^aBlast searching against the NCBI bacterial 16S database. Valid assignments were based on E-values < 1e⁻⁰³ and alignments larger than 800 bp. N/A means no species was found for the respective genus. Species matching with those present in the mock community are underlined and in bold. Rows with genera, species, and read counts highlighted with asterisk (*) indicate they are not expected to be present in the mock community
