초록
Escherichia coli(ATCC 11115)에 실험실등에서 상용하는 여러가지 항균제를 시간별로 처리, 그 변화양상을 전자현미경으로 관찰한 바 그 결과를 요약하면 다음과 같다. 1) 대조군은 3층의 단일막으로 형성된 세포벽에 둘러쌓여 있으며 세포질은 전자밀도가 낮은 nucleoid와 ribosme들이 산재하여 있음을 관찰할 수 있었다. 2) 70% ethanol용액 처리군은 핵물질을 관찰할 수 없었고 세포질은 세포 중앙부로 응집되어 있었으며 세포벽의 외부에서는 bleb 들을 관찰 할 수 있었다. 3) 3%
An electron microscopic study has been made of the effects of change of cell structure of Escherichia coli treated with several disinfectants. The alterations observed as follows: 1. Nucleoid, cytoplasm which contain ribosomes and cell wall appeared to be composed of a parallel triple. layered membrane can observed in control Escherichia coli. 2. The nuclear material was no longer demonstrable in its normal sites. The cytoplasm lost its granularity, became homogeneous and disruption of cell wall were observed by the treatment with 70% ethyl alcohol and 3%
