soil metagenome
A total of 12 samples with concentrations of CK, 0.5, 1, and 5 mgkg-1 (low, medium and high concentrations) were selected from soil samples inoculated in the laboratory at 0, 28 and 42 d (pre, middle and post 3 periods) during the culture period (before, during and after 3 periods) for metagomic sequencing which was commissioned by Shanghai Personal Biotechnology Company. In this study, the Illumina NovaSeq/HiSeq high-throughput sequencing platform and the Whole Genome Shotgun (WGS) method were used to obtain the abundance spectra of functional groups at each level
