Relative abundance of archaeal 16S rRNA genes at genus (G) level based on the average ASV reads from triplicate samples, collected on different days. Where genus name could not be assigned to the sequences, the closest classified taxonomic level is presented; kingdom (K), phylum (P), class (C), order (O), family (F). (1) Start-up phase, (2) semi-continuous oleate feeding, (3) oleate pulse feeding, and (4) end of PASS and oleate feeding
