Diversity and abundance of filamentous and non-filamentous "<i>Leptothrix"</i> in global wastewater treatment plants.

ABSTRACT: Species belonging to the genus Leptothrix are widely distributed in the environment and in activated sludge (AS) wastewater treatment plants (WWTPs). They are commonly found in iron-rich environments and reported to cause filamentous bulking in WWTPs. In this study, the diversity, distribution, and metabolic potential of the most prevalent Leptothrix spp. found in AS worldwide were studied. Our 16S rRNA amplicon survey showed that Leptothrix belongs to the general core community of AS worldwide, comprising 32 species with four species being most commonly found. Their taxonomic classification was re-evaluated based on both 16S rRNA gene and genome-based phylogenetic analysis showing that three of the most abundant "Leptothrix" species represented species in three
