Chloroflexota are often abundant members of the biomass in wastewater treatment plants (WWTPs) worldwide, typically with a filamentous morphology, forming the backbones of the activated sludge floc. However, their overgrowth can often cause operational issues connected to poor settling or foaming, impairing effluent quality and increasing operational costs. Despite their importance, few Chloroflexota genera have been characterized so far. Here, we present a comprehensive overview of Chloroflexota abundant in WWTPs worldwide and an in-depth characterization of their morphology, phylogeny, and ecophysiology, obtaining a broad understanding of their ecological role in activated sludge.
绿弯菌门通常是全球废水处理厂（WWTP）中生物量的丰富成员，通常具有丝状形态，形成活性污泥絮体的骨干。然而，它们的过度生长常常会导致与沉降不良或泡沫有关的操作问题，从而影响出水质量并增加运营成本。尽管它们很重要，但到目前为止，只有少数绿弯菌门属被描述过。在这里，我们全面概述了全球 WWTP 中丰富的绿弯菌门，并深入分析了它们的形态、系统发育和生理生态，广泛了解了它们在活性污泥中的生态作用。
