STEP 5: Identifying Yeast - Microscopy

Summer 2018:

Here are pictures of your samples as seen through a microscope at 400x magnification. Microscopy allows us to look closer at the cells growing on the Agar plates so that we can confirm that they are yeasts.  Compare the cells in your image with the image at the right which shows yeast cells zoomed in 400x. Click the link to learn more about the science behind this step of the Yeasty Beasties process.
