Specialized chemical probe techniques need to be used to measure the membrane potential or the intracellular pH (pHi) of the cyanobacterium Synechococcus R-2 (PCC7942). The pHi of Synechococcus is essentially a set point (apprxeq7.3) over a wide range of extracellular pH (pHo) from 7 to 11. Maintenance of the pHi is strongly Na+-dependent and the cells cannot tolerate acid pHo.
