Two-dimensional fluorescence difference gel electrophoresis analysis of Listeria monocytogenes submitted to a redox shock.

Résumé

The influence of redox alteration on the growth and proteomic pattern of Listeria monocytogenes was investigated. A redox shock was induced in cultures by addition of 3mM ferricyanide (FeCN) and 6mM dithiothreitol (DTT) to increase or to decrease respectively the redox potential naturally occurring at the beginning of growth. In both conditions, the reducing and oxidizing redox shock had a strong influence, decreasing the maximum growth rate by half compared to a control culture. The proteomic analysis of L. monocytogenes performed by two-dimensional difference gel electrophoresis (2D-DIGE) exhibited twenty-three proteins differentially expressed (P<0.05), among these, many were oxidoreductases, and proteins involved in cellular metabolism (glycolysis, protein synthesis), detoxification (kat) or adhesion (Lmo1634).
