  • Transformation Of Escherichia Coli With pGLO Plasmid

    Transformation Of Escherichia Coli With pGLO Plasmid April 24‚ 2013 ABSTRACT: This experiment focuses on genetic engineering and transformation of bacteria. The characteristics of bacteria are altered from an external source to allow them to express a new trait‚ in this case antibiotic resistance. In is experiment foreign DNA is inserted into Escherichia coli in order to alter its phenotype. The goal of the experiment is to transform E. coli with pGLO plasmid‚ which carries a gene for ampicillin

  • Conjugation and Transposition in Escherichia Coli

    Abstract The purpose of this experiment was to study the transfer of genetic information on plasmid F’lac by using Escherichia coli. Plasmid transfer was measured by using two different methods. The first one was by using selection and contraselection with three antibiotics: streptomycin(which was replaced by naladixic acid for the second part of the experiment)‚ampicillin and kanamycin and the second one by using a colour indicator ( X-gal). As significant results‚ the percentage of transfer for

  • Escherichia Coli Research Paper

    The Life of Escherichia Coli Escherichia Coli 0157:H7 bacterium can live in the intestines of cattle‚ therefore meat can become infected during slaughtering. You can contract this bacterium by eating undercooked meat‚ especially ground beef. Escherichia Coli 0157:H7 can also be contracted by eating contaminated fruits or vegetables‚ as well by drinking raw fruit juices or milk‚ or sewage contaminated water. Infection can also be spread via person to person. Escherichia Coli 0157:H7 can also

  • The Effects of Environmental Factors on the Absorbance of Escherichia Coli

    bacterium Escherichia coli is being subjected to various environmental factors that affect the rate of growth. These factors scrutinized were the different types of nutrients‚ the intensity of aeration‚ or the temperature at which it was stored. The purpose of this lab is to determine which factor affects the Escherichia coli the greatest. It is known that these abiotic factors affect the rate of growth the greatest if they remain at the correct conditions for living. Escherichia coli and other

  • Escherichia Coli and Staphylococcus Albus

    Escherichia coli and Staphylococcus albus Some bacteria’s require a certain amount of light in order to function properly and there fore survive. Escherichia coli is found in the gut and intestines of mammals. Staphylococcus albus is generally a skin dwelling bacteria Aim: To test whether the amount and type of light that the bacteria’s E.coli and S.albus are subject to causes changes in their growth rates and habits. To test whether the growth rates and habits of the bacteria’s E. coli

  • Escherichia Coli And Gram-Negative Bacterium Bacillus Cereus

    been considered one of the greatest newest innovations in medicine but there is still yet to be a perfect ideal antibiotic. In this experiment six antibiotics will be tested to determine which is the most effective on gram-negative bacterium Escherichia Coli and gram-positive bacterium Bacillus Cereus. In previous class experiments‚ gram-staining was conducted to determine the qualities of gram-positive

  • Hand Soap Effectiveness On Escherichia Coli

    Hand Soap Effectiveness on Escherichia Coli Abstract: Bacteria are an essential part of many different living organisms and ecosystems across the globe. Without bacteria there would have never had been life in the first place. But some bacteria have evolved to cause to humans‚ resulting in the need to eliminate them through such methods as soap. Hand soap is a crucial part of human health‚ especially in such places as schools and hospitals. In this experiment I wanted to determine the effectiveness

  • Microbiology lab report on Escherichia coli and Staphylococcus aureus.

    experiment two different types of bacteria‚ Escherichia coli and Staphylococcus aureus‚ were grown singly and mixed on four different types of agar in order to observe the varying morphologies within the colonies. Resulting data was analyzed to provide understanding of the use of differing culture media and conditions for bacterial growth. RESULTSFour different agar types were used in this experiment. The first (Nutrient) allowed for growth of both E. coli and S. aureus. The second agar used (MKL)
