초록

새싹채소로부터 분리된 E. faecium의 temperate phage 특성을 mitomycin C를 이용하여 E. faecium으로부터 D-19 phage와 F6 phage를 각각 분리하였다. 분리된 temperate phage는 형태학적 특성을 확인한 결과 모두 Siphoviridae에 속하는 것으로 나타났다. 그리고, 숙주 저해 범위는 55개의 숙주중에서 D-19 phage는 5주, F6 phage는 3주의 E. faecium만을 용균시킬 수 있는 것으로 확인하였다. 다양한 ethanol 농도에서의 안정성은 고농도에서도 매우 안정한 것으로 확인되었으며, pH의 안정성도 pH 4까지 안정한 것으로 나타났다. 본 연구를 통해 아직 연구가 많이 이루어지지 않은 E. faecium의 temperate phage는 host spectrum이 넓지 않은 것으로 나타났고 pH, 온도 등의 환경인자에 상당히 강한 안정성을 가지고 있는 것으로 나타났다.
