Abstract :

Abstract[1] In this study, increase of cell density of Dunaliella tertioletca was evaluated by four cultivation mediums including Conway, Guillard, Sato and TMRL mediums in the same conditions, including the amount of light 2000 to 5000 lux, temperature at 22.5-24 degrees Celsius, salinity 25 ppt, pH 8.5 and the same 24-hour aeration for 16 days. The results showed that among the four mediums with different chemical components, the highest rate of increase in cell density obtained in TMRL medium (P<0.05), although the cell density rates that obtained in Conway and Guillard medium were not different significantly (P>0.05), but increase of cell density in algae in Sato medium was less than the other treatments (P>0.05). Therefore, we can pull a result that Guillard, TMRL and Conway mediums are suitable for increase of cell density in this algae species in vitro, although TMRL medium usually is used for outdoor algae cultivations. * Corresponding Authors; Email: [e-mail]
