摘要
邻苯二甲酸二甲酯(DMP)在土壤中的过量积累对土壤生态系统和人类健康造成了巨大的压力。本研究探讨了利用细菌群体感应信号分子n -酰基同丝氨酸内酯(AHLs)加强植物修复DMP污染土壤的可行性。研究了n -丁基- l-高丝氨酸内酯(C4-HSL)对大豆(Glycine max L.)生理及植物修复效果的影响。结果表明,C4-HSL显著提高了大豆对DMP污染土壤的修复效率,培养28 d后DMP去除率达到87.40 %。施用C4-HSL通过促进叶绿素合成显著增强大豆光合作用,并通过显著降低丙二醛含量增强抗氧化能力。C4-HSL的存在还能刺激植物生长,提高土壤酶活性,可能有助于土壤养分循环和污染物降解。此外,C4-HSL修饰了细菌群落,增加了与DMP降解相关的细菌(Proteobacteria,放线菌门)和促进植物生长相关的细菌(Micromonosporales, Sphingomonadaceae)的相对丰度。总的来说,本研究提出ahls辅助植物修复为DMP修复提供了一个有前途的、环保的策略。该方法具有经济效益和生态效益,同时减少了对大豆的损害,为农业实际应用奠定了基础。
Innovative N-butyryl-L-homoserine lactones-assisted strategy for phytoremediation: Improving soybean growth and soil quality in dimethyl phthalate remediation
The excessive accumulation of dimethyl phthalate (DMP) in soil exerts tremendous pressure on soil ecosystems and human health. This study explored the feasibility of using bacterial quorum sensing signal molecules, N-acyl-homoserine lactones (AHLs), to enhance phytoremediation of DMP contaminated soil. The effects of N-butyryl-L-homoserine lactone (C4-HSL) on soybean (Glycine max L.) physiology and phytoremediation efficiency were assessed. Results indicated that C4-HSL significantly promoted the efficiency of soybean in remediating DMP contaminated soil, achieving an 87.40 % DMP removal efficiency after 28 d cultivation. Applying C4-HSL significantly enhanced soybean photosynthetic by the potential promotion of chlorophyll synthesis and bolstered the antioxidant with a notable reduction in malondialdehyde content. The presence of C4-HSL also stimulated plant growth and improved soil enzymatic activities, likely aiding in nutrient cycling and pollutant degradation in soil. Moreover, C4-HSL modified the bacterial community, increasing the relative abundance of bacteria related to DMP degradation (Proteobacteria, Actinobacteria) and plant growth promotion (Micromonosporales, Sphingomonadaceae). In general, this study proposed that AHLs-assisted phytoremediation offers a promising, eco-friendly strategy for DMP remediation. This approach provides economic and ecological benefits while reducing damage to soybeans and lays the groundwork for practical applications in agriculture.
期刊介绍:
The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice.
PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers.
PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
