Competitive fitness of isolates enriched on phenanthrene sorbed to model phases.
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.
