Effect of seawater satinity on free amino acid and fatty acid of Dunaliella salina
盐度变化对杜氏盐藻的游离氨基酸和脂肪酸含量的影响

In this paper the effects of seawater salinity on free amino acid and fatty acid of Dunaliella salina were studied. The result showed that D. salina lives better in middle salinity conc (6.0 to 7.0-fold conc) under which higher rate of photosynthesis , larger increment of cells and photosynthetic pigment, and more free amino acid and polyunsaturated fatty acid .
