MALONIC SEMI-ALDEHYDE-PRODUCING YEASTS

The present invention relates to a recombinant yeast, in the genome of which at least one nucleic acid encoding an enzyme able to catalyze the decarboxylation of oxaloacetate into malonic semi-aldehyde, or one of its salts is overexpressed and/or under the control of a strong or inducible promoter....

Beschreibung
Zusammenfassung:	The present invention relates to a recombinant yeast, in the genome of which at least one nucleic acid encoding an enzyme able to catalyze the decarboxylation of oxaloacetate into malonic semi-aldehyde, or one of its salts is overexpressed and/or under the control of a strong or inducible promoter. The invention also relates to such an enzyme per se, as well as to a method for producing malonic semi-aldehyde, one of its salts, or a malonic semi-aldehyde derivative comprising implementing the said recombinant yeast and to the use of the said recombinant yeast for the production of malonic semi-aldehyde, one of its salts, or a malonic semi-aldehyde derivative.
