Beschreibung
Zusammenfassung:The present invention relates to the use of at least one inorganic nitrate in a fermentation process for producing erythritol using a yeast strain of the Moniliella species as an erythritol-producing microorganism, characterized in that the at least one inorganic nitrate is simultaneously used as a main nitrogen source and as a pH regulator in the culture medium, as well as to such an improved method for producing erythritol. La présente invention concerne l'utilisation d'au moins un nitrate inorganique dans un procédé de fermentation pour la production d'érythritol, lequel procédé utilise une souche de levure de l'espèce Moniliella en tant que micro-organisme produisant de l'érythritol, caractérisée en ce que ledit ou lesdits nitrates inorganiques servent en même temps de source principale d'azote et de régulateur du pH du milieu de culture. L'invention concerne en outre un tel procédé amélioré pour la production d'érythritol.
