We evaluated the competitive fitness of three phenanthrene-mineralizing isolates that were provided with nonsorbed or sorbed phenanthrene in competition experiments. One isolate had a clear advantage when presented with Amberlite IRC-50-sorbed phenanthrene, yet none were favored when presented with nonsorbed or Amberlite XAD-7-sorbed phenanthrene. Our results indicate that contaminant availability alone does not determine the isolates' competitive fitness.
我们在竞争实验中评估了三种能够矿化菲的分离菌株的竞争适应性,实验为它们提供了未吸附或已吸附菲的环境。当使用Amberlite IRC - 50吸附的菲时,有一种分离菌株具有明显优势,但当使用未吸附或Amberlite XAD - 7吸附的菲时,没有一种分离菌株具有优势。我们的结果表明,仅污染物的可利用性并不能决定分离菌株的竞争适应性。
