邻苯二甲酸二(2-乙基己基)酯(DEHP)作为增塑剂使用,造成环境污染。本文研究了DEHP对土壤微生物功能、结构和遗传多样性的影响。土壤中DEHP的浓度分别为0、0.1、1、10和50 mg/kg,试验周期为28 d。DEHP在前14天内降低了土壤微生物的数量、丰度、物种优势度和均匀性。此外,微生物对碳源(碳水化合物、淀粉、氨基酸、代谢产物)的利用效率在28 d后受到影响,但影响逐渐减弱。变性梯度凝胶电泳和克隆文库分析表明,DEHP污染土壤中的优势微生物为鞘氨醇单胞菌和芽孢杆菌,分别属于酸性细菌纲和变形杆菌纲。当DEHP浓度为0.1或1 mg/kg时,酸性细菌的相对丰度较高,当DEHP浓度为10或50 mg/kg时,变形菌的相对丰度较高。
Di-(2-ethylhcxyl) phthalate (DEHP) is applied as plasticizer, which results in the pollution of environment. In this study, the effects of DEHP on soil microbial functions, structure and genetic diversity were investigated. The concentration of DEHP in the soil were 0, 0.1, 1, 10 and 50 mg/kg, and the experimental period were 28 days. DEHP reduced the quantity, abundance, species dominance and homogeneity of soil microbes during the first 14 days. In addition, microbial utilization efficiency of carbon (carbohydrates, aliphatics, amino acids, metabolites) was impacted after 28 days, though the effects gradually weakened. Based on denaturing gradient gel electrophoresis and clone library analysis, in the presence of DEHP, the dominant microbes in the DEHP-contaminated soil wereSphingomonasandBacillus, which belonged to theAcidobacteriaandProteobacteriav, respectively. With 0.1 or 1 mg/kg of DEHP, the relative abundances ofAcidobacteriawere higher, and with 10 or 50 mg/kg of DEHP, the relative abundances ofProteobacteriawere higher.
