Abstract:

Iron is a common cation in biomineral sand; it is present for example in magnetite produced by magnetotactic bacteria and in iron sulfides produced by sulfate reducing microorganisms. The work presented in this thesis focused on two types of microorganisms capable of forming iron biominerals. In the first project I have studied the effect of O2 on the respiratory physiology and the formation of magnetosomes by Magnetospirillum magneticum AMB-1. In the second project I have studied the relationship between olivine and the activity of dissimilatory sulfate reducing (DSR) microorganisms. For the

Using a mixture of bioinformatic analyses, microarrays on cells that were grown in media that were either replete or depleted for manganese or for iron, and by making targeted mutations and reporter fusions, several important observations were made on the mechanisms of Mn and Fe homeostasis in the marine α‐proteobacterium Ruegeria pomeroyi (the main species studied here), and in other important marine bacteria. R. pomeroyi lacks most of the known Fe uptake systems, including TonB and outer‐membrane receptors, but has a predicted, but incomplete iron uptake ABC‐class transporter operon, whose e

Abstract:

Campylobacter jejuni and Escherichia coli strain F11 are two Gram-negative pathogens with a versatile armament of iron uptake systems to cope with the fluctuating host nutrient environment. Our current understanding of Gram-negative iron uptake systems focuses heavily on a prototypical scheme involving a TonB-dependent outer membrane receptor and an ABC transporter, with little knowledge on systems that do not fall neatly into this paradigm. The primary focus of this thesis is the characterization of three such atypical iron uptake proteins from C. jejuni (ChaN and P19) and pathogenic E. coli

The aim of this study was to investigate the iron- and sulphur-oxidizing activities of thermophilic bacteria with reference to the possible use of such bacteria in the extraction of metals from mineral sulphides.

Abstract:

Ferric iron (Fe3+) can be used as a terminal electron acceptor by iron-reducing microorganisms to facilitate cellular respiration under anoxic conditions. In contrast, ferrous iron (Fe2+) is used as an electron donor by iron-oxidising microorganisms. The presence of dissimilatory pathways in iron metabolisers maintain bioavailable iron in the environment for other organisms. Redox reactions between gram-negative bacteria and iron usually occur through an extracellular electron transport (EET) pathway that allows electrons to cross from the inner membrane to the extracellular environment or vic

Abstract:

Nutrient pollution from industrial activity is an environmental problem that persists in water bodies near urban settings, and has been a primary contributor to eutrophication, bacterial contamination, and harmful algal blooms. Biogenic iron oxides offer a potential solution to the treatment of lakes and rivers containing high concentrations of phosphate, the limiting nutrient in aquatic systems. Soluble ferrous iron can act as an electron donor for iron-oxidizing bacteria, which thrive in low-oxygen environments. This results in the formation of insoluble ferric iron minerals, ideal ads

Despite being abundant in the earth's crust, the concentration of Fe in many oceanic regions is so low that it is limiting to the growth of photosynthetic plankton. Heterotrophic bacteria play key roles in the oceanic cycling of carbon and nutrients, but it is unclear whether they can be Fe-deficient in nature, or what possible effects Fe-deficiency might have on their ecology and physiology. In chapter 1, I investigated the response of a natural bacterial community to a mesoscale Fe-enrichment experiment in the northeast subarctic Pacific.

The microbial oxidation of minerals is a commercially important process. Until comparatively recently only one organism capable of mineral oxidation has been extensively studied - Thiobacillus ferrooxidans. Several new, potentially commercially important isolates were studied in comparison with T.ferrooxidans. This was done with regard to their iron and sulphur oxidation systems, which are vital to the process of mineral solubilisation, and their ability to solubilise the minerals pyrite or chalcopyrite. The study of the latter was undertaken with particular reference to mixed culture leaching

Abstract:

Bacterial infection is a leading cause of morbidity and mortality arising from platelet transfusions (1, 2). Storage of platelet products at room temperature (20 to 24ºC) provides ideal conditions for bacterial proliferation (1, 3-6). Furthermore, platelets are stored in plasma containing bioavailable iron that bacteria require to survive (7). Thus we hypothesize that the inclusion of iron chelators will bind and remove iron, thereby inhibiting bacterial growth in both culture medium and platelet concentrates. Additionally, we hypothesize that residual red blood cells (RBCs) in platelet units

Recent observations of initial stages of Pseudomonas aeriginosa biofilm formation on metal oxides surfaces indicate that siderophores may also facilitate bacterial adhesion to metals. However,

Abstract:

Iron corrosion is the most important economic and aesthetic problem facing utilities. In the water distribution system, problems caused by iron corrosion include "red water", scale buildup, and pipe failures. It is necessary to improve our mechanistic understanding of anaerobic iron corrosion in order to better address these concerns. Experiments were conducted to investigate the effect of soluble constituents (Fe2+, PO43-, and NH4+) on H2 evolution during anaerobic iron corrosion. At pH 7.0 when sulfide was absent, variable Fe2+ did not have much influence on H2 release rates, whereas

Abstract:

The resistance of Stenotrophomonas maltophilia to antimicrobial agents has become a major medical and public health problem. The frequent treatment of S. maltophilia borne infections with the same anti-microbial agent over a period of time inherently results in the pathogen developing resistance to the drug. A polyclonal antibody cocktail, D-Squared David L Scott 01 (D2-DLSO1) was used to recover surface exposed immunogenic polypeptides (SEIP’s) from the cell walls of S. maltophilia. Bioinformatics strategies (Blast analysis, sequence alignment hydrophilicity/hydrophobicity plots) were perform
