Fig. 6From: The bacterial community significantly promotes cast iron corrosion in reclaimed wastewater distribution systemsExtended error bar plots showing the abundance of genera differing significantly between the NaClOdisinfection and NONdisinfection reactors with an effect size of 0.75. a Genera in the black layer of stage II; b genera in the black layer of stage III; c genera in the yellow layer of stage II; d genera in the yellow layer of stage III. The numbers in the parentheses represent the amounts of OTUs belonging to the genus correspondingly to Fig. 4. The red numbers represent the AP-type OTUs; the orange numbers represent the RP-type OTUs; and the light purple numbers represent the RI-type OTUsBack to article page
