Implantation of Bacillus pseudomycoides Chromate Transporter Increases Chromate Tolerance in Bacillus subtilis

Rizlan Bernier-Latmani, Barbora Bártová, Imrich Barak, Zuzana Chromiková

Chromium of anthropogenic origin contaminates the environment worldwide. The toxicity of chromium, a group I human carcinogen, is greatest when it is in a hexavalent oxidation state, Cr(VI). Cr(VI) is actively transported into the cell, triggering oxidativ ...

Probing the growth and mechanical properties of Bacillus subtilis biofilms through genetic mutation strategies

Chen Zhang, Lei Wang

Bacterial communities form biofilms on various surfaces by synthesizing a cohesive and protective extracellular matrix, and these biofilms protect microorganisms against harsh environmental conditions. Bacillus subtilis is a widely used experimental specie ...

Advances in the Sensing and Treatment of Wound Biofilms

Hubert Girault, Sorour Darvishi

Wound biofilms represent a particularly challenging problem in modern medicine. They are increasingly antibiotic resistant and can prevent the healing of chronic wounds. However, current treatment and diagnostic options are hampered by the complexity of th ...

Analysis of a bac operon-silenced strain suggests pleiotropic effects of bacilysin in Bacillus subtilis

Mustafa Demir

Bacilysin, as the simplest peptide antibiotic made up of only L-alanine and L-anticapsin, is produced and excreted by Bacillus subtilis under the control of quorum sensing. We analyzed bacilysin-nonproducing strain OGU1 which was obtained by bacA-targeted ...

Mechanistic insights into bacterial metabolic reprogramming from omics-integrated genome-scale models

Noushin Hadadi, Vikash Kumar Pandey, Anush Chiappino-Pepe, Merten Morales, Florence Mehl

Understanding the adaptive responses of individual bacterial strains is crucial for microbiome engineering approaches that introduce new functionalities into complex microbiomes, such as xenobiotic compound metabolism for soil bioremediation. Adaptation re ...

Single-cell studies of Mycobacterium smegmatis cell cycle using time-lapse fluorescence microscopy

Joëlle Xiao Yuan Ven

Cell division is one of the most primordial cellular processes and is essential for life propagation. It is composed of crucial events, namely genome duplication, chromosomes segregation and membrane separation. Failure of these processes will have dramati ...

Microbiological contamination of cosmetic products - observations from Europe, 2005-2018

Florentino Luciano Caetano Dos Santos

Background Although cosmetic products are not expected to be fully aseptic, their potential microbiological contamination might be dangerous, especially for immunocompromised patients. The extent of such contamination of cosmetics in Europe is poorly studi ...

Mechanisms of DNA Uptake by Naturally Competent Bacteria

Melanie Blokesch

Transformation is a widespread mechanism of horizontal gene transfer in bacteria. DNA uptake to the periplasmic compartment requires a DNA-uptake pilus and the DNA-binding protein ComEA. In the gram-negative bacteria, DNA is first pulled toward the outer m ...

Steel Wire Mesh as a Thermally Resistant SERS Substrate

Tomasz Radoslaw Szymborski

In this paper, we present novel type of Surface-enhanced Raman spectroscopy (SERS) platform, based on stainless steel wire mesh (SSWM) covered with thin silver layer. The stainless steel wire mesh, typically used in chemical engineering industry, is a chea ...

Bacterial traps and advances in nanobiotechnology for atomic force microscopy

Oliver Peric

The atomic force microscope (AFM) allows the analysis of living microorganisms in physiological conditions on the nanometer scale. The observation of bacteria in physiological aqueous medium necessitates a robust immobilization of the bacterium to the surf ...
