Robust and sustainable cultivation of microalgae: recycling of nitrogen from liquid digestate and control of biological contamination

The present doctoral thesis aimed to achieve a robust cultivation of microalgae by recycling nitrogen from a liquid digestate. However, the use of non-sterile nutrient source increases the risks of contamination of undesired organisms such as bacteria, vir ...

Identification of a Dps contamination in Mitomycin-C–induced expression of Colicin Ia

Henning Paul-Julius Stahlberg

Colicins are bacterial toxins targeting Gram-negative bacteria, including E. coli and related Enterobacteriaceae strains. Some colicins form ion-gated pores in the inner membrane of attacked bacteria that are lethal to their target. Colicin Ia was the firs ...

Specific Protein-Membrane Interactions Promote Packaging of Metallo-beta-Lactamases into Outer Membrane Vesicles

Matteo Dal Peraro, Alessio Prunotto, Guillermo Bahr

Outer membrane vesicles (OMVs) act as carriers of bacterial products such as plasmids and resistance determinants, including metallo-beta-lactamases. The lipidated, membrane-anchored metallo-beta-lactamase NDM-1 can be detected in Gram-negative OMVs. The s ...

Microfluidic culture platforms for C. elegans bacterial interaction and digestion studies at single-organism resolution

Vittorio Viri

Increasing interest in understanding fundamental biological processes, among which aging and nutrition, has led to the study of simple and powerful model organisms, as the round-worm Caenorhabditis elegans (C. elegans). The nematode, selected by Sydney Bre ...

Dynamic persistence of UPEC intracellular bacterial communities in a human bladder-chip model of urinary tract infection

John McKinney, Neeraj Dhar, Vivek Vijay Thacker, François Signorino-Gelo, Kunal Sharma, Thomas Marie Simonet

Uropathogenic Escherichia coli (UPEC) proliferate within superficial bladder umbrella cells to form intracellular bacterial communities (IBCs) during early stages of urinary tract infections. However, the dynamic responses of IBCs to host stresses and anti ...

HCN production from formaldehyde during the selective catalytic reduction of NOx with NH3 over V2O5/WO3-TiO2

Davide Ferri, Oliver Kröcher, Rob Jeremiah G. Nuguid

Raw exhaust gases may contain notable levels of formaldehyde that can negatively impact the efficiency of after -treatment systems. In the selective catalytic reduction (SCR) of NOx over V2O5/WO3-TiO2, formaldehyde was found to react with NH3 to produce HC ...

Spatiotemporal pattern formation in E. coli biofilms explained by a simple physical energy balance

Anne-Florence Raphaëlle Bitbol

While the biofilm growth mode conveys notable thriving advantages to bacterial populations, the mechanisms of biofilm formation are still strongly debated. Here, we investigate the remarkable spontaneous formation of regular spatial patterns during the gro ...

Outer membrane lipoprotein NlpI scaffolds peptidoglycan hydrolases within multi-enzyme complexes in Escherichia coli

Ann-Kristin Hov

The peptidoglycan (PG) sacculus provides bacteria with the mechanical strength to maintain cell shape and resist osmotic stress. Enlargement of the mesh-like sacculus requires the combined activity of peptidoglycan synthases and hydrolases. In Escherichia ...

Retention of E. coli and water on the skin after liquid contact

Tamar Kohn, Timothy R. Julian

The frequent contact people have with liquids containing pathogenic microorganisms provides opportunities for disease transmission. In this work, we quantified the transfer of bacteria—using E. coli as a model- from liquid to skin, estimated liquid retenti ...

The ETFL formulation allows multi-omics integration in thermodynamics-compliant metabolism and expression models

Vassily Hatzimanikatis, Pierre Guy Rémy Salvy

Systems biology has long been interested in models capturing both metabolism and expression in a cell. We propose here an implementation of the metabolism and expression model formalism (ME-models), which we call ETFL, for Expression and Thermodynamics Flu ...
