Abstract

The optimum cultural conditions for production of Monascus natural pigment by Monascus purpureus MK2 were investigated in submerged culture. This strain was showed the maximum production of monascus natural pigment in the optimal medium of 3.0% wheat flour, 0.15% $NaNO_3$, 0.2% $K_{2}HPO_4$ and 0.05% $MgSO_4{\cdot}7H_{2}O$, at pH 7.0. The maximum production of this pigment was achieved at $30^{\circ}C$ for 7 day cultivation under 130 rpm shaking. At optimal condition, Monascus purpureus MK2 produced 29.10, 36.84 and 48.92 units of yellow, orange and red pigment, respectively.

Monascus purpureus MK2를 이용하여 수용성 홍국 천연색소 생산을 위한 최적 배양조건에 대한 연구 결과, 탄소원으로 wheat flour 3.0% 첨가, 질소원으로 $NaNO_3$ 0.15%, 인산염으로 $K_{2}HPO_4$ 농도가 0.2% 및 $MgSO_4\;7H_{2}O$의 농도가 0.05%일 때 가장 높은 수용성 홍국 천연색소 생성을 나타내었다. 또한 배양온도는 $30^{\circ}C$, 초기 pH가 7.0, 진탕속도 130 rpm 및 배양시간 7일 일 때 수용성 홍국 천연색소의 생성능은 모 균주의 생성능인 3.12 unit(황색), 1.87 unit(오렌지), 1.77 unit(적색)에 비해 각각 9.33, 19.70, 27.64배 높은 29.10 unit(황색), 36.84 unit(오렌지), 48.92 unit(적색)로 가장 높은 수용성 홍국 천연색소의 생성능을 나타내었다.
