Rapid detection of bacterial resistance to antibiotics using AFM cantilevers as nanomechanical sensors

Giovanni Dietler, Sandor Kasas, Giovanni Longo, Livan Bladimir Alonso Sarduy, Laura Rio Marques, Justin Terence Notz Pekkanen

The widespread misuse of drugs has increased the number of multiresistant bacteria1, and this means that tools that can rapidly detect and characterize bacterial response to antibiotics are much needed in the management of infections. Various techniques, s ...

The 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 ...

Lactate metabolism shift in CHO cell culture: the role of mitochondrial oxidative activity

Florian Maria Wurm, Martin Jordan, Mathieu Benjamin Stettler, Francesca Zagari

Lactate production is monitored in industrial processes as a crucial metabolite for cultured mammalian cells. Typically lactate is strongly produced during the exponential growth phase, while its net consumption is frequently observed when cells enter into ...

Atomic Force Microscopy Stiffness Tomography on Living Arabidopsis thaliana Cells Reveals the Mechanical Properties of Surface and Deep Cell-Wall Layers during Growth

Giovanni Dietler, Sandor Kasas, Charles Roduit, Christian Fankhauser

Cell-wall mechanical properties play a key role in the growth and the protection of plants. However, little is known about genuine wall mechanical properties and their growth-related dynamics at subcellular resolution and in living cells. Here, we used ato ...

A NanoDrop-based method for rapid determination of viability decline in suspension cultures of animal cells

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Mélanie Hubert

We describe a rapid method for monitoring the cell growth and decline phases in suspension cultures of animal cells. During the cell growth phase, ultraviolet (UV)-absorbing components in the medium are consumed, but at later times as cells begin to die, U ...

On the origin of basal stacking faults in nonpolar wurtzite films epitaxially grown on sapphire substrates

Nicolas Grandjean, Denis Martin, Tiankai Zhu

The microstructure of nonpolar heteroepitaxial wurtzite films (GaN and ZnO-based) is dominated by the presence of planar basal stacking faults (BSFs). In this paper, transmission electron microscopy studies of both GaN and ZnO nonpolar films oriented eithe ...

Dynamics of Microbial Community Structure of and Enhanced Biological Phosphorus Removal by Aerobic Granules Cultivated on Propionate or Acetate

Christof Holliger, Graciela Gonzalez Gil

Aerobic granules are dense microbial aggregates with the potential to replace floccular sludge for the treatment of wastewaters. In bubble-column sequencing batch reactors, distinct microbial populations dominated propionate-and acetate-cultivated aerobic ...

A simple high-yielding process for transient gene expression in CHO cells

Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Yashas Rajendra, Divor Kiseljak

Here we describe a simplified method for transient gene expression (TGE) in suspension-adapted Chinese hamster ovary (CHO) cells using polyethylenimine (PEI) for DNA delivery. Both the transfection and production phases of the bioprocess were performed at ...
