Fermentation system in which the product is continuously removed by extraction with a solvent that is insoluble in water, not harmful to the organism, simple to recover (e.g., by distillation) and in which the fermentation product is considerably more soluble than it is in water. The fermenter may be fed nutrient continuously or intermittently. 1, record 1, English, - extractive%20fermentation
Record number: 1, Textual support number: 1 OBS
One advantage of this type of reactor is that products may be removed before they reach concentrations that limit the rate of fermentation by feedback inhibition. The disadvantage is that few, if any, solvents with the required properties have been identified. 1, record 1, English, - extractive%20fermentation

Procédé de fermentation au cours de laquelle il y a production et extraction simultanées du produit.

En plus des [...] principaux types de bioréacteurs, il convient de signaler la mise au point des bioréacteurs spéciaux dans le but d'améliorer les capacités de transfert d'oxygène tout en réduisant la consommation d'énergie : [...] des bioréacteurs «pulsés», mécaniquement et pneumatiquement, adaptés des techniques d'extraction liquide - liquide, aux performances intéressantes en production de biomasse. Appliqués à la fermentation alcoolique, ils permettent de réaliser une fermentation extractive à l'aide d'un tiers solvant, le dodecanol, qui extrait l'éthanol, inhibiteur des cellules, au fur et à mesure de sa production. 3, record 1, French, - fermentation%20extractive
