Abstract
Dunaliella sp. can tolerate different degree of salt stress and can be used in large scale
cultivation and may be applied for specific uses. Thus in this study, the effect of different
salt treatment (10, 30 and 50 ppt) on the growth and biochemical composition of
Dunaliella sp. at different growth phase was investigated. Results showed that Dunaliella
sp. growth in term of cell density and optical density was significantly higher at 10 ppt
(9.39 x 10
6
cells mr') compared to 30 ppt (7.59 x 10
6
cells mr
1
) and 50 ppt (9.18 x 10
6
1
cells mr
). In addition, Dunaliella sp. grew faster and growth phase shorten in lower
salinity compared to higher salinity. The variation of salinity tested had influenced on the
biochemical composition of Dunaliella sp..
