Variation among sample A replicate libraries from PowerBiofilm and Maxwell extractions. Relative abundance of bacterial phyla (class for Proteobacteria) from DNA extracted from sample A replicate libraries (n = 3 PowerBiofilm replicate libraries and n = 3 Maxwell replicate libraries). Unclassified sequences and phyla with membership < 1% of total sequences were pooled into the classification labeled "Other". AMOVA: p = 0.106.
