Functional and structural characterization of polyphosphate-accumulating organisms in aerobic granular biofilms

The "Aerobic Granular Sludge" (AGS) technology for wastewater treatment is basedon dense microbial biofilm in the form of granular aggregates that have an excellentsettling property allowing high biomass concentrations in bioreactors. This promisingbiologi ...

Oxidative Water Treatment: The Track Ahead

Urs von Gunten, Yun Ho Lee

Chemical oxidation has been applied in municipal water treatment for more than a century, initially for disinfection. In the early decades, chlorine disinfection was adopted in the fight against waterborne disease. However, the oxidative properties of chlo ...

Wastewater microorganisms impact microbial diversity and important ecological functions of stream periphyton

Kristin Schirmer, Ahmed Tlili

Effluents of wastewater treatment plants can impact microbial communities in the receiving streams. However, little is known about the role of microorganisms in wastewater as opposed to other wastewater constituents, such as nutrients and micropollutants. ...

Disentangle genus microdiversity within a complex microbial community by using a multi-distance long-read binning method: example of Candidatus Accumulibacter

Christof Holliger, Julien Maillard, Aline Sondra Adler, Marco Pagni, Simon Marius Jean Poirier

Complete genomes can be recovered from metagenomes by assembling and binning DNA sequences into metagenome assembled genomes (MAGs). Yet, the presence of microdiversity can hamper the assembly and binning processes, possibly yielding chimeric, highly fragm ...

Wastewater-based estimation of the effective reproductive number of SARS-CoV-2

Tamar Kohn, Krista Rule Wigginton, Xavier Fernandez Cassi, Timothy R. Julian

Background The effective reproductive number, Re, is a critical indicator to monitor disease dynamics, inform regional and national policies, and estimate the effectiveness of interventions. It describes the average number of new infections caused by a sin ...

Biochar and environmental sustainability: Emerging trends and techno-economic perspectives

Edgard Gnansounou

Environmental pollutants including emerging contaminants are a growing concern worldwide. Organic wastes, such as food waste, compost, animal manure, crop residues, and sludge are generally used as feedstock. The conventional treatment methodologies (prima ...

Multistability and Reversibility of Aerobic Granular Sludge Microbial Communities Upon Changes From Simple to Complex Synthetic Wastewater and Back

Christof Holliger, Aline Sondra Adler

Aerobic granular sludge (AGS) is a promising alternative wastewater treatment to the conventional activated sludge system allowing space and energy saving. Basic understanding of AGS has mainly been obtained using simple wastewater containing acetate and p ...

The effect of different organic substrates on the microbial communities of aerobic granular wastewater treatment sludge

Aline Sondra Adler

Aerobic granular sludge (AGS) is a promising alternative wastewater treatment to the conven- tional activated sludge system, allowing space and energy savings. This process is particularly suited for biological phosphorus removal, avoiding use of coagulant ...

Imaging the aerobic granular sludge microbial community using light-sheet fluorescence micros

Christof Holliger, Julien Maillard, Arnaud Michel Gelb, Karen Gemayel

One of the aims of wastewater treatment is the removal of phosphorus before the water is discharged into the environment. Since phosphorus concentrations in wastewater exceed the requirement of bacterial growth, biological phosphorus removal is based on th ...
