The DEAD-box RNA helicase CshA is required for fatty acid homeostasis inStaphylococcus aureus

Staphylococcus aureusis an opportunistic pathogen that can grow in a wide array of conditions: on abiotic surfaces, on the skin, in the nose, in planktonic or biofilm forms and can cause many type of infections. Consequently,S.aureusmust be able to adapt r ...

E-coli-MS2 bacteriophage interactions during solar disinfection of wastewater and the subsequent post-irradiation period

César Pulgarin, Anna Carratala Ripolles, Stefanos Giannakis

In this study, the effect of MS2 bacteriophage on the inactivation of its Escherichia coli host was evaluated in an effort to recreate some the main factors governing solar disinfection of wastewater (namely microbial growth, infection, photonic flux). As ...

Constriction Rate Modulation Can Drive Cell Size Control and Homeostasis in C. crescentus

Suliana Manley, Seamus John Holden, Anna Archetti, Aster Louis K Vanhecke, Ambroise Justin Lambert, Felix Max Schaber

Rod-shaped bacteria typically grow first via sporadic and dispersed elongation along their lateral walls and then via a combination of zonal elongation and constriction at the division site to form the poles of daughter cells. Although constriction compris ...

Microfluidic bacterial traps for simultaneous fluorescence and atomic force microscopy

Georg Fantner, Jonathan David Adams, Oliver Peric, Mélanie Thérèse Marie Hannebelle

The atomic force microscope has become an established research tool for imaging microorganisms with unprecedented resolution. However, its use in microbiology has been limited by the difficulty of proper bacterial immobilization. Here, we have developed a ...

Modelling bacterial selection during the plug-flow feeding phase of aerobic granular sludge biofilm reactors

Christof Holliger, David Gregory Weissbrodt

A mathematical model was developed to investigate hydraulic transport and bacterial selection during slow up-flow anaerobic feeding (0.9 m h-1) of wastewater across the settled bed of granular sludge biofilms used in column-type sequencing-batch reactors t ...

Bacterial Resource Management for Nutrient Removal in Aerobic Granular Sludge Wastewater Treatment Systems

David Gregory Weissbrodt

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 ...

Computational analysis of the interplay between tRNA competitive behavior and decoding type on the modulation of translation elongation rate

Vassily Hatzimanikatis, Julien Racle, Joana Raquel Pinto Vieira

There has been much discussion in the literature regarding the determinants of ribosomal decoding speed during the mRNA translation process. Computational results based on mechanistic models for ribosomal kinetics have predicted a major role for near-cogna ...

A quorum sensing-mediated switch contributes to natural transformation of Vibrio cholerae

Melanie Blokesch

There is a fundamental gap in our understanding of how horizontal gene transfer contributes to the enormous range of genetic variations that are observed among bacteria. The objective of our study was to better understand how the acquisition of genetic mat ...

Scanning Near-Field Optical Microscopy of Living Cells in Liquid, Elaboration of New SNOM Probes and Detection Methods

Kanat Dukenbayev

The aim of the present PhD thesis is the elaboration of new, home-made Scanning Near-field Optical Microscope (SNOM or NSOM), and the demonstration of its great potential for high-resolution topography and fluorescence investigations of soft and solid samp ...

Acidophilic bacteria in Deep Groundwaters of the Bohemian Cretaceous Basin after Extensive Uranium Leaching

Pierre Rossi

The Stráž pod Ralskem region is a part of the Bohemian Cretaceous Basin. The geological profile of the site consists of Quaternary river sediments, Middle Turonian sandstone, Lower Turonian siltstone and Cenomanian collector formed by friable sandstone con ...
