The number of yeast cells in a growing population is recorded at short time intervals by automatic optical density OD reading in a microplate-spectrophotometer and the relevant variables. Optical density or absorbance is the logarithmic ratio of the intensity of light entering the yeast cell suspension to the intensity passing through it.
