*Relative contribution of a genus in different libraries was calculated as percentage of the sequence of this genus to all sequences in this sample.

Sequence that could not be classified into any known group in phyla level were assigned as “Unclassified bacteria”; Sequence that could not be classified into any known group in class, order, family and genus levels were assigned as “Other”.
