    Abstract: The present invention relates to a method for producing highly-concentrated L-amino acid and riboflavin simultaneously, and a microorganism for simultaneously producing L-amino acid and riboflavin. Specifically, the present invention relates to a modified microorganism for producing L-lysine or L-threonine, and riboflavin simultaneously, wherein the microorganism belonging to Corynebacterium sp. capable of producing L-lysine or L-threonine is modified by enhancing the activity of an enzyme family expressed by a rib operon which contains riboflavin biosynthesis gene family. Also, the present invention relates to a method for the simultaneous production of L-lysine or L-threonine, and riboflavin using the modified microorganism, and relates to a formulation or granular formulation, feed, and feed additive, containing L-lysine or L-threonine, and riboflavin produced from a culture medium of the modified microorganism.

    Abstract translation: 本发明涉及同时生产高浓度L-氨基酸和核黄素的方法,以及同时生产L-氨基酸和核黄素的微生物。 具体地说,本发明涉及同时生产L-赖氨酸或L-苏氨酸和核黄素的改良微生物,其中属于棒状杆菌属(Corynebacterium sp。)的微生物。 能够通过增强由含有核黄素生物合成基因家族的rib操纵子表达的酶家族的活性来修饰能够产生L-赖氨酸或L-苏氨酸的能力。 此外,本发明涉及使用该修饰微生物同时生产L-赖氨酸或L-苏氨酸和核黄素的方法,涉及含有L-赖氨酸或L的制剂或颗粒制剂,饲料和饲料添加剂 - 苏氨酸和由修饰微生物的培养基产生的核黄素。
