摘要:
研究了盐度对杜氏盐藻(Dunaliella salina)的生理生化效应。结果表明该藻适于生活在盐度为6~7倍海水的试验水中(海水盐度为33.5)。在此盐度中其光合速率、细胞增长速率、光合色素增长速率,游离氨基酸总量及多聚不饱和脂肪酸总量均高于生活在其它盐度的藻。

Effect of seawater satinity on free amino acid and fatty acid of Dunaliella salina
Abstract:
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 beter 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.
Key words:  linity  Dunaliella salina  free amino acid  faty acid
