The manner which produces L amino acid making use of the korinebakuteriumu being attached strain, and the said strain where the hurukutokinaze gene which is derived from the eshierikia being attached strain is introduced.

摘要

As for this invention, the hurukutokinaze gene which is derived from the eshierikia being attached strain is introduced, although fructose is made to convert to fructose 6 phosphoric acid, in order for it to be possible to prevent the consumption of unnecessary energy, due to the fact that hurukutokinaze which can show sufficient activity is revealed, regards the manner which produces L amino acid character making use of the korinebakuteriumu being attached strain and the aforementioned strain which are converted. Character of this invention as for the korinebakuteriumu being attached strain which is converted, by the fact that consumption of unnecessary energy when being renewed of fructose is prevented with hurukutokinaze which is revealed from the hurukutokinaze gene of eshierikia origin, compared to it is possible to produce L amino acid economically. Therefore, it is possible to utilize widely in effective production of L amino acid. Choice figure Drawing 1
