In contrast to enzymatic adaptation, osmotic adaption is possible with T4‐infected Escherichia coli B cells. After an osmotic shift from 220 mOsM to 690 mOsM the intracellular content of potassium rises in infected cells as well as in uninfected cells. After osmotic shock the involved TrKA transport system shows an increased discrimination against rubidium (Rb + ) and for potassium (K + ).
