뽕나무 첨가 배지에서 배양한 버섯균사체 배양물의 자동산화 억제 효과

국문 초록 (Abstract)

BMM에 여러 가지 버섯균을 7일 동안 액체배양하고 균사를 제거한 배양물에 대한 항산화성에 관한 연구를 수행하였다. 시료(1 ㎎)를 275 μmol linoleic acid가 함유된 배양액에 첨가하고 shaking incubator(200 rpm, 40℃)에 16일 동안 배양하면서 생성된 POV와 MA의 함량의 조사하였다. 이 결과를 BM에서 배양한 버섯균사체배양물과 BMM 자체의 POV 및 MA 생성 결과와 비교하였다. AB-BMM과 HE-BMM의 항산화능이 다른 버섯균사체배양물이나 BMM보다 우수하였다. 따라서 이 연구결과는 뽕나무는 버섯균사체액체배양물의 항산화성을 증가시켰고, AB-BMM 및 HE-BMM은 항산화물로 활용할 수 있음을 의미한다.

Effect of mulberry tree powders on the antioxidant activity of submerged-liquid culture of mushrooms was investigated. Agaricus blazei (AB), Hericicum erinacium (HE), Pleurotus ostreatus (PO), Phellinus linteus (PL) and Paecilomyces japonicus (PJ) were cultured in a shaking incubator (200 rpm, 25℃) for 7 days in culture media: 1) basal medium (BM) and 2) BM＋1% mulberry tree powders (BMM). Hot water extracts from the submerged-liquid cultures of mushrooms and BMM were freeze-dried for the measurement of antioxidant activity, of which reaction mixture (25 mL: 10 mL of 0.2 M sodium phosphate buffer, pH 8.0; 4.5 mL distilled water; and 10.5 mL ethanol) contained 275 μmol linoleic acid and one mg test sample. The reaction mixture was incubated in a shaking incubator (200 rpm, 40℃) for 16 days. Peroxide value (POV) was measured for a period of over 16 days, and malonaldehyde (MA) was determined only for samples from the day 16 of incubation. Mycelial weight of mushroom strains cultured in BMM was greater than BM. The antioxidant activities of AB-cultured in BMM (AB-BMM) and HE-cultured in BMM (HE-BMM) were superior to those of other mushroom strains-cultured in BMM or BM and of BMM. These results suggest that mulberry tree powders enhance the antioxidant activity of submerged-liquid culture of mushroom strains. The AB-BMM and HE-BMM were the most active cultures.
