Fig. 8

Significant differences of classified bacterial families between different reactors. The left panel shows differences of relative abundance in groups at 0 h and 150 h. The graph on the right shows the difference between groups according to the confidence level. The leftmost endpoint of each circle in the graph represents the lower 95% confidence interval of the mean difference, and the rightmost endpoint of the circle represents the upper 95% confidence interval. The center of the circle represents the difference in means. The group represented by the circle color has a high mean value. The far right displays the P-values for the significance test between the two time points of the corresponding family
