When exponentially growing cells of bottom‐fermenting yeast were starved for nitrogen or were grown on proline (a non‐preferred nitrogen source), flocculation was induced. This flocculation was not induced by starvation for either carbon or amino acids. Expression of Lg‐ FLO1 , which is required for flocculation of bottom‐fermenting yeast, was also found to be induced by starvation for nitrogen. This suggests that the flocculation of bottom‐fermenting yeast is under the control of a nitrogen catabolite repression (NCR)‐like mechanism. Copyright © 2012 John Wiley & Sons, Ltd.
