Rational:

To check and see if the plaque assay has any plaques and to comfirm the results from the spot test.

Procedure:

• Took the plaque assay and control plates out of the incubator at 2:30 (46.5 hrs in the incubator)
• Observed no contamination on the control plate for group 2
• The arthrobacter lawn looked rough, but there was no signs of a plaque

Future Steps:

By next lab I will get a new soil sample. Recording pictures, data, and observations about the tree that the soil sample was taken from. On Wednesday I will filter the soil sample to prepare for  new spot test and plaque assay.

Fig.8 – The plaque assay had a grainy texture, but no signs of a plaque were seen

*Note the soil sample was not collected on 9/5, but on 9/7. Also the filtration was not done on 9/5.
