Co-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 ...

Force 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 ...

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 ...

Proxies 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 ...
