邻苯二甲酸二甲酯 (DMP) 是一种已知的内分泌干扰物，也是邻苯二甲酸酯 (PAE) 的一种，是一种普遍存在的污染物。它对生物体的影响引起了人们的高度关注。本研究利用微观模型测试了黑土中DMP污染对细菌群落和功能的影响。结果表明，DMP 污染降低了操作分类单元（OTU）丰富度和细菌多样性。一些与氮代谢相关的属的相对百分比因DMP污染而增加，而其他一些对土壤健康极其有益的属的相对百分比则因DMP污染而减少。此外，低浓度（5、10和20 mg/kg）DMP处理增加了一些具有降解DMP能力的属的相对百分比，但高浓度DMP处理（40 mg/kg）降低了这些属的相对百分比。显然，DMP污染改变了黑土中细菌的群落结构，扰乱了微生物的代谢活性和功能多样性。我们的研究结果表明，DMP污染可以改变黑土微生物的新陈代谢和生物多样性，从而直接影响肥力和生态系统功能。
Dimethyl phthalate (DMP), a known endocrine disruptor and one of the phthalate esters (PAEs), is a ubiquitous pollutant. Its impacts on living organisms have aroused great concern. In this study, the impacts of DMP contamination on bacterial communities and functions were tested by using microcosm model in black soils. The results showed that the operational taxonomic unit (OTUs) richness and bacterial diversity were reduced by DMP contamination. The relative percentages of some genera associated with nitrogen metabolism were increased by DMP contamination, while the relative percentages of some other genera that were extremely beneficial to soil health were decreased by DMP contamination. Further, the relative percentages of some genera that possessed the capability to degrade DMP were increased by the DMP treatment at low concentrations (5, 10, and 20 mg/kg), but were decreased by the high concentration DMP treatment (40 mg/kg). Clearly, DMP contamination changed the bacterial community structure and disturbed the metabolic activity and functional diversity of the microbes in black soils. Our results suggest that DMP pollution can alter the metabolism and biodiversity of black soil microorganisms, thereby directly impact fertility and ecosystem functions.
