Gaseous NO₂ induces various envelope alterations in Pseudomonas fluorescens MFAF76a.

ABSTRACT: Anthropogenic atmospheric pollution and immune response regularly expose bacteria to toxic nitrogen oxides such as NO^• and NO₂. These reactive molecules can damage a wide variety of biomolecules such as DNA, proteins and lipids. Several components of the bacterial envelope are susceptible to be damaged by reactive nitrogen species. Furthermore, the hydrophobic core of the membranes favors the reactivity of nitrogen oxides with other molecules, making membranes an important factor in the chemistry of nitrosative stress. Since bacteria are often exposed to endogenous or exogenous nitrogen oxides, they have acquired protection mechanisms against the deleterious effects of these molecules. By exposing bacteria to gaseous NO₂, this work aims to analyze the physi
