Fig. 5From: Microbial community compositions in different functional zones of Carrousel oxidation ditch system for domestic wastewater treatmentLEfSe analysis results of the anaerobic-, anoxic- and oxic-zones in carrousel oxidization ditch system. a LDA scores to feature differentially abundant, b Taxonomic representation of statistically and biologically consistent differences. Differences were indicated in the color of the most abundant taxa (yellow represented non-significant, and red indicated the anoxic-zone). Each circle’s diameter was proportional to the taxonomic abundanceBack to article page
