    Effects of different media on the growth and proximate composition of dunaliella sp. at different growth phase
    (Universiti Malaysia Terengganu, 2014) Siti Anish Azahar
    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.
