Relative abundances of archaeal 16S rRNA genes at genus (G) level based on the average ASV reads from triplicate samples collected on different days from digesters F1, F2, F3, F4, F5, and F6. Where genus name could not be assigned (NA) to the sequences, the closest classified taxonomic level is presented; kingdom (K), phylum (P), class (C), order (O), family (F)
