Role of extracellular compounds in Cd-sequestration relative to Cd uptake by bacterium Sinorhizobium meliloti

The role of bacterially derived compounds in Cd(II) complexation and uptake by bacterium Sinorhizobium meliloti wild type (WT) and genetically modified ExoY-mutant, deficient in exopolysaccharide production, was explored combining chemical speciation measu ...

Amine- and carboxyl-quantum dots affect membrane integrity of bacterium Cupriavidus metallidurans CH34

The present study examines the interaction of amine- and carboxyl- PEG core/shell quantum dots (QDs) with metal resistant bacterium Cupriavidus metallidurans CH34. The evolution of the number of QDs, their hydrodynamic radius, diffusion coefficients and si ...

BIOGEOGRAPHY AND SPATIAL VARIABILITY OF BACTERIAL COMMUNITIES ASSOCIATED WITH CHLOROETHENE – CONTAMINATED AQUIFERS

Christof Holliger, Pierre Rossi, François Gillet, Noam Shani

Numerous industries and facilities have been using chlorinated ethenes (CEs) as non-flammable solvents since the beginning of the 20th century. These compounds are known to persist in the environment, exerting adverse effects. They have been considered for ...

Effect of competing ions and complexing organic substances on the cadmium uptake by the soil bacterium Sinorhizobium meliloti

Rita Hajdu Schenk

In an effort to improve the understanding and prediction of Cd uptake by soil bacteria, adsorbed and intracellular Cd were determined in unpolluted and highly polluted model soil solutions within a concentration range spanning from 10-9 to 5  10-5 M of ca ...

Detection of bacteria based on the thermomechanical noise of a nanomechanical resonator: origin of the response and detection limits

Luis Guillermo Villanueva Torrijo

We have measured the effect of bacteria adsorption on the resonant frequency of microcantilevers as a function of the adsorption position and vibration mode. The resonant frequencies were measured from the Brownian fluctuations of the cantilever tip. We fo ...

Liquid-core capsules as a tool in biotransformations

The aim of this thesis was to develop a new type of liquid-core capsules obtained by co-extrusion using the laminar jet break-up technique. These capsules, composed of an organic phase as the core and a hydrogel membrane, were meant to be applied as an in- ...

Structure and metabolism of peptidoglycan and molecular requirements allowing its detection by the Drosophila innate immune system

Bruno Lemaitre

Peptidoglycan (murein) is a major essential and specific constituent of the bacterial cell wall. Its main function is to protect cells against the internal osmotic pressure and to maintain the characteristic cell shape. It also serves as a platform for the ...

Effect of microcapsule composition and short-term immunosuppression on intraportal biocompatibility

Jutta Christine Wandrey, David Hunkeler, Dianelys Sainz Vidal

With higher nutrient and oxygen supply and close contact to blood, the portal vein is a possible alternative to the peritoneal cavity for transplantation of encapsulated cells. Data regarding intraportal biocompatibility of microcapsules are lacking. Micro ...
