Beschreibung
Zusammenfassung:	The present invention provides an improved biotechnological production of riboflavin (also referred herein as vitamin B2) using genetically engineered microorganisms, in particular microorganism selected from Bacillus, such as e.g. Bacillus subtilis. Using said modified microorganisms, the yield of riboflavin 5 production could be increased by at least 5%. The present invention relates to modified microorganisms, processes to generate said modified microorganisms and the use thereof for production of riboflavin. La présente invention concerne une production biotechnologique améliorée de riboflavine (également appelée ici vitamine B2) utilisant des micro-organismes génétiquement modifiés, en particulier des micro-organismes choisis parmi Bacillus, par ex. Bacillus subtilis. L'utilisation desdits micro-organismes modifiés permet l'augmentation du rendement de production de la riboflavine 5 d'au moins 5 %. La présente invention concerne des micro-organismes modifiés, des procédés de production desdits micro-organismes modifiés et leur utilisation pour la production de riboflavine.
