Outer membrane Modifications of Pseudomonas fluorescens MF37 in Response to Hyperosmolarity

The effect of hyperosmotic condition on the outer membrane protein (Omp) composition of Pseudomonas fluorescens was investigated by proteomic analyses. The abundances of 12 proteins, including porins, lipoproteins, and the flagella subunit FliC, were modified. This was at least partly explained by a...

Zusammenfassung:	The effect of hyperosmotic condition on the outer membrane protein (Omp) composition of Pseudomonas fluorescens was investigated by proteomic analyses. The abundances of 12 proteins, including porins, lipoproteins, and the flagella subunit FliC, were modified. This was at least partly explained by altered gene expression, as shown by mRNA level study. In agreement with Omp changes, hyperosmotic condition resulted in vesicle formation and modifications of mobility and antibiotic susceptibility.
