Yeast (nerd warning)

Today I counted how many cells I have in my starters. As expected, the stir plate starter has about twice as many cells as the simple starter. As we also have a very nice microscope at work, I even took a 63x magnified picture of my Wyeast 3944 culture.
You can see 3 budding yeast cells. The mother cells are fully equiped with the vacuole clearly visible. The black and white spots are granules, the white ones being fat granules and the black ones glycogen granules. The white "moon" next to the vacuole is the nucleus of the cell.
