Intracellular pH of baker’s yeast
Tóm tắt
The distribution of bromophenol blue between the cell and the medium was used to calculate the intracellular pH of yeast. In buffered media the intracellular pH exhibited a plateau at pH
i
=5.8 for low external pH values and another at pH
i
=7.6 for high external pH values. The production of H ions by the yeast during utilization of glucose is not accompanied by an alkalinization of the cell interior. The pH
i
even decreases somewhat in the presence of glucose and K ions.
