An In Vivo Microfluidic Study of Bacterial Load Dynamics and Absorption in the C. elegans Intestine

Martinus Gijs, Thomas Lehnert, Vittorio Viri, Maël Arveiler

Caenorhabditiselegans (C. elegans) has gained importance as a model for studying host-microbiota interactions and bacterial infections related to human pathogens. Assessing the fate of ingested bacteria in the worm's intestine is therefore of great interes ...

Wastewater and green waste biorefinery Degradation of simple sugars using mixed cultures of purple non-sulfur bacteria: an insight into microbial interactions

Guillaume Crosset-Perrotin

Purple non-sulfur bacteria (PNSB) are phototrophic organisms that have raised interest for both industrial and domestic wastewater treatment and valorization because of their very high assimilation (~1 g CODX g-1 COD substrate) and valuable compounds produ ...

Ammonia as an in-situ sanitizer: influence of virus genome type on inactivation

Tamar Kohn, Loïc Decrey, Shinobu Kazama

Treatment of human excreta and animal manure (HEAM) is key in controlling the spread of persistent enteric pathogens such as viruses. The extent of virus inactivation during HEAM storage and treatment appeared to vary with virus genome type, though the rea ...

Polyphosphate - a key biopolymer in aerobic granular sludge technology

Christof Holliger, Aline Sondra Adler, Arnaud Michel Gelb

Polyphosphate is the key biopolymer in wastewater treatment (WWT) processes applying enhanced biological phosphorus removal (EBPR) by polyphosphate-accumulating organisms (PAO). Alternating anaerobic (no oxygen and no nitrate) and aerobic phases is used to ...

Faecal sludge treatment: Optimization of Ascaris eggs enumeration and inactivation, and start-up of an anaerobic thermophilic acid-phase digester

Léa Cécile Randin

Faecal sludge (FS) accumulates in onsite sanitation technologies, which play a prevailing role in low- and middle-income countries. However, FS management is generally lacking. FS is usually directly discharged in the environment despite its high organic l ...

Evaluation of pathogens inactivation during thermophilic anaerobic digestion of faecal sludge

Karin Valentine Gallandat López

There is an urgent need to develop comprehensive and sustainable sanitation systems in developing countries, including faecal sludge (FS) treatment technologies that help reduce environmental and human health risks. Anaerobic digestion (AD) is widely used ...

Assessment of organic waste availability and suitability for the co-digestion of faecal sludge in Vietnam

Adeline Mertenat

This Master thesis comes within the framework of the PURR project (Partnership for Urban Resource Recovery), which is a collaboration between the Department of Water and Sanitation in Developing Countries (Sandec) at the Swiss Federal Institute of Aquatic ...

Advantages and limits of co-digestion in wastewater treatment plants – comparison to co-digestion in agriculture

Nathalie Bachmann

The Master Project offers a survey on several aspects of co-digestion in wastewater treatment plants (WWTP) and in agriculture. The description of the legal context and the technical processes present the basis for the subsequent analysis of the co-digesti ...

Aerobic granular sludge formation and performance at 30 and 35°C in sequencing batch bubble-column reactors

Christof Holliger, Graciela Gonzalez Gil, Sirous Ebrahimi, Sébastien Gabus, Maryam Hosseini

Aerobic granular sludge-based reactors represent an attractive alternative to conventional activated sludge systems due to their small footprint and their low energy consumption and excess sludge production. The granules developed in such systems have high ...

Improvement of acetate production from lactose by growing Clostridium thermolacticum in mixed batch culture

Jean-Paul Schwitzguebel, Christophe Collet

Aims: The objective of this study was to increase the acetate production by Clostridium thermolacticum growing on lactose, available as a renewable resource in the milk and whey permeate from the cheese industry. Methods and Results: Experiments for increa ...
