Fig. 4From: Degradation of a benzene–toluene mixture by hydrocarbon-adapted bacterial communitiesRelationship between the composition of bacterial communities from five groundwater samples 309d, DW3s, W18i, 309s, 308i over 6 days. Relative depths of wells are indicated by: d deep, i intermediate, s shallow The dendrogram was created using Bray Curtis similarity which treats the data on a presence/absence basis and equates to the Sorensen coefficientBack to article page
