The most dominant OTUs and their compositions in the bacterial 16S rRNA gene clone libraries and metagenomes of Z7 and Z8.

1The identity of 16S rRNA genes between representative sequence of each dominant OTU and their nearest bacteria or type strains.2Z7_PCR and Z8_PCR represent the proportion of each OTU in the 16S rRNA gene clone library of Z7 and Z8.3Z7_META and Z8_META represent the proportion of each OTU in all the 16S rRNA genes recovered from Z7 and Z8 metagenomic data.* Significant differential OTUs between Z7 and Z8 16S rRNA clone libraries were identified and filtered (q-value, The most dominant OTUs and their compositions in the bacterial 16S rRNA gene clone libraries and metagenomes of Z7 and Z8.
