been undruggable.

  4. 12. Fermentation of wheat starch hydrolysate by Lactococcus lactis: Factors affecting product formation

    Author : Karin Hofvendahl; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nutrients; temperature; pH; optical isomers; maltose; wheat; starch hydrolysate; Lactococcus lactis; lactic acid; SSF; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Lactic acid exists as two optical isomers, D- and L-lactic acid. For the production of biodegradable poly-lactic acid an optically pure product is desirable, but a racemate of known and constant ratio can also be used. Lactic acid can be produced either synthetically or fermentatively. READ MORE

  5. 13. Studies on the Physiological Effects of Microbial Exopolysaccharides

    Author : Cecilia Lindström; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Probiotics; Prebiotics; Microbiota; Glycemic regulation; Dietary fiber; Oats; Lactic acid bacteria;

    Abstract : The spread of lifestyle-related diseases has become epidemic throughout the world. Impaired glucose metabolism and high levels of plasma cholesterol are risk factors for the development of type 2 diabetes and cardiovascular disease respectively. READ MORE

  6. 14. 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

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

    Author : Malin Svensson; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; Biotechnology; Bioteknik; Biokemisk teknik; Biochemical technology; Analytisk kemi; Analytical chemistry; metabolism; Biokemi; Metabolism; mykologi; Biochemistry; virologi; Mikrobiologi; bakteriologi; virology; mycology; bacteriology; Streptococcus thermophilus; Microbiology; Metabolic engineering; Lactic acid bacteria; Exopolysaccharides; Central carbon metabolism;

    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
