In the previous paper, we isolated a bacterium that can hydrolyze various organic materials from soybean paste, including cellulose, lipids, starch, and protein. The activity and chemical properties of the crude enzymes produced by the isolate Bacillus subtilis CK-2 were further investigated. Cellul...

Bacillus sp. 이 생산하는 protease의 pH에 따른 효소활성을 측정한 결과는 어떠한가? | Protease는 pH 7.0~8.5의 범위에서 높은 활성을 나타내었으며, pH 8.0에서 0.74 units/mg protein으로 가장 높은 활성을 보였다. pH 6.0 이하에서는 효소활성이 거의 나타나지 않았으며, pH 9.5에서도 60% 정도의 효소활성이 나타났다. 기존의 보고[7, 14, 25, 35]에서 Bacillus sp. | |
Bacillus subtilis CK-2는 어떤 유기물을 분해하나요? | 본 연구에서는 섬유소, 녹말, 단백질, 지질 등 다양한 유기물을 분해하는 것으로 확인된 Bacillus subtilis CK-2 [19]가 분비하는 각종 가수분해효소들의 특성을 확인함으로써 이 균주의 산업적 활용을 위한 기초 자료를 마련하고자 하였다 | |
자연계의 유기성 폐기물을 분해하는 미생물의 종류는? | 유기성 폐기물을 구성하는 섬유소, 녹말, 단백질 등을 효과적으로 분해하는 미생물로는 곰팡이, 효모 등의 진균류와 세균 등이 있으며, 이들은 모두 자연계의 유기물을 분해하여 물질의 순환에 기여할 뿐만 아니라, 특히 세균이 분비하는 여러 가지 유기물 분해효소들은 산업적으로 다양하게 활용되고 있다[15, 16, 18]. |
