Fig. 4From: Global prevalence of organohalide-respiring bacteria dechlorinating polychlorinated biphenyls in sewage sludgeQuantification of known organohalide-respiring bacteria (OHRB) and the reductive dehalogenase (RDase) gene in sludge microcosms dechlorinating PCBs. a Abundance of OHRB and RDase genes after 180 days of incubation and b their correlations with the dechlorination activity of PCBs (quantified by the decrease in average Cl/PCB). Dhc, Dehalococcoides; Dhg, Dehalogenimonas; Dhb, Dehalobacter. Pearson’s r and p values were obtained from one-way ANOVA testsBack to article page
