The high-throughput Illumina NovaSeq sequencing method was adopted to study the effect of artificial root exudates and
L. root exudates on the community structure,
and
diversity, and gene function of the bacterial communities in pyrene-contaminated soils to understand the impact of root exudates on microbial communities. The results showed that root exudates did not significantly change the composition of pyrene-contaminated soil bacterial communities. The main dominant bacterial phyla were Proteobacteria, Actinobacteria, Firmicutes, Bacteroidetes, etc. The main dominant bacterial genera were
, etc. Root exudates changed the relative abundance of dominant species to a different extent and resulted in discriminating bacteria. The genus
belonging to Proteobacteria and
belonging to Firmicutes were the biomarkers in the artificial root exudates group and the actual root exudate group, respectively. The common discriminating bacteria in both root exudate groups compared to those in the control group were polycycli
