Fig. 3From: Effluent solids recirculation to municipal sludge digesters enhances long-chain fatty acids degradation capacityRelative abundance of bacterial 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; phylum (P), class (C), order (O), family (F). Bacteria with relative abundance of ≥ 3% of total bacteria on at least one sampling occasion are depicted.
