Sequencing was performed using the MiSeq™ Personal Sequencing System (Illumina, San Diego, CA, USA) with 2 × 156 bp paired end. The ‘Trim reads’ tool in CLC Genomics Workbench 20.0 (Qiagen, Hilden, Germany) was used to efficiently filter out and remove nucleotides corresponding to primers 515F and Pro-mod-805R. Demultiplexing was performed using the deML package [45 (link)], using zero available mismatches option. Then, read pairs were processed with DADA2 pipeline [46 (link)], according to published.
