Today, we prepared yogurt as a class using Vitamin D milk, Kefir, and Mrs. Pathakamuri's homemade probiotic tablet yogurt! First, we microwaved the milk and let it cool to 37 degrees Celsius. Then we poured the milk into three different labeled cups, Kefir, Yogurt, and Control. We added about a teaspoon of Kefir and yogurt to their respective cups, then covered and put the cups in the incubator at 37 degrees. Tomorrow, the cups will be moved to the fridge and Thursday, WE EAT! We also prepared smear plates of our unknown bacteria and subjected half of the plate to long-wave UV-C light for 30 seconds. After that, we inoculated a beaker of water with unknown bacteria and sterilized it with Dr. Pathakamuri's UV SteriPEN! Today's lab had really practical applications to the real world, I'm so excited to learn more about microbiology and pathophysiology next semester.
