| description | Est décrit un procédé perfectionné de fermentation pour produire des acides carboxyliques. Le perfectionnement consiste à cultiver des champignons de l'espèce Rhizopus dans un milieu de culture renfermant une source de carbone, une source d'azote et des sels inorganiques, dans des conditions d'apport modulé d'oxygène. La concentration en oxygène dissous pour la phase de croissance cellulaire se situe entre 80 et 100 % et la concentration en oxygène dissous pour la phase de production d'acide se situe entre 30 et 80 %.
An improved fermentation process for producing carboxylic acids is disclosed. The improvement comprises growing fungi of the genus Rhizopus in a culture medium containing a carbon source, a nitrogen source and inorganic salts, under conditions of controlled oxygen availability wherein the dissolved oxygen concentration for the cell growth phase is between 80% and 100% and where the dissolved oxygen concentration for the acid production phase is between 30% and 80%. |
