Cell Multiplication in a Salt-tolerant Strain of Chlorella saccharophila under Saline Condition

Abstract

Some mechanisms of the action of NaCl-hypertonicity on proliferation of cells and on the changes in dry weight per cell were examined in the present paper by using a strain MY701 of Chlorella saccharophila. The following two evidences were obtained; 1) the hypertonicity with NaCl led to a higher rate of photosynthesis and also increase in dry weight per cell and probably inhibited the rupture of mother-cell wall, and 2) the photosynthetic rate and the dry weight per cell tended to change differently from early phase to late phase. In other words, the response of the salt-tolerant strain of Chlorella to the salinity was different at successive development stages.
