L-threonine Overproducing Microorganism Which Constructed by Specific Genetic Modifications and Method for Preparing L-threonine Using the Same부위특이적 변이에 의해 제조된 고수율의 L-쓰레오닌 생산균주 및 이를 이용한 L-쓰레오닌의 제조방법
The present invention relates to a mutant microorganism producing a high concentration of L-threonine in high yield, prepared using site-specific mutation, not random mutation, such as treatment with a mutation inducer, a method for preparing the same, and a method for preparing L-threonine using the mutant microorganism producing L-threonine. By using the mutant microorganism according to the present invention, L-threonine can be prepared at high yield, additional strain development becomes possible and their physiological phenomena can be easily understood since genetic information of L-threonine producing microorganism can be identified.
