In order to get the high liquefaction yield from marine algae cell mass to fuel oil, the effect of
salt stress on the accumulation of lipids and triacylglyceride in Dunaliella cells was
investigated. Although initial NaCl concentration higher than 1.5 M markedly inhibited cell
growth, increase of initial NaCl concentration from 0.5 (equal to sea water) to 1.0 M resulted
in a higher intracellular lipid content (67%) in comparison with 60% for the salt concentration
of 0.5 M. Addition of 0.5 or 1.0 M NaCl at mid-log phase or the end of log phase during …
