Figure 6: NMDS plot showing distances between bacterial community structures, calculated based on ΘYC dissimilarities of OTUs (Stress: 0.271; R2=0.661). Symbol colors designate different treatment groups: PAH+ HK44- (L1, L2, L4) are black; PAH- HK44+ (L3, L5) are white; PAH+ HK44- (L6) are grey.* indicates duplicate libraries constructed from the same sample.
