Title (EN) ACETIC ACID CONSUMING STRAIN
(FR) SOUCHE CONSOMMATRICE D'ACIDE ACÉTIQUE
Abstract:
(EN) The invention describes a process for the production of ethanol from a composition comprising glucose and between 50 μM and 100 mM acetic acid, said process comprising fermenting said composition in the presence of a recombinant yeast which is capable to convert acetic acid anaerobically; maintaining the amount of undissociated acetic acid at a value of at least 50 μM; and recovering the ethanol. Said process is useful for both starch and cellulosic based, acetic acid containing hydrolysates and advantageously results in a greater consumption of acetic acid and thus higher ethanol yields.
(FR) L'invention concerne un procédé de production d'éthanol à partir d'une composition comprenant du glucose et entre 50 μΜ et 100 mM d'acide acétique, ledit procédé comprenant la fermentation de ladite composition en présence d'une levure recombinante qui est en mesure de convertir l'acide acétique de manière anaérobie ; le maintien de la quantité d'acide acétique non dissocié à une valeur d'au moins 50 μΜ ; et la récupération de l'éthanol. Ledit procédé est utile pour des hydrolysats à la fois à base d'amidon et à base de cellulose, contenant de l'acide acétique, et entraîne avantageusement une plus grande consommation d'acide acétique et donc des rendements supérieurs en éthanol.
