O. Tresse et al., UNDEREXPRESSION OF PORIN PROTEIN OMPF IN AGAR-ENTRAPPED, SESSILE-LIKEESCHERICHIA-COLI, Antonie van Leeuwenhoek, 72(4), 1997, pp. 271-274
The electrophoretic patterns of the outer membrane proteins of agar-en
trapped Escherichia coli cells were found to be different from those o
f free organisms. In particular, the porin protein OmpF was underexpre
ssed in immobilized bacteria, that displayed enhanced resistance to la
tamoxef.
