ASPECTS OF THE ENERGETIC BALANCE OF PLANT-CELLS UNDER DIFFERENT SALT CONDITIONS

Aspects of the intracellular energetic balance were studied in assimil ating cells of Chlorella, grown in a medium with different concentrati ons of NaCl. The responses depending on salt concentration were reveal ed by a microcalorimetric method. The lower concentrations of NaCl (45 0 mM) induced an increase in the heat production by Chlorella. Under h igher salt concentration (550 mM), a sharp increase in heat production took place. This was probably connected with the cell destruction. In explaining the results, the protective mechanisms of Chlorella connec ted with energy redistribution under different salt conditions, are em phasized.
