Hello everyone. So this week I spent most of my time working
on my unknown bacterial identification project. Trying to keep thorough notes throughout
the process has been a not so fun, but necessary challenge. I observed and
recorded my bacterial colony morphology, performed a gram stain, and looked at
my bacteria under the microscope to describe and record the cell morphology.
Then according to the dichotomous key, I did an oxidase test, glucose
fermentation, and a SIM test. I have
officially identified my bacteria to be E.
Coli. I also helped Luis get caught up and showed him how to do a streak
plate and explained the process of gram staining since he has never taken
microbiology. So it was nice to make a new friend in the process and be able to
help someone else out. Below are images of my glucose fermentation results as
well as my SIM test after 24 hours of incubation.
