Biofilm formation of environmental and enterohemorrhagic Escherichia coli / by Stefan Moreira.
(2010)Sample sites : Boulevard Lake & Chippewa Park, Thunder Bay ; Billy Lake, Dorion (Northwestern Ontario). -
Developing a Multiplex PCR Platform to Determine the Virulence Genes of Escherichia Coli in Boulevard Lake, Thunder Bay, Ontario
Given the evidence that E. coli can establish in the periphytic community and be released back into the water column, it is important to understand the pathogenicity of this group of E. coli by examining the virulence genes ... -
Development of bacterial systems for the production of cellulase and bioethanol
(2013-02-01)The wide varieties of extant bacterial species are often resistant to various environmental stresses. This demonstrates their frequent ability to adapt to and thrive in challenging environments. One such adaptation in ... -
Ecology of pathogenic Escherichia coli in water : survival and molecular detection
(2003)Recently there has been a surge of interest in the ability of enterohemmorhagic Escherichia coli (EHEC) to survive in aquatic environments. It has been speculated a correlation may exist between the genotype of an E. ... -
Effect of biofilm and the role of rpoS on the survival of a p-Nitrophenol-degrading Pseudomonas putida / by Miranda Maki.
(2008)Pseudomonas putida is a Gram negative bacterium that can be found naturally in the environment as planktonic free-living cells, or in concert with other bacterial species in biofilms. In this study, the P. putida strain ... -
Effect of carbon-starvation on the survival of and PNP degradation by a Moraxella strain
(2004)The effect of carbon-starvation on the stress resistance responses of a p-nitrophenol degrading Moraxella strain was examined in both, buffer and river water samples. The Moraxella strain showed optimal stress resistance ... -
Effect of periphytic Escherichia coli and lake water bacterial population on the biofilm establishment of a Shiga toxin producing Escherichia coli O157:H7 strain
(2015)Biofilm studies Escherichia coli (E. coli) have typically focused on 0157:H7 in defined, laboratory medium. While there is value in such studies, they offer little in the way of explaining the behaviour and interactions ... -
Effect of rpoS inactivation on biofilm formation of a p-nitrophenol degrading Pseudomonas putida strain
(2005)With the widespread existence of environmental pollutants in the modern world, effective, non-destructive means of remediation are becoming more and more desirable as an alternative to the traditional excavation and ... -
Effects of ultra violet and visible light on bacterial survival / by Natasha Vermeulen.
(2006)The optical dose in mJ/cm[superscript]2 for causing mortality of Escherichia coli, using wavelengths between 230-375 nm in the UV and 400-532 nm in the mid-visible spectral regions, has been determined in this study. ... -
Freeze-thaw effect on selected fecal indicator bacteria : Escherichia coli and Enterococcus faecalis / by Nicole A. Hawdon.
(2008)The survival of two selected fecal indicator organisms, two strains of Escherichia coli, a Gram-negative bacterium, and two strains of Enterococcus faecalis, a Gram-positive bacterium, after freezing and thawing successively ... -
Membrane fouling and its control in drinking water membrane filtration process
(2014-01-22)Treatment of surface water in the presence of natural organic matters (NOM) becomes a challenging issue to meet stringent rules of Safe Drinking Water Act (SDWA). Ultrafiltration (UF) membrane is emerging as an efficient ... -
Modeling the transport of Escherichia coli through the subsurface environment
(2009)Subsurface microbial transport is an important concern in many engineering projects. Expanding the knowledge of this process is important for the risk assessment of sites capable of releasing pathogenic bacterial species ... -
Molecular analysis of bacterial diversity on central venous catheters recovered from cancer patients
(2005)Central venous catheters (CVC) are a known source of nosocomial blood stream infections. However, standard cultivation methods to identify causal pathogens of catheter-related blood stream infections (CRBSI) on catheters ... -
One-step inactivation of rpoS to investigate its role on Escherichia coli O157:H7 biofilm formation and survival
(2009)Homologous linear recombination using the recombinogenic capabilites of phage red genes exo, bet and gam, has been used increasingly to generate targeted gene replacements in Gram-negative bacteria. -
Submerged anaerobic membrane bioreactors for wastewater treatment and membrane fouling characterization and control
(2012-11-10)This thesis focused on effects of transient conditions (pH shocks, temperature variation and temperature shocks) on the performance and membrane fouling characterization and control of submerged anaerobic membrane ... -
Transport of Escherichia coli through soil / by Bruce Rosa.
(2007)Sorption is an important process in the retention of pathogens by clay barriers. Batch sorption experiments were conducted to investigate the sorption of nonpathogenic 'E. coli' to illite, kaolinite, and montmorillonite ...
