Table 1.

Species richness, diversity and evenness indices of epimural bacteria are depicted for sampling time points B (baseline), S1 (SARA 1), CB (challenge break), and S2 (SARA 2).

Significant differences (between sampling time points) in rows are marked with different letters.

SEM = standard error of the mean.

ACE = abundance-based coverage estimator.
