The effects of these processes on soil bacteria are not well understood, and soil washing and landfarming techniques are commonly used to remove total petroleum hydrocarbon contaminated soil, but the effects of these procedures on soil bacteria are not well understood. By metagenomic analysis, four distinct states of soil were collected from a soil remediation center to investigate the effects of TPH and soil remediation procedures on soil bacterial populations. LF revealed greater bacterial richness and diversity than SW and LF remediation methods, meaning that LF is a more effective method for TPH remediation in terms of microbial recovery. These results show that soil pollution can change the diversity of microbial species and different remediation methods for rebuilding bacterial populations and diversity. In conclusion, the landfarming process of TPH remediation is more effective than soil washing from the perspective of bacterial ecology.
