Distributions of bacteria in the 13 samples at the genus level. Taxa were represented at > 0.5% frequency in at least one sample. “Others” refers to the taxa with a maximum abundance of < 0.5% in any sample. Unclassified refers to the sequences that could not be assigned to known bacterial genus. F_ty stands for the sample collected from a farmland neighbouring the contaminated field this year. BA_3d, BA_11d, BA_47d, and BA_125d represent the samples collected after 3, 11, 47, and 125 days, respectively, from the beginning of the remediation process in the BA block. BS_11d, BS_47d, and BS_125d represent the samples collected after 11, 47, and 125 days, respectively, from the beginning of the remediation process in the BS block. Phyto_125d represents the sample collected 125 days after the beginning of the remediation process in the Phyto block. Ctrl_oya is a sample that was collected in the contaminated site 1 year ago. F_oya is the sample collected from a farmland neighbouring the contaminated field 1 year ago
