Principled coordinate analysis (PCoA) for the four groups of different industrial polluted sediment communities at the OTU level (a). Community composition of bacteria in the phylum level (b) and the family level (d) in sediment samples. (c) Significantly different relative abundance of dominant bacteria in four groups of different industrial polluted sediments. One-way analysis of variance (ANOVA) was used to evaluate the importance of comparisons between indicated groups. * P < 0.05, ** P < 0.01, *** P < 0.001
