Process for the fermentative preparation of L-threonine The invention provides a process for the fermentative preparation of L-threonine using Enterobacteriaceae which in particular already produce L-threonine and in which the nucleotide sequence(s) of coryneform bacteria which code(s) for the thrE gene are enhanced, in particular over-expressed.
发酵制备
L-苏氨酸的工艺 本发明提供了一种利用肠杆菌属(Enterobacteriaceae)发酵制备
L-苏氨酸的工艺,这种肠杆菌属尤其已经能生产
L-苏氨酸,而且其中编码 thrE
基因的子球菌核苷酸序列得到了增强,特别是过度表达。
