액체배양에 의한 Monascus rubber의 적색 색소 생산을 위한 최적 배양 조건에 관한 연구 = Studies on the Optimal Culture Condition for Production of Red Pigments by Monascus rubber on Liquid Culture

국문 초록 (Abstract)

Monascus rubber KCTC 6122를 이용하여 액체 배양을 통한 실험균의 적색 색소의 생산을 위한 배양 조건의 최적화에 관한 결과는 다음과 같다. 실험 균주가 생산하는 적색 색소의 최적 배양 조건은 탄소원으로 rice powder 4% 첨가, 질소원으로 NaNO₃ 0.2%, 인산염으로 Na₂HPO₄의 농도가 0.3%, MgSO₄의 농도가 0.15%일 때 가장 높은 적색 색소 생성을 나타내었다. 배양 온도는 30℃, 초기 pH가 6.5, 진탕속도를 150 rpm, 배양 시간 8일 일 때 적색 색소의 생성능이 흡광도 70.29로 가장 우수하였다.

The optimum cultural conditions for production of red pigment from Monascus rubber KCTC 6122 is liquid culture were studied. Monascus rubber KCTC 6122 was shown to give the maximum production of red pigment in the medium containing 4% rice powder, 0.2% NaNO₃, 03% NaHPO₄and 0.15% MgSO₄. The optimum culture conditions, temperature, initial pH and shaking speed were 30℃, 6.5 and 150 rpm, respectively. The red pigment production reached a maximum level at 8days of cultivation.
