Context. The genus Tetrasphaera belongs, along with Ca. Accumulibacter and Dechloromonas, to the most abundant polyphosphate accumulating organisms (PAOs) worldwide in wastewater treatment plants with enhanced biological removal (EBPR). Several Tetrasphaera species are isolated, showing some dive...

Context. Slow sand filters (SSFs) remove organic matter and microbial pathogens for drinking water production. Despite the biological nature of SSFs and their effect on flora of the finished water, much remains unknown regarding their microbial communities.Gap. No study has described the developme...

Introduction: Anaerobic digestion (AD) at wastewater treatment plants (WWTPs) is carried out by groups of microorganisms, active in complex metabolic networks. Recent studies of community structure have shown that there are two large fractions, growing and non-growing, the latter being up > 40% of ...

Wastewater-based disease surveillance is a promising approach for monitoring community outbreaks. Here we describe a nationwide campaign to monitor SARS-CoV-2 in the wastewater of 159 counties in 40 U.S. states, covering 13% of the U.S. population from February 18 to June 2, 2020. Out of 1,751 total...

The importance of water quality for human consumption comprises different parameters, microbiological and chemical, including the concentration of metals, one of them manganese (Mn) which is abundant in the earth and exists as a component of more than 30 kinds of manganese oxides/hydroxide minerals....

Water conservation efforts have led to decreased water flow in buildings. Without resizing pipes and storage tanks, water retention time (WRT) increases, which may support opportunistic pathogen (OP) growth. Decreasing pipe diameters would allow lower flow volumes without increasing WRT. However, s...
