MUTANT YEAST STRAINS WITH ENHANCED PRODUCTION OF ERYTHRITOL OR ERYTHRULOSE

MUTANT YEAST STRAINS WITH ENHANCED PRODUCTION OF ERYTHRITOL OR ERYTHRULOSE

The invention relates to a method for enhancing the erythritol and/or erythrulose productivity and/or yield of an erythritol and/or erythrulose-producing yeast strain, such as Yarrowia lipolytica, comprising inhibiting in said yeast strain the expression or the activity of an endogenous L-erythrulos...

Beschreibung
Zusammenfassung:The invention relates to a method for enhancing the erythritol and/or erythrulose productivity and/or yield of an erythritol and/or erythrulose-producing yeast strain, such as Yarrowia lipolytica, comprising inhibiting in said yeast strain the expression or the activity of an endogenous L-erythrulose kinase and/or erythritol dehydrogenase. The invention also relates to a mutant yeast strain obtained by said method.
