The percent relative abundance represents the mean for genera across (a) different temperature range and primary substrates, and (b) different countries considering only mesophilic ADs treating mainly wastewater sludge. Colored circles next to the genus labels indicate whether the genera have previously been identified as growing in ADs at Danish WWTPs according to Jiang et al.7. Blue: >50% of ASVs classified as growing; Yellow: 20–50% of ASVs classified as growing. Red: <20% of ASVs classified as growing. Gray: No information available for the specific genus.
