Microbial Community Structure Analysis in the Combined Remediation of Petroleum - Contaminated Soil by Immobilized Microbial Communities and Plants
This experiment aimed to explore the impact of immobilized microbial communities and plants on the remediation of petroleum - contaminated soil. Samples were gathered from an experimental area of Nanyang Normal University. They were divided into five groups: the control group (CK) without any treatment, the immobilized microbial community group (IM) with added immobilized microbial communities, the petroleum - contaminated soil group (OP) with artificially added petroleum, the immobilized microbial community + plant composite group (CP) with both immobilized microbial communities and plants (Sorghum sudanense), and the plant remediation group (PR) with only plants (Sorghum sudanense). Each group had five replicates. DNA was extracted from the samples for sequencing and subsequent analyses, including microbial community structure analysis, diversity analysis, and correlation analysis, to understand the role of different treatments in soil remediation and the changes in microbial communities.
