  2. 1. Physiological Engineering of Xylose Utilisation by Recombinant Saccharomyces cerevisiae

    Author : Nina Quednau Meinander; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein burden; physiology; fed-batch fermentation; chemostat; recombinant Saccharomyces cerevisiae; ethanol; xylose; xylitol; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Xylitol production by recombinant, XYL1-expressing Saccharomyces cerevisiae was investigated in fed-batch fermentation using different cosubstrates for growth, and generation of reduced cofactors and maintenance energy. Xylose was converted into xylitol with 1:1 yield. READ MORE

  4. 2. Beta-glucose 1-phosphate interconverting enzymes in Lactococcus lactis: physiological role and regulation in maltose, trehalose and glucose metabolism

    Author : Ulrika Andersson; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Biochemical technology; Biokemisk teknik; bacteriology; Microbiology; Kemiteknik och kemisk teknologi; Chemical technology and engineering; trehalose 6-phosphate phosphorylase; beta-phosphoglucomutase; maltose phosphorylase; glucose; trehalose; maltose; Lactococcus lactis; beta-glucose 1-phosphate;

    Abstract : Lactic acid bacteria (LAB), including Lactococcus lactis, are abundant in nature. These bacteria convert carbohydrates into mainly lactate by a rather uncomplicated metabolism. An improved understanding of the physiological and genetical mechanisms involved in carbohydrate metabolism and its regulation will improve the industrial use of LAB. READ MORE

  5. 3. Differentiation and Pathogenicity within the Saprolegniaceae : Studies on Physiology and Gene Expression Patterns in Saprolegnia parasitica and Aphanomyces astaci

    Author : Gunnar Andersson; Michael J. Bidochka; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zoophysiology; Zoofysiologi; Animal physiology; Zoofysiologi; fysiologisk mykologi; Physiological Mycology;

    Abstract : Saprolegnia parasitica and Aphanomyces astaci are parasitic water moulds belonging to the Oomycetes. Despite their importance as parasites they are very little studied at the molecular level and the work described in this thesis was aimed at increasing the molecular knowledge of these organisms by cloning and characterising genes of potential importance for reproduction and pathogenicity.

  6. 4. Plasminogen and protein PAM: Interactions between streptococcal surface proteins and the human fibrinolytic system

    Author : Annika Carlsson Wistedt; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteriology; Microbiology; M protein; streptokinase; kringles; plasmin; Streptococcus pyogenes; plasminogen; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Pathogenic bacteria often produce potent proteases capable of destroying host tissue thereby providing the bacteria with tools for spreading and nutrient access. This thesis describes how group A, C and G streptococci can acquire surface bound protease activity through an alternative mechanism, namely by binding and activation of the human protease precursor plasminogen.

  7. 5. Mechanisms of phagocytosis resistance in Streptococcus pyogenes

    Author : Heike Kotarsky; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; fibrinogen; FHL-1; Factor H; M protein; Streptococcus pyogenes; phagocytosis;

    Abstract : A distinguishing feature of Streptococcus pyogenes (GAS) is their ability to resist phagocytosis in whole human blood in the absence of type-specific antibodies, a property that is dependent on the expression of the surface associated M proteins. A common characteristic of M proteins is their interaction with a variety of host proteins including the complement regulatory protein factor H (FH) and fibrinogen that plays a key role in coagulation.
