Table 4.
Comparison of range-weighted richness (Rr) for bacterial diversity at different stages of ATAD treatment obtained by various primer sets in this study and values reported in other studies from different industrial and native ecosystems. Rr was calculated for each DGGE profile obtained as described in Section 2. The highest Rr values are shown in bold.
