Claims (6)

페니실린계 항생제 및 계면활성제에 대한 감수성이 높고 글루타민산을 탄소원 및 질소원으로 자화할 수 없으며 비오틴 과잉존재하에서도 글루타민산을 생산하는 브레비박테리움 락토피멘텀의 변이주인 미생물(KFCC 10662).Microorganisms (KFCC 10662), which are highly susceptible to penicillin antibiotics and surfactants, cannot magnetize glutamic acid to carbon and nitrogen sources, and produce glutamic acid even in the presence of excess biotin (KFCC 10662). 제1항에 있어서, 배양초기 내지 말기 또는 정지기에 페니실린계 항생제 또는 계면활성제를 비오틴 과잉배지에 첨가하지 않아도 글루타민산을 생산하는 미생물.The microorganism according to claim 1, wherein glutamic acid is produced without adding penicillin antibiotic or surfactant to the biotin excess medium at the beginning to the end of the culture or at the end of the culture. 제1항에 있어서, 글루타민산을 탄소원, 질소원이나 에너지원으로 사용할 수 없는 미생물.The microorganism according to claim 1, wherein glutamic acid cannot be used as a carbon source, a nitrogen source, or an energy source. 제1항에 있어서, 페니실린농도가 0.03u/ml 이상인 조건하에서는 생육할 수 없는 미생물.The microorganism according to claim 1, wherein the microorganism cannot grow under a condition where the penicillin concentration is 0.03 u / ml or more. 제1항에 있어서, 비이온계 계면활성제인 트윈 40의 농도가 50㎍/ml이상인 조건하에서 생육할 수 없는 미생물.The microorganism according to claim 1, wherein the microorganism cannot grow under the condition that the concentration of Tween 40, which is a nonionic surfactant, is 50 µg / ml or more. 브레비박테리움 락토퍼멘텀의 변이주인 KFCC 10662를 폐당밀, 포도당, 전분 가수분해물 및 원당등이 포함된 배지중에서 배양하여 배양물로부터 글루타민산을 채취하는 것을 특징으로 하는 미생물을 이용한 글루타민산의 제조방법.A method for producing glutamic acid using microorganisms, comprising culturing KFCC 10662, a variant of Brevibacterium lactofermentum, in a medium containing waste molasses, glucose, starch hydrolyzate, and raw sugar, to obtain glutamic acid from the culture. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
