by the emergence of Shiga toxin-producing Escherichia coli (Callaway et al.‚ 2013). Specifically‚ Shiga toxin-producing E. coli O157 is a foodborne pathogen of significant public health importance. It can cause mild to bloody diarrhea in humans which may progress to hemolytic uremic syndrome (Centers for Disease Control and Prevention‚ 1993; Hussein‚ 2007) that can be fatal in children‚ the elderly and immunocompromised individuals. E. coli O157 is also responsible for an estimated 63‚153 illnesses

price‚ and high degree of reduction have made glycerol a highly attractive and exploited carbon source for the production of fuels and reduced chemicals. Here we report the quantitative analysis of the fermentative metabolism of glycerol in Escherichia coli through the use of kinetic modeling and metabolic control analysis (MCA) to gain a better understanding of glycerol fermentation and identify key targets for genetic manipulation that could enhance product synthesis. The kinetics of glycerol fermentation

providers work more efficiently. One of these medical advancements would be a mutated E. coli. So how exactly can a mutated E. coli be an advancement? Well what scientist recently discovered is that this certain mutated bacteria actually will color urine to help diagnose medical diseases. So perhaps this mutated E. coli can make diagnosing certain issues a quicker process than before. One disease this E. coli mutant helps diagnose is diabetes. To elaborate on how this altered bacteria works

An Ode to E. Coli There is a natural human tendency to dismiss what we cannot see. This idea is based in evolutionary biology. Throughout most of human history‚ threats to our survival have been deadly predators . It is only natural then‚ that we should focus our concern on objects whose importance we can see. For this reason bacteria seem insignificant on the surface‚ its invisibility marking its lack of precedence as a threat. This is a misconception‚ because bacteria hold enormous power. It can

Research Question: E. coli strain MM294 is placed under different sound frequencies. Does sound frequency affect the growth of E. coli strain MM294? Background: Noise pollution is a problem in urban areas and can be the cause of several health issues and increase risks of disease. It is interesting that even something inanimate like sound could affect so much of biological processes. The movement of energy through matter produces sound. Sound is a mechanical wave that travels

examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved. Diffusion is the passage of solute molecules from an area of high concentration to an area of low concentration (Campbell & Reece‚ 2005). An example is ammonia diffusing throughout a room. A solute is one of two components in a chemical solution. The solute is the substance dissolved in the solution. The solvent‚ the other component‚ is any liquid in which the solute can be dissolved (Anderson‚ 2002)

Abstract:Conjugation is a natural occurring process that involves the transfer of DNA from one cell into another through a physical connection between the cells. In the following experiment‚ two strains of Escherichia coli bacterial cells (donor F’lac+strs and recipient F-lac-strr) underwent conjugation to produce a transconjugant strain (F’lac+strr). MAC plates and streptomycin were utilized to determine if conjugation had occurred. When plated‚ the donor colonies appeared red and the recipient

Student Lab Section 6 E. Coli Genetic Transformation with pGLO Plasmid Introduction: Genetic transformation is where one organism takes on a characteristic from another organism (Bacterial Transformation 2013). For this experiment we used the bacteria E. Coli to take in foreign jellyfish DNA which will allow it to change genetic material. This experiment determines the effects that the plasmid pGLO has in transferring the Green Florescent Protein found in a jellyfish into the bacteria. It

2015 Bacterial Transformation Lab Report Introduction In this lab‚ the goal was to transform the bacteria e-coli to glow in the dark (or under a black light). Four plates were set up with agar in them for the bacteria to feed on and grow. Changes were then made to the bacteria. One plate was the control plate‚ having only the LB or agar for the bacteria and negative pGLO‚ which is the liquid not containing the plasmid. This is the plate that was compared with the three others in order to identify
