Dear Blog and Blog Readers,
Today in microbiology we checked the agar plate we infected with bacteria from the sink handle to see which disinfectant inhibited the bacteria growth.
However, as seen on this plate, the bacteria did not grow at all. Therefore, we decided to test a new area. This time, I took a swab from the bathroom sink handle assuming that those handles are cleaned less than those in the lab.
Here is the new plate:
We placed this in the 25 degree Celsius incubator (room temperature and will check it next class.)
Next we took plates out of the an-ox tank they were in to see if lack of oxygen inhibited bacteria growth.
The bacteria still grew in this environment. Therefore it can be concluded that our bacteria is facultative aerobe because it did not thrive but it survived.
Next, we began to fill out a sheet summarizing all the tests we have done to determine the bacteria we have, but did not find the answer just yet...read the next few posts to find out!
