Claims (3)
- 미생물의 발효에 의한 L-쓰레오닌의 생산에 있어서, L-시스테인을 요구하고 동시에 S-2-아미노에틸-L-시스테인(S-2-Amineothyl-L-cysteine)과 DL-아스파라긴산 하이드록사메이트(DL-Aspartate hydroxamate)에 내성을 갖는 쎄라티아(Serratia) 속 SW 9511(KFCC-10879)을 이용하여 L-쓰레오닌을 제조함을 특징으로 하는 발효에 의한 L-쓰레오닌의 제조방법.
- 제1항에 있어서, L-시스테인을 100∼500μg/ml 되게 첨가함을 특징을 하는 발효에 의한 L-쓰레오닌의 제조방법.
- 제1항 또는 제2항에 있어서, pH를 추가당과 암모니아를 이용 6.8∼7.2로 유지시키고, 당농도를 1% 미만으로 유지하면서 배양함을 특징으로 하는 발효에 의한 L-쓰레오닌의 제조방법.
