Nose Goes

The first thing we did today was get our bacteria that we had swabbed from our nose. We looked at it under the light, it was pretty gross! 

After we spent some time looking at our bacteria, we did some disinfecting tests. The first thing we did was swab our classmate's cell phone and inoculated it in a nutrient agar plate.

We then took samples of different disinfectants and placed it on our new sample to see if it would grow. We used a bunsen burner to sterilize our forceps each time we obtained a new disinfectant.

We divided our nutrient agar into four quadrants and placed a different type of disinfectant in each one. 

Our disinfectants were tooth paste, mouthwash, bleach, and hand sanitizer. We incubated our sample at room temperature (25*C)

 After that we made a streak plate of our unknown bacteria. We are testing to determine if it is an obligate anaerobe bacteria. We took the bacteria to an anaerobic chamber. We incubated the chamber at 37*

We all then took a sample of bacteria that we had obtained over the semester, and placed them in a beaker of water. The idea behind this was to mirror a pond or body of water that has a lot of bacteria in it. Our goal was to make this water drinkable. We did this by using UV light to purify the water.

We started this experiment with Juliette swabbing a sample of the bacteria water on an agar plate. We then used a UV light to kill the bacteria. 

After this Juliette swabbed the water once again on an agar plate to test and see if the water had been successfully purified. We then treated the water with UV light and took another sample of the water. 

We put the plates in the incubator. We'll see what grows by Thursday!
