| 英文摘要 | The cadmiumcontamination in the paddy soil results in serious environmental pollutions. In situ soil remediation based on the applications of additives such as functional microorganisms and biochars has gradually attained more attentions. However, how these exogenous additives affect the local microbial communities is less discussed. In this study, a heavy metal resistant bacterium (Pseudomonas chenduensis, strain MBR) and biochar derived from oil palm fibers were separately added into the simulated Cd-contaminated paddy soil to investigate the roles of these additives in the soil remediation and regulating local microbial community. The results showed that compared with control, the addition of the strain MBR and biochar reduced the exchangeable/acid soluble cadmium fraction by 30% and 18%, respectively. Moreover, higher microbial diversity, more deterministic effects and less variation in microbial community were observed in the treatments supplemented with the strain MBR and biochar, and the increase of the deterministic effects on microbial interactions was demonstrated by network analysis further. Additionally, the abundance of the strain MBR in the paddy soil decreased as time passed, which maximally decreased the disturbance for the local micro-ecological niche and ensured ecological security. These results showed that two additives supplementation, in particular Pseudomonas chenduensis, can significantly decrease cadmium availability, contributing to the reduction of the disturbance on soil microbial community and maintaining microbial stability under cadmium pressure. It highlights a new criterion referred to microecology for the evaluation of the roles of additives in local soil remediation. (c) 2018 Elsevier B.V. All rights reserved. |
