Total abundance of predator populations in 4 SBRs over 11 weeks of granulation. a Viral sequences were classified accordingly to family level (b) with corresponding Spearman correlation between viral families and 50th percentile sludge particle size. c Distance based redundancy analysis (dbRDA) ordination of the effect of viral dynamics on the changes in bacterial community with aerobic granulation. d Top 10 most abundant eukaryotic OTUs with (e) corresponding Spearman correlation with 50th percentile sludge particle size differentiated into the three phases of granulation. Protozoan OTUs are in bold. All read counts are natural log transformed before analysis. Viral analyses were based on viral metagenome (DNA) reads while eukaryotic OTUs were based on Ribotagger tags (RNA). The correlation matrixes were clustered based on Bray Curtis distance with between-group average linkage (UPGMA) method. The correlation matrixes are color-coded where yellow and blue indicate positive and negative correlations, respectively. Where correlations cannot be made, the tile is coloured white
