Abstract:
Microalgae Dunaliella sp. has been examined for the growth rate and its proximate
composition under different growth phase. The growth rate of Dunaliella sp. showed
there are no significant different (P>0.05) when culture in Conway and F2 media even
thought the cell density of Dunaliella sp. in F2 media is higher than the cell density of
Dunaliella sp. in Conway media. It only takes 7 days for Dunaliella sp. to reach its
maximum cell density in F2 media and it takes 9 days to reach its maximum cell density
in Conway media. The highest cell density of Dunaliella sp. in F2 media is 7 .8 x 10
6
cells
mL-
1
while for Conway media is 4.1 x 10
6
cells mL-1. The proximate composition of
Dunaliella sp. such as protein, carbohydrate and lipid was study at lag, log and stationary
phase in both F2 and Conway media.
