Fig. 7From: Microbial community compositions in different functional zones of Carrousel oxidation ditch system for domestic wastewater treatmentLEfSe analysis results of the WWTPs. 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, green and blue indicated the WWTP of GDHZ, MYYX and ZZLQ, respectively). Each circle’s diameter was proportional to the taxonomic abundanceBack to article page
