Summary:

Floculalion in Sacch. cerevisiae is a process of reversible cellular aggregation. Their ability to flocculate enables efficient separation of cells from the fermentation medium and facilitates subsequent downstream processing of the product. The most important advances in our knowledge have been achieved about the mechanisms of flocculalion and its genetic bases. Recent advances in both fields are reviewed and some possible hints for the future are given.
