Microbial genome collection of aerobic granular sludge cultivated in sequencing batch reactors using different carbon source mixtures
Christof Holliger, Aline Sondra Adler, Laetitia Janine Andrée Cardona, Jaspreet Singh Saini, Pilar Natalia Rodilla Ramírez, Ruizhe Pei
Aerobic granular sludge (AGS) consists of a microbial consortium that has an important role in wastewater treatment. This study investigates AGS microorganisms cultivated in a laboratory-scale sequencing batch reactor. Metagenomic sequencing was conducted ...
Amer Soc Microbiology2024Functional 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 ...
EPFL2023Effect of wastewater treatment and environmental exposure on an enterovirus population
Odile Marie Clotilde Hervás de Nalda-Larivé
The presence of viruses in recreational water can present a risk for human health and wastewater effluent is a source of virus in the environment. Their persistence in the environment influences their probability to find a new host. Studies have shown that ...
EPFL2022Co-culture of microalgae-activated sludge for wastewater treatment and biomass production: Exploring their role under different inoculation ratios
Florian Frédéric Vincent Breider
In this study, mixed culture (microalgae:activated sludge) of a photobioreactor (PBR) were investigated at different inoculation ratios (1:0, 9:1, 3:1, 1:1, 0:1 wt/wt). This work was not only to determine the optimal ratio for pollutant remediation and bio ...
2020Force microscopy of the Caenorhabditis elegans embryonic eggshell
Martinus Gijs, Thomas Lehnert, Roger Philippe Krenger
Assays focusing on emerging biological phenomena in an animal's life can be performed during embryogenesis. While the embryo of Caenorhabditis elegans has been extensively studied, its biomechanical properties are largely unknown. Here, we demonstrate that ...
NATURE PUBLISHING GROUP2020Imaging 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 ...
2019Proxies to monitor the inactivation of viruses by ozone in surface water and wastewater effluent
Urs von Gunten, Tamar Kohn, Camille Wolf, Annalisa Pavese
Ozone treatment is an effective barrier against viral pathogens, therefore it is an integral part of many water and wastewater treatment trains. However, the efficacy of ozone treatment remains difficult to monitor, due to the lack of methods to track viru ...
2019Influence of Wastewater Composition on the Microbial Communities of Aerobic Granular sludge
Christof Holliger, Julien Maillard, Aline Sondra Adler, Valérie Berclaz, Marie Christelle Horisberger, Eva Reynaert
Aerobic granular sludge (AGS) is an emerging technology offering an alternative wastewater treatment with a reduced footprint compared to conventional activated sludge systems. Basic understanding of AGS processes has mainly been obtained in laboratory-sca ...
2019Evolution of Microbial Communities and Nutrient Removal Performances of Aerobic Granular Sludge during Change of Substrates
Christof Holliger, Julien Maillard, Aline Sondra Adler, Arnaud Michel Gelb, Valérie Berclaz, Marie Christelle Horisberger
Aerobic granular sludge (AGS) is a promising alternative wastewater treatment to the conventional activated sludge system, allowing substantial space, energy and chemichal products savings. Basic understanding of this processes has mainly been obtained in ...
