Dynamics in bacterial community assembly. a Heat map shows the dynamics of OTUs that have a relative abundance > 0.3% in at least half of the collected samples. Side dendrogram represents the hierarchical clustering based on Pearson correlation. b Ternary plot shows the abundance comparison of the 58 newly recovered MAGs in three different anammox sludge samples. The value of a given MAG in each sample is equal to its corresponding abundance divided by the abundance sum of this MAG in the three anammox sludge samples. The abundance of MAGs in the triplicate samples (days 204, 210, and 213) was averaged. The organisms that were mainly identified in the seed sludge and the studied PNA reactor are encircled with blue and red circles. The symbol size represents the genome size
