Abstract

Optimization of culture conditions for pigment production of Monascus purpureus P-57 mutant was investigated in liquid culture. The optimum composition of medium for the pigment production was $4\%$ rice power, $0.1\%$ beef extract, $0.03\%$ glutamic acid, $0.1\%\;MgSO_4{\cdot}7H_2O,\;0.25\%\;KH_2PO_4$, the optimum initial pH was 5.0. And the optimum culture conditions was at $30^{\circ}C$ for 8 days under 150 rpm with shaking. M. purpureus P-57 mutant produced the highest pigment as 356.04 units at red pigment and as 268.20 units at yellow pigment, and produced high cell mass as 15.00 g/L in liquid culture under the optimum conditions.

본 연구는 Monascus purpureus P-57 변이주를 이용하여 액체배양을 통한 세포내 색소 생성의 최적 배양조건을 규명 하고자 하였다. M. purpureus P-57의 색소생성을 위한 최적 배지조성은 $4\%$ rice powder, $0.1\%$ beef extract, $0.03\%$ glutamic acid, $0.1\%\;MgSO_4{\cdot}7H_2O,\;0.25\%\;KH_2PO_4$이며, 배지의 pH는 5.0이였다. 그리고 최적 배양조건은 $30^{\circ}C$ , 150 rpm에서 8일간 배양했을 때 가장 높은 색소 생성력을 나타내었다. M. purpureus P-57을 이상의 최적 조건에서 배양했을 때 적색 색소가 356.04 mit, 황색 색소가 268.20 unit으로 가장 많은 색소를 생성하였고, 균체량은 15.00 g/L를 생산할 수 있었다.
