Microbes in Milk

The video tutorial explores bacterial growth in different types of milk: pasteurized, UHT, and powdered. Using a rezazurin indicator, the experiment measures bacterial activity by observing color changes in milk samples left unrefrigerated for three days. Pasteurized milk shows the most bacterial activity, UHT milk shows moderate activity, and powdered milk shows little to none. The experiment highlights how milk treatment affects bacterial growth, with implications for other pasteurized, UHT, and powdered products.
