Document Summary

This experiment was carried out to successfully decontaminate a water sample that was infected with escherichia coli. The purpose was to decontaminate the escherichia coli from the water sample using an antibacterial agent as well as to test for the presence of the lac z gene in. The testing for the presence of escherichia coli strains was done using a variety of microbiological techniques including aseptic techniques, serial dilutions and plating techniques. In the first part of the experiment, the contaminated water sample was treated with salt water. The salt water acted as a decontaminating agent, and this allowed the ability to assess its productivity in killing the escherichia coli bacteria. There were two components used: a control plate (which did not include the salt water sample) and a treatment plate (which included. The control plate and the treatment plate were prepared through a series of.
