Hi! This is my first week with TRAIN. This week has been unexpectedly overwhelming. I'm not going to lie I really didn't like it. However today is the first time since I've been at PC that I've gotten to work a compound microscope. I was really excited and enjoyed it so much. I also got to see the internship space for the first time which made me anxious. I'm sure the anxiety will settle and I'll gain my footing soon. I think I'm interested in the E.coli and aloe Vera experiment and have started doing as much research on the topic. Aside from that spring break is next week and my birthday. I'd loved to say that I'll actually be taking a break but I'll most likely be working and watching lecture videos.
On Tuesday, I plated E. Coli and tested the effectiveness of 4 samples to kill the bacteria. The sample included , Aloe Vera gel (store bought), Windex, Tap water, and 70% Isopropyl Alcohol. This experiment was pretty much used to keep me busy as I haven't yet been able to start a project. However when I came in Wednesday, I found some interesting results. The zone of inhibition was basically 0 for every sample, including the isopropyl alcohol. Although the tap water, being the control, and the Windex doesn't jump out as a surprise to me, the 70% Alcohol does. Originally I had two hypothesis's on why this occurred. One being that because E. Coli is a gut bacteria and therefore is built to withstand alcohol. The second theory suggest user error such as the letting the alcohol evaporate to much before I was able to put the disk on the plate. Because of the results on Wednesday and with the first hypothesis in mind, I chose to do another plate instead with Staphylococcus. I ch...
