Abstract

We have studied the kinetic characteristics of several isolates of Escherichia coli Z905 recombinant strain after introduction of the strain into model aquatic ecosystems. Most E. coli Z905 isolates grown as batch cultures under selective conditions (0.5 microgram/ml ampicillin) showed better kinetic characteristics of growth than did related species of native microflora, which originally populated laboratory microcosms.

摘要

我们将大肠杆菌Z905重组菌株引入模型水生生态系统后，研究了该菌株几个分离株的动力学特征。在选择性条件（0.5微克/毫升氨苄青霉素）下以分批培养方式生长的大多数大肠杆菌Z905分离株，其生长的动力学特征比最初在实验室微观世界中繁殖的本地微生物区系的相关物种更好。
