Abstract:

A number of freshwater isolates were used for this study. Strain S6l, a Gram negative adhesive bacterium, was isolated from a local freshwater source. Copious amounts of exopolysaccharide are produced during growth, and play a role in the adhesion process. Analysis of extracellular polymer synthesized by both S6l and other freshwater isolates, revealed that sugars found to occur most frequently were glucose, galactose and mannose; acetate and pyruvate content varied with strain. No unusual components were found in any of the preparations assayed. A new staining method was developed, allowing t

Les antibiotiques ont été utilisés pour le traitement des infections bactériennes depuis plus de 70 ans, sauvant des millions de vies. Cependant, leur mauvaise et sur-utilisation ont conduit à l’émergence de la résistance bactérienne. Outre le développement de nouvelles familles d'antibiotiques, la détection rapide et sensible de bactéries est très importante pour le diagnostic médical. Les polymères fluorescents représentent un grand potentiel, car ils sont faciles à fonctionnaliser, synthétiser et greffer. Les films sont plus pratiques, faciles à manipuler et peuvent être réutilisés, ce qui

In this thesis, I present three microscopy studies of surface growing Escherichia coli (E. coli ) microcolonies. All experiments were carried out by growing microcolonies on agarose pads, and imaging their growth using phase contrast, fluorescence and confocal microscopy.

An agarose pad was seeded with bacterial cells and their colonisation success tracked. Cell lag-times and local cell density were found to play important roles in determining the eventual succe

The ongoing interest in bacterial interactions with various surfaces, followed by attachment and subsequent biofilm formation, has been driven by the importance of bacterial activities in number of medical, industrial and technological applications. However, bacterial adhesion to surfaces has not been completely understood due to the complexity of parameters involved. The study presented herein investigates the attachment pattern of nine medically and environmentally significant bacteria belonging to different taxonomic lineages: Firmicutes - Bacillus, Gammaproteobacteria, Alphaproteobacteria

A and A- strains, (the latter isolated by growth at elevated temperature), were compared biochemically and their interactions with various cell types investigated. Strains of A. salmonicida possessing the A-layer were shown to be more hydrophobic than those dev

Abstract:

Soluble manganese (Mn) presents a significant treatment challenge to many water utilities, causing aesthetic and operational concerns. Surface water treatment plants using ozonation followed by biofiltration are unable to apply free chlorine across the filter, a method used by many utilities for soluble Mn control. These facilities are vulnerable to periodic problems of elevated Mn in the finished water. Manganese-oxidizing bacteria (MOB) readily oxidize Mn in groundwater treatment applications, which normally involve pH values above 7.0. However, the ability of MOB to facilitate Mn oxidation

Fecal bacteria and pathogens are a major source of surface water impairment. In Virginia alone, approximately 73% of impaired waters are impaired due to fecal coliforms (FC). Because bacteria are a significant cause of water body impairment and existing bacterial models are predominantly based upon laboratory-derived information, bacterial models are needed that describe bacterial die-off and transport processes under field conditions. Before these bacterial models can be developed, more field-derived information is needed regarding bacterial survival and transport. The objectives of this

It was found that duck meat extracts increased growth rate but did not alter the surface charge of the cells and when grown in minimal 010 and MCDB202 media the cells flocculated and showed

This study demonstrates that the surface motility of the bacterium Pseudomonas aeruginosa is dependent on the surface chemistry of the underlying substrate.

These results were obtained using time-lapse microscopy of bacteria exposed to continuously flowing tryptic soy broth growth medium at 37 ⁰C. Not only are the mean speeds different, the distributions of speeds are also different: on the hydrophobic substrate, a smaller proportion of bacteria move by less tha

Although various sea surface microlayer sampling techniques were developed over the past decades, aseptic bacterial sampling in the open ocean is a rather challenging task. In this

Abstract:

New methods and technology are needed to detect biological agents that threaten the health of humans and domestic animals. The bacterium Bacillus anthracis, causal agent of anthrax, has been used as a biological warfare agent. Here, we extend the work of Chinowksy et al. (2007) to the detection of a surrogate of B. anthracis, B. globigii (also known as B. atrophaeus, B. subtilis var. niger, B. subtilis var. subtilis) in a mixed sample containing two different species of Bacillus using a portable surface plasmon resonance (SPR) biosensor (SPIRIT 4.0, Seattle Sensor Systems). Two methods (direct
