Abstract

Candidatus Microthrix is a widespread filamentous bacterium frequently causing activated sludge settling problems, making it an important member of microbial community in WWTPs. Recent developments of bioinformatic tools allow for the first time to use amplicon sequencing results to study members of activated sludge community with high phylogenetic resolution and to design species-specific FISH probes. Based on 12 years of data from 22 Danish WWTPs we demonstrate low species-level diversity of Candidatus Microthrix, widespread occurrence of the two major species in WWTPs and their unequal impact on sludge settling. We also visualize their morphology using novel FISH probes.
