A chemostat study was performed with yeast. The medium flow rate was varied and the steady-state concentration of cells and glucose in the fermenter were measured and recorded. The inlet concentration of glucose was set at 100 g/t. The volume of the fermenter contents was 500 ml. The inlet stream was sterile.
