Abstract

Cultivation conditions for overproduction of lovastatins were investigated from the lovastatin producing strain N-03 which was obtained with NTG (N-methyl-N'-nitro-nitrosoguanidine) treatment from Aspergiliu ferrous ATCC 20542. Produced lactone and acid form of lovastatin were detected, and analyzed by HPLC method. In liquid culture, medium No. 2 containing soy protein produced higher amounts of the lovastatins than medium No. 1 (contained rapeseed oil). In solid culture, maximum production was obtained at 28$^{\circ}C$ for 15 days cultivation using cooked wheat bran. For the overproduction of lovastatin from this strain, solid culture method using plastic bag is more superior than liquid culture.

공시균인 A .terreus mutant로부터 lovastatin의 생산성을 극대화할 수 있는 조건을 확립하고자 액체 배양법 및 고체 배양법 을 이용하여 HPLC를 통해 분석하였다. Lovastaton의 생산을 위해 액체 배양에서는 균사체 접종법인 No. 2배지를 사용한 전배양 및 본배양법이 포자접종법인 No. 1배지를 사용한 경우보다 lovastatin의 생산이 더 우수하였다. 고체 배양법에서는 분쇄 밀의 호화전분을 사용하여 28$^{\circ}C$, 15일간 배양시 lovastatin의 생산이 가장 우수하였으며 대량배양을 위해 배양용기를 달리하여 배양하였으며 cap을 부착하는 내열성 plastic bag을 이용하여 배양한 결과 두 방향으로 cap을 부착하여 통기량을 조절한 배양에서 lovastatin의 생산이 가장 우수하게 나타났다.
