본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

Claims (2)

L-라이신 생성능을 보유하는 미생물 코린박테리움 스피시즈(Corynebacterium Species) TR-3579(KFCC-10065)에 의한 L-라이신의 연속발효를 행함에 있어 주발효관 배양액중의 PO4이온 농도를 280PPM 이상의 고농도로 유지되도록 추가 배지 및 PO4이온 용액을 연속 추가시키는 연속발효를 행하여 배양액중에 L-라이신을 생성 축적시켜 배양물로 부터 L-라이신을 회수함을 특징으로하는 연속 발효 방법에 의한 L-라이신 생산방법.In the continuous fermentation of L-lysine by microbial Corynebacterium Species TR-3579 (KFCC-10065) having the ability to produce L-lysine, the concentration of PO 4 ion in the main fermentation broth culture was higher than 280 PPM. L-lysine production by a continuous fermentation method characterized by recovering L-lysine from the culture by performing continuous fermentation by continuously adding additional medium and a PO 4 ion solution so as to maintain the L-lysine in the culture medium. Way. 제1항에 있어서 주발효관에서 부발효관으로 이송되는 배양액의 연속발효에서 PH를 6.2±0.1로 전이하고, 배양시간을 6시간으로 함을 특징으로 하는 2단 연속 발효방법에 의한 L-라이신 생산방법.The L-lysine according to the two-stage continuous fermentation method according to claim 1, wherein in the continuous fermentation of the culture solution transferred from the main fermentation tube to the side fermentation tube, the pH is transferred to 6.2 ± 0.1 and the incubation time is 6 hours. Production method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
