Physiological and morphological changes in Escherichia coli exposed to oligotrophic natural waters and reagent grade water were studied. Several lines of evidence indicated that short-term exposure in water causes cellular envelope damage. Increasing susceptibility to lysozyme, lag time before cell division, and injury as defined by differential counts on selective and nonselective media occurred with exposure time. Electron micrographs of injured cells showed morphological changes in cell envelope.
研究了暴露于贫营养天然水和试剂级水中的大肠杆菌的生理和形态变化。多条证据表明，在水中短期暴露会导致细胞包膜损伤。随着暴露时间的延长，对溶菌酶的敏感性增加、细胞分裂前的延迟期以及在选择性和非选择性培养基上通过差异计数定义的损伤均会出现。受损细胞的电子显微镜照片显示了细胞包膜的形态变化。
