Abstract
Ninty four strains of lysine producing micro-organisms in culture broth during fermentation have been isolated from soil and other sources. From the comparison of the amounts of lysine produced, 6 strains have been selected as the potentially useful strains, and identified tentatively as Micrococcus sp. (S-16-4), Corynebactcrium sp. (S-27-12, S-281-3, CBY-4) and Brevibacterium sp. (M-6-71, F-629-2), respectively. From the further studies with Corynebacterium sp., S-27-12, its maximum yield was found to be 4mg lysine/ml of synthetic medium, consist of glucose(7.5%), urea(0.6%),
전국 각지에서 수집한 토양을 비롯한 기타 시료로부터 배양액중에 lysine을 생산 축적하는 미생물 94주를 분리하여 이를 다시 비교 검토함으로써 lysine생산이 2 mg/ml 이상인 균주 6주를 선정하고 균학적 성질을 조사한 결과 Micrococcus 속 1주, Corynebacterium 속 3주, Brevibacterium 속 2주였다. Corynebacterium sp. 1주 (S-27-12)에 대한 합성 배지에서의 lysine 축적조건을 검토한 결과 glucose 7.5%, urea 0.6%,
