Fig. 6From: Microbial community dynamics in an ANAMMOX reactor for piggery wastewater treatment with startup, raising nitrogen load, and stable performancea Neighbor-joining tree of anammox bacterial OTUs, based on 16S rRNA gene fragments. Bootstrap values (> 50%) shown on branch nodes are based on 1000 trials. Bar: evolutionary distance 0.01. b Relative abundance of these OTUs during the entire running period.
