概括

污水处理厂 (WWTP) 的废水将药品和个人护理产品 (PPCP) 引入城市水流,改变了微生物群落. 然而,抗生素耐药性基因与更广泛的流域影响有关,而不仅仅是WWTP废水.

科学领域:

环境科学环境科学
环境化学环境化学
微生物学微生物学

背景情况:

污水处理厂 (WWTP) 的废水是药品和个人护理产品 (PPCP) 进入地表水的潜在来源.
这些生物活性化合物可能会在水生微生物群落中选择耐药性特征和种群.

研究的目的:

为了调查WWTP废水是否是PPCP的点源到城市流.
为了确定废水输入对谷底微生物群落组成的影响.
评估废水输入是否会增加盆地微生物群落中抗生素耐药性决定因素的丰富性.

主要方法:

从芝加哥地铁地区的城市和农村溪流收集水和沉积物.
在水样中的45种常见PPCP的量化度.
分析了盆地细菌群体的组成,并量化了intI1基因的丰富性.

主要成果:

一条流量较高的污水流 (80%) 显示了PCPCP度的增加和下游细菌群落的变化.
在高排水流中观察到光合作用生物的丰度下降.
与农村流相比,城市流中的基因丰度更高,这表明流域规模的影响.

结论:

水流可以成为PPCP的重要来源,推动水生微生物群落的变化.
虽然在高流量场景中观察到废水的影响,但intI1基因丰富性似乎更多地受到更广泛的流域人类影响的影响.
非点源也会导致城市河流中的PPCP污染.

Environmental Applications of Microorganisms

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
