PH of the Medium and the Growth and Metabolism of Cells in Culture

  • Subhash C. Minocha
Part of the Forestry Sciences book series (FOSC, volume 24-26)


The regulation of intracellular pH is a fundamental physiological process of great significance to the growth and metabolism of plant cells (51,64). Since intracellular pH has wide ranging consequences for the transport of nutrients and hormones, and for enzymatic reactions in the cells, it is not surprising that cells devote a lot of energy to the regulation of cytoplasmic pH. The metabolic production and consumption of large quantities of H+ and OH within the cytoplasm constantly challenge the homeostatic mechanism of pH regulation in the cells. The cytoplasmic pH is usually maintained around 6.5 – 7.5, although local differences in the pH of cell organelles are quite common.
