Figure 1.

Phylogenetic tree based on sequences obtained from the biofilm samples. "I" after a clone number refers to a biofilm sample from the internal site, "E" refers to a biofilm sample from the external site, and "M" refers to biofilm from a mixed sample. Only consensus sequences are shown in the tree. The scale bar of 0.1 corresponds to 10% estimated sequence deviation. Gammaproteobacteria, the Firmicutes and Actinobacteria were present on all three sample types, while Beta- and Deltaproteobacteria were only present in samples from the external site and Alphaproteobacteria in mixed samples.
