Escherichia coli intracellular pH, membrane potential, and cell growth.

We studied the changes in various cell functions during the shift to alkaline extracellular pH in wild-type Escherichia coli and in strain DZ3, a mutant defective in pH homeostasis. A rapid increase in membrane potential (delta psi) was detected in both the wild type and the mutant immediately upon the shift, when both cell types failed to control intracellular pH. Upon reestablishment of intra...

Growth of the Escherichia coli cell surface.

Phage T6 was used as a label to follow the growth of the outer membrane in a strain of Escherichia coli temperature sensitive for the production of the T6 receptor. Extension of the surface takes place at the cell poles. Small cells extend at only one pole, whereas larger cells grow from both poles. The change from unipolar to bipolar growth appears to depend on the attainment of a particular c...

Bilinear cell growth of Escherichia coli.

Recent electron micrograph measurements of bacterial dimensions in exponentially growing cultures of Escherichia coli support a model of bilinear increase in cell surface area and volume, with a sharp doubling in growth rate at a discrete age during the cell cycle. The results also indicate coordinate regulation of increase of surface area and volume.

Colicin V-treated Escherichia coli does not generate membrane potential.

Colicin V-treated Escherichia coli was inhibited in its capacity to carry out active transport of proline and was unable to generate a membrane potential. Colicin V also prevented membrane potential formation by isolated cytoplasmic membrane vesicles. We conclude that a primary effect of this colicin involves the cytoplasmic membrane as a target.

Cell Wall and Cytoplasmic Membrane of Escherichia coli

Cell Wall and Cytoplasmic M e m b r a n e of Escherichia coli.* BY EDOUAm) K~LLE~mEROER arm Azcro~Ea'rE RYTER. The existence of two envelopes in bacteria has been postulated to account for numerous observations related to the presence of an osmotic barrier with differential permeability (1, 2), the occurrence of free, metabolizing protoplasts (3), and the possibility of producing plasmolysis (1...
