We also found that high fitness in populations evolved in the complex environment was driven by rare variants (frequency <0.1%) that inhibited the ancestral strain, which was used as a common competitor for fitness measurements.

In particular, the potential for the sort of synergistic interactions we observed to impact P. aeruginosa infections is ripe for further research!
