Title
Verfahren und Vorrichtung zur Herstellung von Essigsaeure
Other Title
Fermentation device for the production of a fermentation product from cells in a medium, preferably acetic acid, lactic acid and propionic acid, comprises a filter unit contained within a bioreactor.
Abstract
Die Erfindung betrifft eine Vorrichtung zur Gewinnung eines Fermentationsproduktes wie Essigsaeure, umfassend einen Bioreaktor und eine innerhalb des Bioreaktors angeordnete Filtrationsvorrichtung, so dass waehrend des laufenden Betriebes die zur Fermentation verwendeten Zellen im Bioreaktor von dem produkthaltigen Medium mittels Filtration abgetrennt und das filtrierte, von Zellen befreite produkthaltige Medium anschliessend aus dem Bioreaktor heraustransportiert werden kann, sowie ein Verfahren zur Filtration des zell- und produkthaltigen Mediums innerhalb des Bioreaktors.
