  1. Three separate experiments showed consistent results and representative examples are shown. The standard deviation represents variation between three biological replicates. All values shown are significant differences (P ≤ 0.05) in accumulation with addition of an EI relative to absence of EI.
  2. a fold-change compared to corresponding bacterial sample in the absence of CCCP.
  3. b fold-change compared to corresponding bacterial sample in the absence of PAβN.
