When we've done this in the past, I just put a bunch of yeast in water, added Congo red until the solution was quite red, then boiled it for a couple of minutes, maybe five minutes. I've just used baker's yeast from the grocery store. If you're adept with the microscope, you can measure everything while alive. If not, just put a little drop of 10% formalin at the cover glass edge to slow stuff down.

How difficult is this experiment, I am conducting a similar experiment (using blue litmus dye as an alternative to Congo red). Also what did you do to prepare the yeast and what was the substance used Ronald their movement (molarity if possible) thank you
