Dear Blog and Blog Readers,
Woohoo! We finally determined what type of bacteria we have! It's called "Serratia marcescens." What finally gave its true identity away is the red pigment. And due to the fact that none of the other types of bacteria are red . . . we could have identified our bacteria right away! Unfortunately though, we didn't know this until the end.
Here, we are examining a bacteria sample that has conveniently decided to reside on the cabinet door! We examined its many features in order to determine its true identity.
Today, we also made yogurt in class. We did this by placing a little bit of yogurt in milk. We then allowed the milk to sit as the enzymes in the yogurt converted the rest of the milk into more, and more yogurt. However, this is only done with greek yogurt.

Sample #1
Sample #2
The only antibiotic our bacteria was resisted by was neomycin, and aminoglycoside. Interestingly enough, erythromycin inhibited the pigment in our bacteria but not the bacterial growth itself.
