Fig. 1From: Global prevalence of organohalide-respiring bacteria dechlorinating polychlorinated biphenyls in sewage sludgeGlobal occurrence of organohalide-respiring bacteria (OHRB) in sewage sludge from geographically disparate regions. The boxes show the relative abundance of putative OHRB, and each box indicates one sludge sample. The green parts of the pie charts indicate the percentages of sludge samples containing OHRB on each continent. n, the total number of sludge samples analyzedBack to article page
