Impact of milk processing on the generation of peptides during digestion
Martinus Gijs, Guy Vergères, Flurina Schwander, Reto Portmann
Milk processing may induce changes in dairy product composition and influence digestibility and nutrient bioavailability. Differences in protein degradation and peptide generation were studied for beta-lactoglobulin and alpha(S1)-casein from commercially a ...
Elsevier Sci Ltd2014ENERGY STORAGE: LIQUID CH4 AND CO2 NETWORK INTEGRATION
In this project, we will study the energy storage with liquid methane linked to a CO2 network that provides heat for district heating. The generated methane enters an hybrid cycle composed of a solid oxide fuel cell and turbines to generate electricity. Th ...
2014Constant-yield control of continuous bioreactors
The process of anaerobic digestion is a common application in the treatment of industrial and communal wastewater treatment plants. The biochemical reactions taking place inside the fermenter can be described by a system of first order differential equatio ...
Elsevier Science Sa2013Bacterial Resource Management for Nutrient Removal in Aerobic Granular Sludge Wastewater Treatment Systems
The approach of wastewater treatment has shifted towards a holistic view in order to achieve sustainability in addition to environmental protection. The aerobic granular sludge (AGS) technology, which relies on the use of fast-settling granular biofilms ca ...
EPFL2013Identification of trigger factors selecting for polyphosphate- and glycogen-accumulating organisms in aerobic granular sludge sequencing batch reactors
Christof Holliger, David Gregory Weissbrodt
Nutrient removal performances of sequencing batch reactors using granular sludge for intensified biological wastewater treatment rely on optimal underlying microbial selection. Trigger factors of bacterial selection and nutrient removal were investigated i ...
Elsevier2013Bacterial selection for nutrient removal in aerobic granular sludge wastewater treatment systems
Christof Holliger, David Gregory Weissbrodt
The mechanism of bacterial selection was investigated in aerobic granular sludge wastewater treatment systems (i) to determine why biological nutrient removal (BNR) gets deteriorated during granulation start-up under wash-out dynamics, and (ii) to identify ...
2013Bacterial resource management for nutrient removal in aerobic granular sludge
A holistic approach was developed towards efficient bacterial resource management for nutrient removal from wastewater in aerobic granular sludge sequencing batch reactors. Multiple reactor experiments from granulation start-up to operation at steady-state ...
2013The restricted metabolism of the obligate organohalide respiring bacterium Dehalobacter restrictus: lessons from tiered functional genomics
Christof Holliger, Julien Maillard, Aamani Rupakula Boyanapalli, Hauke Smidt
Dehalobacter restrictus strain PER-K23 is an obligate organohalide respiring bacterium, which displays extremely narrow metabolic capabilities. It grows only via coupling energy conservation to anaerobic respiration of tetra- and trichloroethene with hydro ...
2013Thermo-chemical production of F-T fuels from lignocellulosic biomass: Heat integration of gasification
François Maréchal, Guillaume Boissonnet, Emanuela Peduzzi
This study focuses on the process integration of gasification in the thermo-chemical conversion of lignocellulosic biomass into liquid fuels thorough gasification and Fischer-Tropsch (F-T) synthesis (biomass to liquids, BtL). Two main gasification technolo ...
2013Functional Genotyping of Sulfurospirillum spp. in Mixed Cultures Allowed the Identification of a New Tetrachloroethene Reductive Dehalogenase
Christof Holliger, Julien Maillard, Géraldine Florence Buttet
Reductive dehalogenases are the key enzymes involved in the anaerobic respiration of organohalides such as the widespread groundwater pollutant tetrachloroethene. The increasing number of available bacterial genomes and metagenomes gives access to hundreds ...
