Bactericidal effect of tetracycline in E. coli strain ED1a may be associated with ribosome dysfunction

Camille Véronique Bernadette Goemans, Christian Eugen Zimmerli, Martin Beck

Ribosomes translate the genetic code into proteins. Recent technical advances have facilitated in situ structural analyses of ribosome functional states inside eukaryotic cells and the minimal bacterium Mycoplasma. However, such analyses of Gram-negative b ...

Engineering extracellular electron transfer for enhanced energy harvesting in microbial electrochemical devices

Mohammed Mouhib

Microorganisms known as exoelectrogens evolved the ability of transporting electrons across insulating biological membranes. In a physiological context, this enables respiration on extracellular electron acceptors and electron transfer to other organisms. ...

Sulfurospirillum diekertiae sp. nov., a tetrachloroethene-respiring bacterium isolated from contaminated soil

Christof Holliger, Julien Maillard, Junxiong Wang

Two anaerobic, tetrachloroethene- (PCE-) respiring bacterial isolates, designated strain ACSDCE T and strain ACSTCE, were characterized using a polyphasic approach. Cells were Gram-stain-negative, motile, non-spore-forming and shared a vibrioid- to spirill ...

Genotype-Dependent Kinetics of Enterovirus Inactivation by Free Chlorine and Ultraviolet (UV) Irradiation

Tamar Kohn, Shotaro Torii

Inactivation kinetics of enterovirus by disinfection is often studied using a single laboratory strain of a given genotype. Environmental variants of enterovirus are genetically distinct from the corresponding laboratory strain, yet it is poorly understood ...

Interbacterial competition and anti‐predatory behavior of environmental Vibrio cholerae strains

Melanie Blokesch, Natalia Carolina Drebes Dorr

Vibrio cholerae isolates responsible for cholera pandemics represent only a small portion of the diverse strains belonging to this species. Indeed, most V. cholerae are encountered in aquatic environments. To better understand the emergence of pandemic lin ...

Variability in Disinfection Resistance between Currently Circulating Enterovirus B Serotypes and Strains

Tamar Kohn, Simon Meister, Marius Klinger, Matthew Eric Verbyla

The susceptibility of waterborne viruses to disinfection is known to vary between viruses and even between closely related strains, yet the extent of this variation is not known. Here, different enteroviruses (six strains of coxsackievirus B5, two strains ...

High-throughput microfluidic platforms applied to immunoassay-based diagnostics and environmental monitoring

Francesca Volpetti

The research presented in this thesis is motivated by the aim to employ microfluidic devices for high-throughput analysis. Two applications, in particular, have been explored: diagnostics and environmental sensing. Miniaturization and multiplexing of labor ...

Molecular phylogeny suggests transfer of Hemidiscus into Actinocyclus (Coscinodiscales, Coscinodiscophyceae)

Lu Wang

Hemidiscus cuneiformis, type of the family Hemidiscaceae, is a diatom with a distinctive semi-circular shape in valve view. A strain of H. cuneiformis was established from the coastal region of the tropical southwestern Atlantic Ocean off Brazil. Cells of ...

Plasmonic nanohole array biosensor for label-free and real-time analysis of live cell secretion

Hatice Altug, Xiaokang Li, Filiz Yesilköy, Alexander Belushkin, Maria Soler Aznar, Cenk Ibrahim Özdemir

Cell secretion dynamics plays a central role in physiological and disease processes. Due to its various temporal profiles, it is essential to implement a precise detection scheme for continuous monitoring of secretion in real time. The current fluorescent ...

Miniaturized Dielectric Elastomer Actuator for Mechanical Stimulation of Monolayer Cell Cultures

Alexandre Poulin

This thesis advances the field of dielectric elastomer actuators (DEAs) through the development of device designs, fabrication processes, strain characterization technique and modelling tool. It provides the first demonstration that DEAs can be interfaced ...
