Beschreibung
Zusammenfassung:	The present invention concerns a process for recovering fermentation products present in a fermentation mash produced in a bioreactor (9), comprising a step a) in which a gas stream (15) is sent into the fermentation mash under pressure in order to entrain at least a portion of the products and produce a gas stream (16) which is enriched in fermentation products. The process comprises a step h) for storage of the fermentation gases and the gas stream which is sent to the step a) is constituted by the stored fermentation gases.
