Title (EN) ETHANOL PRODUCTION BY $i(ZYMOMONAS) CULTURED IN YEAST-CONDITIONED MEDIA
(FR) PRODUCTION D'ETHANOL PAR DES $i(ZYMOMONAS) CULTIVEES DANS DES MILIEUX CONDITIONNES PAR DES LEVURES
Abstract:
(EN) A process for producing ethanol in the substantial absence of fusel oils by $i(Zymomonas) fermentation wherein fermentation is carried out under conditions unfavorable for the growth and replication of yeast. In the preferred embodiment, $i(Zymomonas) are initially inoculated into a carbohydrate containing medium undergoing active fermentation by yeast, then the fermentation conditions altered to inhibit growth and replication of yeast.
(FR) Selon un procédé de production d'éthanol en l'absence d'huiles de fusel par fermentation par $i(Zymomonas), la fermentation est mise en ÷uvre dans des conditiions défavorables pour la croissance et la reproduction des levures. Dans le mode préférentiel de réalisation, on inocule initialement les $i(zymomonas) dans un milieu contenant des hydrates de carbone en fermentation active par des levures, puis on modifie les conditions de fermentation afin d'inhiber la croissance et la réplication des levures.
