Bacteria Lab Observations

Bacteria Lab Observations
----Group Member: Ashley Zheng, Nancy Yu, William Lin

1st plate: Aseptic (plain)
2nd plate: Aseptic (controlled)
3rd plate: Unknown

First Observation
-Our first plate was contaminated. We found a huge round colony of mold inside it. We supposed maybe it was contaminated because the cap of the plate was not closed well enough.
-The experiment for the second plate had not started yet.
-The third plate did not have anything in it. The reason might be the bacteria had not started growing or no bacteria were captured.

Second Observation
-The contaminated plate grew a small white colony and two yellow colonies, one big and one small.
-The second plate was still empty; maybe the growth had not started.
-The third plate grew a huge yellow colony and 3 small white colonies in area B which is the area for switch. Also, there were a red colony and a clash of white colonies in area C which is the area for door knob.

Final Observation
-The contaminated plate grew a new red colony and a new yellow colony.

-There were 2 huge white colonies growing in the second plate in the area F. Nothing was growing around the soaped and Lysol paper scrap. Also, many orange colonies were growing in area H and G. Some bacteria were growing around the indisposed paper scrap.
-The third plate remained almost unchanged except the colonies were a little bigger.

Since we discussed together for the observations, our group members may have similar observations.
