1 UB, uncultured bacteria;
2 Percentage among the 128 cloned sequences (>97 identity);
3 Percentage among the 5,5713 metagenomic reads (>97 identity);
4 Percentage among 319 cloned sequences (Li et. al. (2007));
5 OTUs were classified to Firmcutes based on RDP. However, phylogenetic analysis showed they belonged to Mollicutes.
