Underexpression of porin protein OmpF in agar-entrapped, sessile-like Escherichia coli.
The electrophoretic patterns of the outer membrane proteins of agar-entrapped Escherichia coli cells were found to be different from those of free organisms. In particular, the porin protein OmpF was underexpressed in immobilized bacteria, that displayed enhanced resistance to latamoxef.
