The impact of drinking water quality, in particular the planktonic microbiome, on the bacterial and fungal community composition of biofilms in drinking water infrastructure is explored. Understanding drinking water biofilms is critical as biofilms can degrade water quality and potentially present a public health risk if pathogens are released. Biofilms were developed for 12 months in three state-of-the-art pipe loop facilities installed at water treatment works and hence supplied by distinct treated drinking water and unique planktonic bacterial and fungal microbiomes. Each pipe loop had identical physical conditions, including pipe diameter, material and hydraulic regime (shear stress and turbulence). Despite the different bulk-waters, the bacterial and fungal community composition of the biofilm within each loop were remarkably similar, although in different quantities. The similarity between the biofilms from unique systems, with significantly different planktonic microbiomes, suggests shared selective pressures across the different sites which are independent of the varying water qualities, including planktonic community. This suggests that taking a global view of biofilm microbiome management is potentially feasible and that approaches controlling material or hydraulics may be best way to do this.
本文探讨了饮用水水质,特别是浮游微生物群,对饮用水基础设施中生物膜细菌和真菌群落组成的影响。了解饮用水生物膜至关重要,因为生物膜会降低水质,如果释放出病原体,还可能带来公共健康风险。在安装于水处理厂的三个先进管道回路设施中培养生物膜12个月,这些设施由不同的处理后饮用水以及独特的浮游细菌和真菌微生物群供水。每个管道回路具有相同的物理条件,包括管道直径、材料和水力状况(剪切应力和湍流)。尽管原水不同,但每个回路内生物膜的细菌和真菌群落组成非常相似,尽管数量不同。来自独特系统的生物膜之间具有相似性,其浮游微生物群差异显著,这表明不同地点存在共同的选择压力,这些压力独立于包括浮游群落在内的不同水质。这表明从全球视角管理生物膜微生物群可能是可行的,控制材料或水力的方法可能是实现这一目标的最佳途径。
