1. Too close for comfort : The role of Contact-Dependent growth Inhibition (CDI) in interbacterial competition and cooperation
Sammanfattning : Contact-Dependent growth inhibition (CDI) was discovered in 2005 in the E. coli isolate EC93. Since then our knowledge of CDI systems and their impact on bacterial communities have increased exponentially. LÄS MER
2. Antibiotic resistance in Gram-negative bacilli : with focus on cephalosporin resistance mechanisms in Escherichia coli and Klebsiella pneumoniae
Sammanfattning : Objectives: The objectives of this thesis were to study mechanisms conferring cefuroxime resistance in clinical non-ESBL (extended-spectrum beta-lactamase) producing isolates of Escherichia coli and Klebsiella pneumoniae, as well as the presence of co-resistance to other antibiotics in the K. pneumoniae isolates.

3. Lead(II) as a Tool for Probing RNA Structure in vivo
Sammanfattning : Chemical modification and limited enzymatic hydrolysis are powerful methods to obtain detailed information on the structure and dynamics of RNAs in solution. In the work presented here I have taken advantage of the properties of the divalent metal ion lead(II) to establish it as a new probe for investigating the structure of RNA in vivo. LÄS MER
4. Growth rate control of periplasmic product retention in Escherichia coli
Sammanfattning : The recombinant product is secreted to the periplasm in many processes where E. coli is used as host. One drawback with secretion is the undesired leakage of the periplasmic products to the medium. The aim of this work was to find strategies to influence the periplasmic retention of recombinant products. LÄS MER
