Effect of dosed assimilable organic carbon (AOC) on gene copy numbers. a Correlations between the numbers of total bacteria and dosed AOC level. Linear regression lines are color-coded according to temperature as indicated. Means and standard errors from replicated SWHs are shown (n = 6 for combined pipe material data at 32–49 °C, n = 3 for 53 °C, with each pipe material plotted individually). b Distribution of gene copy numbers of specific microbes of interest under temperature/pipe conditions where a significant effect of AOC supplementation was noted. For each boxplot, n = 9 for 32 °C and n = 3 for 37 °C. Asterisk indicates significant difference compared to lower AOC levels according to post hoc ANOVA test
