OTUs, operational taxonomic units; Coverage, Good's nonparametric coverage estimator; ACE, abundance-based coverage estimator; Chao1, richness estimator; Shannon, nonparametric Shannon diversity index.
Values are means of three replicates.
Means in the column followed by different letters are significantly different (P < 0.05).
** P < 0.01
*** P < 0.001.
