Fig. 4From: Microbial community regulation and performance enhancement in gas biofilters by interrupting bacterial communicationa Relative abundance of the top 30 genera in BF and QQBF biofilm samples during the whole operation. Significantly different (p < 0.01) QS-related genes in BF and QQBF biofilm samples on b day 25 and d day 90. c Dissimilarities among the biofilm samples in BF and QQBF presented by NMDS analysis based on the Bray−Curtis distanceBack to article page
