Comparison of diversity indices estimated from two artificial and two experimental communities.

For the artificial communities, the analysis includes the original communities, and the communities obtained after a theoretically random amplification and after simulating the proposed amplification model. For the experimental communities, results of the 16S rRNA analysis from metagenome analysis through direct sequencing (lacking amplification by PCR) and 16S rRNA amplicon analysis after PCR amplification are presented.1Number of taxa detected during the analyses. For the artificial communities 108 sequences were screened. For the experimental communities around 103 sequences were processed.
