Rational:

The Plaque assay was checked for the presence of arthrobacter phage to determine whether a new soil sample will be collected.

Procedure:

• Cleaned lab desk with CiDecon and ethanol
• Checked the control for contamination and checked the plaque assay for plaque and contamination
• Cleaned lab desk with CiDecon and ethanol

Conclusion:

Both the control and plaque assay for soil E showed no signs of contamination. The plaque assay for soil E showed no signs of any plaque. For next lab I will collect a new soil sample, filter, enrich, and collect soil metadata on it.

Fig.8.E – This image shows the plaque assay for Soil E. The plate shows no signs of contamination or plaque.

Fig.9.E – This image shows the control plate for the plaque assay which shows no signs of contamination.
